a wise man learns not only from his own experience, but also from someone else's. The peculiarities of acquiring life experience were explained by the Russian poet A.S. Pushkin and the English writer Oscar Wilde. According to the first: "... experience, son of difficult mistakes ..."... Oscar Wilde confirmed that "... experience is the name we give to our past mistakes ..."... Talking about the experience of working with Geberit products, I would like to note that experience is formed not only from mistakes, but also from luck.

Geberit rainwater systems are widely used in the construction of large warehouse complexes offering full set warehousing services. Warehouse facilities up to half a kilometer long and with a total area of ​​500 thousand m2 are not uncommon. For such objects, the most economical application is flat roofs... The organization of drainage from such roofs becomes a difficult and responsible engineering task, and often the laying of pipelines is gravity storm sewer is an impossible or expensive solution. In these conditions good option is the use of Geberit Pluvia siphon vacuum drainage systems.

The principle of operation and high throughput of this drainage system allow it to be used in a wide variety of applications: flat roofs, domed and arched roofs of various curvatures, inversion and green roofs - both with extensive and intensive greening. Geberit Pluvia is used especially effectively in projects such as factories, warehouses, shopping centers, airports, hotels, sports centers, etc.

The advantages of the Geberit Pluvia siphon system in comparison with a traditional gravity system are as follows: reduction in the number of roof outlets, risers and pipes; reducing the diameter of pipes and building volume of the system; no slope of horizontal pipelines, which on large roofs can reach several meters; lack of pipelines at the base of the building; decrease in the number of releases to external networks; high self-cleaning ability of the system; optimization of external networks by transferring issues to one side; the possibility of preliminary manufacturing of system units.

The Geberit Pluvia siphon system consists of a specially designed rain outlet, piping and a fixing system. The funnels of the siphon system ensure effective collection of water from the roof, preventing air from entering the system. The Geberit Pluvia fastening system facilitates the assembly and installation of pipelines and prevents pipe deformation due to temperature and dynamic influences. All funnels can be equipped with an anti-freeze heating element during the transition season (spring and autumn). The unique design of the Geberit Pluvia roof outlets provides the flexibility of the possible design solutions and speeds up the installation.

Geberit has developed its own calculation methods and computer program Geberit Proplaner. The hydraulic calculation of the siphon stormwater system is aimed at determining the diameters of the pipelines that provide the closest match between the available head and pressure losses (local and linear) in individual sections.

Geberit specialists systematically track and organize the experience in the design, construction and operation of Pluvia siphon rainwater drainage systems. As a result of this work, the most typical mistakes and their reasons. Here is a short list of individual errors and groups of erroneous actions.

Mistake # 1

This is an item selection error. For example, the configuration of the funnels does not correspond to the type of roofing material and roof structure. Sometimes they make changes to the design of the stormwater system. This often happens because the design did not take into account all the features of the project. As a result, installers are forced to order additional “correct” components. Installers sometimes try to install non-standard components on the funnels themselves. Sometimes they try to find solutions right on construction site, using improvised means and a large amount of sealant and with an unpredictable result.

Mistake # 2

There may be a mistake in the choice of fastening the pipelines of the stormwater system: it happens that this choice is made without taking into account the features of building structures. So, the absence of the necessary fixed supports can lead to increased vibrations of pipes, their swaying. In the absence of expansion joints on vertical risers (with the so-called "rigid installation"), great forces arise in the pipeline due to temperature changes, it is necessary to install pipe clamps on studs of large diameters - from 1 / 2ʺ to 2ʺ. Clamps and studs of this size are extremely difficult to find on sale. In addition, the force at the points of attachment of such supports is very significant. And not all building construction can perceive them. The absence or improper installation of supports can also cause deformation of the pipelines.

Mistake # 3

It consists in combining roof outlets in one system installed on roof sections with a height difference of more than 4 m. This may be due to attempts to simplify the system and reduce its cost. The peculiarities of the hydraulic regime inside the siphon system can result in the outflow of water through the funnels in the lower sections of the roof.

Mistake # 4

Connection of roof sections with a total area of ​​more than 5000 m2 to one riser. This is due to attempts to simplify the system. This limitation makes it possible to reduce the diameters of pipelines, simplify their installation and operation.

Mistake # 5

Errors in determining the estimated flow rate of rainwater. The reasons for this kind of erroneous actions are different: inaccuracies in calculating the catchment area on complex roofs, choosing the wrong rain rate, etc. As a result, unstable operation of the system is possible (with an exaggeration of the estimated flow rate) or flooding of the roof (with an underestimation of the flow rate). An emergency overflow system can compensate for design errors associated with underestimated water consumption.

Mistake # 6

Installation errors are very critical. These include incorrect installation elements of funnels, deviation from the design pipe diameters, change in routing, errors about sealing joints with roofing material, defects welds etc.

All the above-mentioned disadvantages of working with stormwater systems are based on different reasons. Therefore, the measures to combat them are different. The very same reliable way avoiding possible shortcomings is a strict fulfillment of the requirements of the current building regulations and the installation instructions as well as the Geberit Pluvia planning guide.

Currently, drainage and melt water from the roofs of buildings it is carried out by unorganized discharge along the eaves of the eaves and by an organized drainage of water through external and internal drains. Internal drainage systems consist of drainage (receiving) funnels, risers, outlet (suspended and underground) pipelines and outlets. By the principle of action internal systems are divided into gravity and siphon systems.

In gravity systems, water is collected by drain funnels and removed from the roofs due to the slope in the outlet pipes. The calculation of pipelines is carried out based on their partial filling.

In siphon systems of internal drain Pluvia Swiss company Geberit the pipeline system is completely filled with water. There is a continuous water column from the funnel on the roof to the transition to the traditional gravity sewerage system... Rainwater accumulates on the roof surface to a certain level. Due to the pressure of the supporting water, the water column is pushed through the collection pipeline. When the water column starts to fall into vertical riser, in the entire drainage system, a reduced pressure is formed, due to which rainwater from the roof is sucked into the pipeline system.

Air should not be drawn into the siphon storm drain system to maintain complete filling of the pipeline and the siphon effect. This is achieved through tightness and accurate sizing of the piping system. Special design drainage funnels Pluvia and the complete tightness of the joints prevents air from entering the system. The funnels are equipped with a flow stabilizer, which allows rainwater to pass through only from the side and without air inclusions. For drainage pipelines used welded piping system Geberit HDPE .

Pipes and fittings Geberit HDPE connected by butt welding (in hard-to-reach places- electrically welded couplings) and are mounted using special fasteners and a large number of anchor supports without installing temperature compensators. Thus, the drainage system becomes completely sealed.

With light rain, the systemGeberit Pluvia acts similarly to a traditional gravity drainage system - the pipeline system is only partially filled with rainwater (partial filling). In heavy rain, the traditional gravity roof drainage system remains partially filled, while siphon system Geberit Pluvia completely filled with water due to the smaller diameter of the pipes (full filling). Due to this, a suction effect is created and the performance of the system increases dramatically.

Due to the high performance of the rainwater siphon systemGeberit Pluvia large roof areas can be drained with a small number of risers, which simplifies design, reduces costs and time construction works.

How the system works Pluvia determines its advantages over traditional system:

reducing the diameter of pipes and the number of funnels;

no slope horizontal sections drain and pipes at the base of the building.

Due to the high speed of the water, self-cleaning of the pipelines is ensured. The special flow regime inside the system allows to optimize external networks and transfer the outlets to the required side. Usage pipes Geberit HDPE make it possible to pre-assemble the system units.

Geberit Pluvia system can be used in various roofs: cold, warm, green roofs, etc. This system is most effective for large flat roofs and folded roofs with internal gutters. For both types of roofs there are different options executions, for example: non-insulated (non-insulated roof), insulated (insulated roof), insulated with a vapor barrier, suitable for the movement of people and vehicles, with greenery.

To calculate the system, use special program developed by the company Geberit, - ProPlanner Pluvia ... The program allows you to automatically calculate the diameters of all pipelines so that water from all sections of the roof, even located at different levels, is discharged at the same time without air sucking through the funnels. The program also performs hydraulic calculation of the system. The calculation results are given in tabular form and in the form of isometric drawings of risers. Program ProPlanner draws up a complete specification of materials required for installation.

The dimensions of the system depend on the intensity of the precipitation, the dimensions of the surface and the structure of the roof and the layout of the pipelines. When designing, it is necessary to check the roof, covering slabs for additionalloads from the backwater of the rainwater. This is especially true for light roofs.

When placing funnels Pluvia the following should be observed regulations :

Distribute the funnels as efficiently and evenly as possible:

Stir the funnels at the lowest point of the roof surface;

The maximum distance between two funnels on one drainage branch should not exceed 20 m;

to prevent malfunctions of the funnels, the latter should be stirred at a distance of at least 1 m from walls, parapets, etc.

Foreign waste water should not be directed into the systemGeberit Pluvia . Roof sections should be drained separately, if precipitation intensities are different, areas of more than 5000 m 2 and / or a height difference of more than 4 m have been covered.

Maximum value reduced pressure in the pipeline system for pipes Geberit HDPE is:

With diameters from 40 to 160 mm - 800 mbar;

With diameters from 200 to 315 mm - 450mbar;

With diameters from 200 mm to 315 mm (pipes P N 4) - 800 mbar.

Funnels Pluvia to drain rainwater from the roof can be directly connected to the piping system using a drain90 0 . All subsequent changes in direction to 90 0 in the pipeline system Pluvia can only be performed using two bends 45 0 .

V in the case of non-insulated roofs, and above all in the case of protruding overhangs, measures to protect against frost are required, T. j. some areas pipelines may freeze. In such cases, the zone funnels, as well as gutters, must be protected with a self-regulating cable that de-energizes the heating ( heated funnels is in the assortment of the companyGeberit ).

With a temperature difference between the drain, the roof surface and environment on pipe Geberit Pluvia Condensation may form. To prevent this, the piping of the system should be supplied with anti-condensation insulation.

Due to the high flow velocity in the pipeline, the noise level during the operation of the system Geberit Pluvia higher than with a traditional gravity internal drainage system. In buildings without special requirements for sound insulation, the system Geberit Pluvia can be used without additional measures. In buildings with high sound insulation requirements, noise-optimal piping is achieved by preventing sound transmission to the building structure (sound separation) and optimal placement funnels and pipelines. To prevent the spread of noise through the air, pipelines are laid in special soundproofed installation channels and / or external soundproofing is performed with with the help of a trumpet that or roll insulation.

Geberit Pluvia ends in either vertical or horizontal sections. Further, the pipeline with full filling ( Geberit Pluvia) turns into unpressurizedgravity system with partial filling (traditional gravity drainage system). To create such a transition, it is necessary to provide for an increase in the diameter of the pipeline.

Linear thermal expansion coefficient a forGeberit HDPE is 0.2 mm / (m ° C). Temperature difference? T = 50 0 С calls in caseGeberit HDPE linear expansion of the order of 10 mm per 1 m of the pipeline. Temperature difference? T = -30 0 С causes a linear shrinkage of about 6 mm per 1 m of the pipeline.

Changes in the length of the piping system caused by temperatures must be controlled by fastening the piping using fixed and movable supports. The fixed supports resist the forces from the temperature change and thus regulate the longitudinal elongation of the pipeline in a certain direction. The movable supports prevent lateral deflection of the pipeline during temperature changes and carry the weight of the water-filled pipeline.

System Geberit Pluvia is attached as follows:

Horizontal fastening - using the system fastenings Pluvia ;

Vertical fastening - using expansion joints;

Horizontal and vertical mounting - by means of rigid mounting.

For installation of horizontal sections of pipelines of the siphon system downpour Geberit Pluvia a specially designed system pipe fasteners Geberit PluviaFix ... The forces caused by temperature changes in the pipes are transmitted to the anchor supports and then to the steel square profile(tire), which compensates for the resulting mechanical stress. Mounting system Geberit PluviaFix guarantees quick installation, fewer points of attachment to the roof, the possibility of pre-assembly of individual units.

The Geberit Pluvia roof drainage system is based on the vacuum siphon principle. It consists of roof outlets, pipes and polyethylene fittings. low pressure(HDPE) Geberit, a sophisticated fixing system and professional support package from the manufacturer. Thanks to its siphon effect, Geberit Pluvia allows fast water drainage without requiring pipe slopes. Due to the high performance of the system, the number of risers and outlets can be minimized as compared to a traditional system.

Geberit Pluvia - Intelligent roof drainage system

Geberit Pluvia, the most common siphon roof drainage system, is used in different countries the world for 35 years.

Geberit Pluvia For modern architecture

Thanks to its reliability and design flexibility, Geberit Pluvia has been the choice of engineers and architects for the most important and demanding projects for many years. Unlike gravity drainage systems, Geberit Pluvia is the solution for modern architecture. Due to the absence of a slope of the horizontal pipes of the Pluvia system, it becomes possible to reduce the space under the roof required for the system, and to implement the most daring architectural and engineering solutions.

Various areas Geberit applications Pluvia

The Geberit Pluvia siphon roof drainage system is widely used in the industrial and commercial sector for roofs larger than 1000 m2. The principle of operation and high throughput of this drainage system allow it to be used in a wide variety of applications: flat roofs, domed and arched roofs of various curvatures, inversion and green roofs with both extensive and intensive greening. Geberit Pluvia is used especially effectively in projects such as factories, warehouses, shopping centers, airports, hotels, sports centers, etc.

Geberit Pluvia function

The Pluvia drainage system (translated from the Latin "Rain") is based on the gravitational-vacuum principle. When the liquid column moves under the action of gravity, a vacuum occurs, the maximum value of which is reached at the top point of the riser. The vacuum is transmitted through a horizontal collector to the water entry point - a receiving funnel. This siphon effect is due to the special design of the funnels and accurate calculation pipe diameters for maximum water filling. The principle of operation of the Pluvia system determines all of its advantages compared to the traditional system: a reduction in the diameter of pipes and the number of funnels, the absence of a slope of horizontal sections of gutters and pipes in the base of the building.

V country house it is impossible to do without installing a rainwater drainage system. It carries out the function of draining precipitation that was formed after melting snow and precipitation. In its absence, water flowing down the roof forms puddles around the house.

Photo: an example of a storm sewer

It is difficult to predict the amount of precipitation falling per year. With frequent rains and snowfalls, the water around the house does not have time to go into the ground. If the area around the building is tiled, the process becomes even more complicated.

As a result, on adjoining territory accumulation of water occurs. What can not drainage from the roof lead to in time?

This can lead to the following problems:

• flooding of the foundation of a residential, basement room;
• destruction of paths that are laid on the site;
• education unpleasant odors, as a result of waterlogging of the liquid;
• pollution of the covering, which is located in the yard;
• attracting mosquitoes and other insects in the summer;
• erosion of lawns.

The presence of puddles around the house is also unpleasant because all the rubbish rushes into the house. On the site after the rain is uncomfortable. The task of the storm sewer is to promptly remove wastewater into the reservoir and prevent the development of the described problems.

You can also drain water from the roof into ravines, with the exception of areas where sanatoriums are located, beaches or swimming places are organized, and stagnant ponds are located.

The discharge of effluents can be associated with mandatory requirement, concluding their preliminary cleaning.

Views

It is customary to distinguish between two types of rainwater drainage:

• point. To receive drains, they are installed, which receive water flowing down the gutters leading from the roof to the surface of the earth. The system must be covered with a grate to prevent the penetration of foliage and large debris;

Sand traps are placed underground to clean the drains from soil impurities. Such measures allow you to extend the life of the structure and prevent it.

Photo: spot

• linear. It is presented in the form of trays that form a network for receiving storm water. It is more often used in areas where a large amount of precipitation is planned. It can be installed not only under the drain pipe, but also along the house, mounted on an asphalt path.

Photo: linear

Any type of rainwater drainage system is installed taking into account the slope. The waters are discharged into the collector, where the waste is treated. The systems are equipped with filters to prevent clogging.

Open

Storm sewage systems differ in the way they drain precipitation. An open or surface system is a group of trays or other containers that receive drains and lead them off-site.

The tanks that perform the function of receiving water are somewhat buried and are mounted using cement mortar... They can also be installed in blind areas, paths or other elements.

On top of the gutters, they are covered with gratings, which are removed if necessary. Open rainwater drainage looks neat on the backyard area.

If you choose a decorative lattice, then the trays can be an excellent decoration for the landscape. Mostly open system set on small areas... It is considered to be easy to install and not costly in terms of finance.

Closed

This type involves deep drainage, the liquid is collected in special built-in products: trays, sand traps. Then it is sent to storm wells, and then, through a pump, flows into the sewage system.

After the collector, the effluent enters the purification systems or is discharged into reservoirs. More closed system it is used in cities, but it is also applicable for private territories.

Since the sewage system is more complex, its design requires certain knowledge. Installation is best done with the help of professionals. The system does an excellent job of its task, but its organization is associated with large financial costs.

Photo: closed

Mixed

It is a device consisting of underground pipes and surface trays. The removal of sediments occurs mainly by gravity. If the terrain does not allow them to flow on their own, then pumping equipment is installed.

For laying the water supply, the shortest path is chosen, connecting the receiving structure with the collector or outlet point into the reservoir.

For the pipeline, free-flow products are used: reinforced concrete, ceramic, asbestos-cement, plastic and concrete. The gutters that perform the drainage function are located around the entire perimeter of the structure.

Precipitation flowing from it falls into the pipe. It also receives liquid from storm water inlets and irrigation installations.

A mixed type storm sewer treatment system is used in large areas or when costs need to be reduced.

Principle of operation

Rainwater drainage is designed to collect melt water and precipitation that comes from the roof. Also, her task is to divert this fluid outside the site.

The principle of operation is based on collecting water at a single point, which comes from the roof or other areas on which drainage structures are installed. Then, by means of trays or a pipeline, the waste is removed from the private territory.

Thus, she performs three types of work:

• collection of precipitation;
• water purification;
• disposal of effluents.

Photo: the principle of rainwater drainage

The work is structured in such a way that waste is removed quickly and efficiently. As a result, waterlogging of the area does not occur, the soil dries out, not having time to flood the foundation of the building.

Video: how it works

System design

Important! It is recommended to start work related to the organization of rainwater drainage after finishing the foundation. It's good when the landscaping and paving of the local area has not yet been completed.

As preparatory phase, do vertical sprinkling with soil around the building, followed by compaction. This avoids deformation of the system during soil shrinkage.

The device can be divided into several stages:

• installation of equipment for collecting wastewater from the roof;
• installation of elements for removing precipitation from the site.

One of the key points in the placement of storm sewers is the definition of the place where the waste will be discharged and the way to carry out this action.

The factors influencing this decision include the features of the site around the building and the surrounding area. If nearby passes drainage ditch, there is a ravine, then it is enough to place the pipe at an angle and precipitation will be removed.

This is the easiest and most inexpensive way. A more costly option is to collect liquid in special wells, and then drain them using a pump.

Important! It is also necessary to provide for the installation of systems for collecting rainwater in places where the tiled covering is located with a contour-slope or has a large area.

The installation of such equipment is especially required at the entrance to the garage or other buildings. As a result of their action, the liquid collects quickly and puddles do not form.

It is best to equip storm sewers in the warm season, in the second half of summer. Duration of work for an average section of 10 hundred. the average is 1 month.

For the normal functioning of the system, the quality of the materials used is not so important as the observance of the slopes, the correct docking of the elements and timely preventive actions.

Photo: observance of slopes, correct joining of elements

Terms of use

Many owners of suburban real estate make mistakes when using the system. In order to save money, users often drain liquid from drainpipes into blind areas.

The result of such actions is their penetration into the soil, leading to subsidence and deformation of the foundation of the house. Minimal losses in this case are serious repairs.

Storm sewage requires preventive maintenance, including cleaning it. The procedure is simple and does not take much time. The service consists in cleaning gully from debris, and from wells from silt.

Prevention is carried out 2 times a year. Regular maintenance is also required, which includes flushing the trays. running water, clearing debris from gully baskets and cleaning sand traps.

Important! Waste should not be discharged into the drainage system, as this may lead to an increase in the level groundwater in the rain. As a result of such an error, the foundation is flooded. Poor-quality processing of joints leads to the same consequences.

Geberit

The equipment is a device that works, which occurs with the use in vacuum system siphon principle.

His work changes depending on the level of precipitation:

• The Geberit storm drain works as usual if it rains for a short time;
• at a large number precipitation for a short time, a vacuum is formed inside the system, with the help of which water from the funnels is sucked in with high power. The speed of its movement through the pipeline can be 12m / s.

Photo: Geberit storm drainage system

The gravitational-vacuum system stands out from the usual ones in that it easily adapts to any roof surface, so it is easy to install. It has good carrying capacity and it is not necessary to observe the slope when laying it.

The Geberit storm drain does not require high material costs.
It provides complete sealing due to the connection of its parts using hot welding.

For the installation of pipes, special fasteners are used. Installed system looks aesthetically pleasing and does not make much noise during operation.

The area of ​​application of the sewage system is extensive; it can be mounted on any roofs. It will be most beneficial to purchase it for large areas or roofs where it is impossible to use another system.

A storm sewer in a private house is required system, which is installed immediately after the completion of construction work related to the house. Its various types of water intake and discharge allow you to choose the best option.

Modern types of sewerage systems offer drainage of rainwater over large areas or areas where high level daily precipitation. Storm system differs in easy installation and uncomplicated maintenance.

, the European market leader in sanitary ware, introduces the Pluvia system, a siphon-operated rain shower for large flat roofs. Thanks to the special design of the rain funnels and pipes, its throughput is several times higher than that of conventional solutions. This enables Pluvia to cope with the heaviest rainfall.

Geberit Pluvia flat roof rainwater drain

The system uses components with optimized hydraulic performance. The design of the funnel, risers and pipes allows them to be filled with rainwater quickly and without air pockets. A continuous water column forms in the pipeline. Falling, this pillar creates a reduced pressure. This significantly increases the flow rate and capacity compared to conventional systems with the same pipe diameter.

“Complete drainage of rainfall from the roof is one of the conditions for the durability of any building. The high performance of the Pluvia system allows the building to be prepared for the heaviest rainfall and significantly reduces the cost of internal drainage networks, since much fewer rainwater funnels, risers and sewer pipelines, - comments Andrey Bilev, technical consultant for Geberit piping systems. - In addition, the high flow rate promotes self-cleaning of the structure and reduces the risk of clogging. The absence of slopes provides architects with maximum freedom in the design of the roof and utilities. "

A wide range of funnels, pipes and fittings makes it possible to adapt this system for buildings of any purpose. Customers and designers can always count on the manufacturer's technical support and advice on specific projects.

Pluvia pipelines are made of low-pressure polyethylene (HDPE) and are very convenient and easy to use. They are hermetically sealed by butt welding or electrofusion sleeves. The original fasteners, consisting of brackets and guides, allow you to reliably fix HDPE pipes under the roof. In addition, individual components of the system can be pre-assembled at the factory, which increases safety of work, facilitates and speeds up the arrangement of gutters at the facility.

Pluvia rain showers can be used for the construction of new storage, production, retail and sports facilities, as well as for the modernization of existing flat roofs. Due to the low stress on building structures this system is an optimal solution for drainage of rainwater from light roofs with large spans. In particular, the system was used during the reconstruction of the Luzhniki Grand Sports Arena.
