When choosing pipes it is worth considering that the MAPRESS series press connections are designed to pressure up to 16 bar, and MEPLA is on working pressure not exceeding 10 bar.

Operational, safe and neat installation

Construction technology with Geberit systems is significantly superior traditional methods Pipeline gaskets with welding, thread and soldering. It requires minimal preparation, and the entire process is carried out several times faster.

Getting Started to create pipelines based on Geberit press systems, the master first performs metering and incision of pipes according to the project. Cutting can be carried out both electromechanical and hand tool. After that, external and internal chamfer are removed, and on the pipe make it a mark of its fitting. Also, the ends of each product are cleaned from sowing and irregularities to get a perfectly smooth and clean surface that will provide a solid connection of the joints during installation.

Pipe bonds are made using the press fittings included in the Geberit system equipped with profile sealing rings of a unique design. It is these elements that are responsible for the tightness, reliability and durability of the connection. Also during the installation process, special equipment is involved, which allows you to adjust the reinforcement of Geberit:

• pipes with a diameter of 16-26 mm Geberit MEPLA series are usually connected using a manual tool;
• pipes of the Mapress and MEPLA series with a diameter greater than 26 mm are fastened with the use of electrical press tools.

It begins with network tracing and connecting prepared pipes using press fittings (pipes on the outlined depth are inserted into the extension of fitting). Next, by holding them between the crimp lips of the press tool, the wizard presses the start button, after which the compression process automatically begins. Under pressure a press fitting, a sealing ring and a pipe deform to a certain form, forming a durable, durable and sealed connection. Circling together two pipes, the wizard in the same way makes the installation of other elements, creating a pipeline of the desired length and configuration.

Advantages of using Geberit press systems

• High speed. The simplicity of pipe connection technology allows you to quickly create pipelines of any length when minimum costs time and means, which gives substantial cost savings and speeds up the whole process.
• Easy work. The use of compact and powerful special equipment makes work as simple as possible. And they are comfortable even in hard to reach places and close space.
• Connection reliability. As a result of using Geberit systems and special equipment Reliable pipelines with durable compounds with torsion rigidity and tightness are obtained.
• High aesthetics. In addition to the excellent characteristics of the Geberit connection have aesthetic appearance. It is precisely because of this that they can be used in projects providing for open pipe gasket.

Livneston for Flat Roofing Geberit Pluvia

The system uses components with optimized hydraulic characteristics. The design of the storm funnel, risers and pipes allows them to fill with rainwater quickly and without air pockets. The pipeline forms a solid water pole. Falling, this pillar creates reduced pressure. This significantly increases the flow rate and bandwidth compared to conventional systems with the same diameter of the pipes.

"A complete disparation of precipitation with a roof is one of the conditions of durability of any building. High performance of the Pluvia system allows you to prepare a building to the strongest rainstream and significantly reduces the costs of internal wastewater networks, as much smaller number of rainwater hoping funnels, risers and sewer pipelines, - comments Andrei Bilev, technical consultant on Geberit pipeline systems. - In addition, high flow rate contributes to self-cleaning design and reduces the risk of clogging. The lack of slopes provides architects maximum freedom when designing roofing and engineering communications. "

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

Pluvia system pipelines are made of polyethylene low pressure (PND) and very convenient and technologically in work. They are hermetically combined through the welding of jack or using electric welded couplings. Original mounts consisting of brackets and guides allow you to reliably fix pipes from PND under roofing overlap. In addition, individual nodes of the system can be pre-assessing in the factory conditions, which improves the safety of work, facilitates and speeds up the arrangement of the drainage at the facility.

Livnestok Pluvia can be used both in the construction of new warehouse, industrial, commercial and sports facilities and to modernize existing flat roofs. Due to the slight load on building structures this system is an optimal decision To remove rainwater from light roofs with large spans. In particular, the system was used with the reconstruction of Luzhniki's large sports arena.

Typical technological card (TTK) is based on the installation of the inner waterproofing of Geberit Pluvia.

TTK is designed to familiarize workers and engineering and technical workers with the rules for the production of works, as well as for the purpose of using construction projects, construction projects, other organizational and technological documentation.

Geberit Pluvia inner drainage system is widely used in industrial and commercial sectors for roofs with an area of \u200b\u200bmore than 1000 m. Principle of operation and high throughput of the drainage system allow you to use it in a wide variety of areas: flat roofs, dome and arched roofs of various curvatures, inversion and green roofs either with extensive and intense landscaping. The use of Geberit Pluvia is especially effective when designing factories, warehouses, shopping centers, airports, hotels, sports centers, etc.

2. General provisions

The system works on the principle of the siphon effect and uses the method of accurate calculation of pipe diameters. Prerequisite The work is 60-100% filling system, which is achieved by calculating the Proplanner Pluvia computer program.

Fig.1. The system consists of receiving funnels on the roof, pipes and fittings from Geberit PND, as well as the original steel fastener system.

The fluid falling in the standing column creates a vacuum and carries new portions of water from the roof. At the same time, a significant vacuum is created at the receiving funnel, followed by a sharp increase in the performance of the entire system.

Due to the siphon action, Geberit Pluvia allows you to quickly and effectively remove rainwater from large roofs at smaller pipe diameters, compared with traditional system. It does not require a bias in horizontal pipelines and temperature compensation. The system is mounted on the principle of rigid sealing on anchor supports. Reducing diameters and the number of pipes and risers leads to a reduction in the volume and cost of construction and installation work. Geberit Pluvia has absolute tightness due to butt welding pipes, occupies a smaller building volume and has the effect of self-cleaning due to high flow rates. According to the current construction standards, when the roof bonding is less than 1.5%, the estimated rainwater consumption for Moscow is 80 liters of C / ha (Q20). However, taking into account the changing climate and increasing the intensity of rainfalls, Geberit recommends navigate the value of 196 hp / ha (Q5), when the roof is biased to and over 1.5%. On the basis of this magnitude, the installation of the Geberit Pluvia system in large Auchan, Metro, MEGA-1 and other objects was calculated on the major hypermarkets. This system is confirmed by TU 4923-001-00284581-2004, approved by Plumbing Research Institute 25.11.2004.

The Geberit Pluvia system is based on a vacuum-siphon principle. It consists of roofing funnels, pipes and fittings from low pressure polyethylene (PND) Geberit, worked out by fastening systems and professional package of technical support services from the manufacturer. Due to the siphon principle of operation, Geberit Pluvia provides a quick water removal, without requiring a liner. High system performance allows you to maximize the number of risers and issues compared to the traditional system.

Thanks to the reliability and flexibility in the application of the Geberit Pluvia system, many years are used by leading architects and engineers when designing the most significant objects.

Fig.2. The absence of a slope of horizontal pipelines of the Pluvia system makes it possible to reduce the place under the roof required for the system, and implement the most bold architectural and engineering solutions

The pluvia drain system (translated from the lat. "Rain") is based on a gravitational and vacuum principle. When the fluid column moves under the action of gravity, there is a vacuum, the maximum value of which is achieved at the top point of the riser. The vacuum is transmitted along the horizontal collector to the point of the water entry - the receiving funnel. The syphony effect occurs due to the special design of the funnels and the exact calculation of pipe diameters, contributes to the maximum filling with water. The principle of operation of the PLUVIA system causes its advantages compared to the traditional system: reducing the diameter of the pipes and the number of funnels, lack of slope horizontal plots Drain and pipes at the base of the building.

Pipes are connected by hot welding method (in hard-to-reach places - electroplating clutches) and mounted using large number Anchor supports without installing temperature compensators. Thus, the drainage system becomes completely hermetic.

3. Organization and technology for performing work

The Geberit Pluvia system is attached as follows:

- horizontal mount - using the Pluvia attachment system;

- vertical mount - using compensatory couplings;

- Horizontal and vertical mounting - by hard mounting.

For mounting horizontal sections of the pipeline pipeline system, Geberit Pluvia was specially designed by the Fasteners of the Geberit Pluviafix pipelines. Efforts caused by temperature changes are transmitted to anchor supports and further on steel square profile (tire), which compensates for emerging mechanical loads. The Geberit PluviaFix installation system guarantees quick installation, fewer mounting points to the roof, the ability to pre-assemble individual nodes.

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

Storm systems Geberit is widely used in the construction of large warehouse complexes offering full set warehousing services. No rarity warehouse objects up to a half-kilometer and a total area of \u200b\u200b500 thousand m2. For such objects, the most economical is the use of flat roofs. The organization of drainage from such roofing becomes a complex and responsible engineering task, and often the laying of pipelines of the samotane storm sewage is an impossible or expensive solution. In these conditions good option It is the use of Geberit Pluvia water dilapidation systems.

The principle of operation and the high throughput of this drain system make it possible to use it in various applications: flat roofs, dome-shaped and arched roofs of various curvatures, inversion and green roofs - both extensive and intensive gardening. Geberit Pluvia applies especially effectively in projects such as plants, warehouses, shopping centersAirports, hotels, sports centers, etc.

The advantages of the Geberit Pluvia siphon system compared with the traditional self-e-system as the following: reducing the number of funnels, risers and pipelines; reduction of pipe diameter and system building volume; The lack of a slope of horizontal pipelines, which on large roofs can reach several meters; lack of pipelines at the base of the building; reducing the number of issues in external networks; high self-cleaning system of system; optimization of external networks by transferring out one way issues; The ability to pre-manufacture system nodes.

The Geberit Pluvia siphon system consists of receiving rave funnel of a special design, pipelines and fasteners. Funnels of the siphon system provide an effective collection of water from the roof, preventing air intake inside the system. The Geberit Pluvia fastener system facilitates the assembly and installation of pipelines, prevents the damage of pipes from temperature and dynamic effects. All funnels can be equipped heating element To protect against freezing in the transition season (spring and autumn). The unique design of the Geberit Pluvia funnel ensures the flexibility of possible design solutions And speeds up the installation.

In order to calculate the Geberit Liofone Liofone Systems created its own calculation methods and computer program Geberit Proplaner. The hydraulic calculation of the siphon system of the livnevel is aimed at determining the diameters of pipelines that ensure the closest correspondence between the pressure and pressure loss (local and linear) in separate areas.

Geberit specialists systematically monitor and systematize the experience of designing, construction and operation of Pluvia Liofone Siphon Systems. As a result of this work, the most typical errors And their causes. Let us give a brief list of individual errors and error groups.

Error number 1.

This is an element selection error. For example, the equipment of the funnel does not correspond to the type of roofing material and the roof design. Sometimes changes in the design of the livnevel system. It often happens because the design did not take into account all the features of the project. As a result, the installers are forced to order additional "correct" components. Installer are sometimes trying to independently put non-standard components on the funnels. Sometimes solutions are trying to find directly on construction site, Using primary means and a large amount of sealant and with an unpredictable result.

Error number 2.

An error is possible in choosing the fastening of the pipeline of the livnevel system: it happens that this choice is carried out without taking into account the characteristics of building structures. So, the absence of essential fixed supports can lead to reinforced pipe vibrations, their swinging. In the absence of compensatory couplings on vertical risers (with the so-called "hard installation"), large efforts occur in the pipeline due to temperature changes, the installation of pipe clamps on heels is necessary large diameters - from 1/2. Up to 2". Clamps and studs of such sizes are extremely difficult to find on sale. In addition, the effort in places of attachments of such supports is very significant. And not all building structures can perceive them. The absence or improper installation of the support can also cause strain pipelines.

Error number 3.

It consists in combining in one system of roofing funnels installed on the roof sections with a drop of heights of more than 4 m. This may occur due to attempts to simplify the system and reduce its cost. The features of the hydraulic regime inside the siphon system may result in watering water through the funnels in the lower parts of the roof.

Error number 4.

Connecting to one rising of the roof sections with a total area of \u200b\u200bmore than 5000 m2. This is due to attempts to simplify the system. This restriction allows you to reduce the diameters of pipelines, simplify their installation and operation.

Error number 5.

Errors when determining the estimated consumption of rainwater. The reasons for this kind of erroneous actions are different: inaccuracies in the calculation of the area of \u200b\u200bthe catchment on complex roofs, the choice of incorrect rain intensity, etc. As a result, an unstable operation of the system is possible (with the exaggeration of the calculated flow rate) or flooding (when a flow rate). The emergency overflow system can compensate for project errors associated with the understatement of water consumption.

Error number 6.

Mounting errors are very critical. These include invalid installation Elements of the funnels, deviation from the design diameters of pipes, changes in tracing, errors about sealing joints with roofing material, defects welded seams etc.

All named shortcomings of working with livnevel systems are based on different reasons. Therefore, measures to combat them are different. Same reliable way Avoid possible shortcomings - it is strictly fulfilling the requirements of valid construction Rules and installation instructions, as well as "Recommendations for the design of Geberit Pluvia".

Currently, the removal of rain and mavel Water With roofs of buildings, it is carried out inorganized discharge on the sinks of the eaves and organized water taps along the outer and inner waterproof. The internal hydrogen systems consist of drainage (receiving) funnels, risers, tap (suspended and underground) pipelines and issues. According to the principle of action internal systems We are divided into patrimonial and siphon systems.

In samotane systems, water is assembled with drainage funnels and removed from the roofs due to the slope in the discharge pipelines. Calculation of pipelines is performed based on the partial fill.

In siphon systems internal water station Pluvia. Swiss companies Geberit. The pipeline system is completely filled with water. There is a continuous water column from the funnel on the roof until the transition to the traditional self- sewage system. Rainwater accumulates on the surface of the roof to a certain level. Due to the pressure of the waterproof water, the water pole is pushed through the collecting pipeline. When the water pillar begins to fall in vertical riserIn the entire drainage system, reduced pressure is formed, due to which rainwater from the roof is absorbed into the pipeline system.

The air should not flow into the siphon livnefone system to maintain the full filling of the pipeline and the siphon effect. This is achieved by tightness and accurate selection of the size of the pipeline system. Special design waterbathing funnels Pluvia. And the complete tightness of the joints prevent air penetration inside the system. Funnels are equipped with a flow stabilizer that skips rainwater only on the side and without air inclusions. For drainage pipelines used system of welded pipelines Geberit. HDPE .

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

With non-intense rain systemGeberit. Pluvia. It acts similarly to the traditional samotane system of the drain - the pipeline system is only partially filled with rainwater (partial filling). With a strong rain, the traditional samotane system of the inner drain continues to be partially filled, while siphon system Geberit. Pluvia. Fully filled with water due to the smaller diameter of the pipes (full filling). Due to this, the suction effect and system performance increases sharply.

Due to the high performance of the siphon system of the LivnestokGeberit. Pluvia. Large areas of roofs can be drained to a small amount of standing, which simplifies design, reduces the costs and duration of construction work.

Principle of operation of the system Pluvia. Causes its advantages compared to the traditional system:

reduction of pipe diameters and the number of funnels;

lack of slope of horizontal sections of drain and pipes at the base of the building.

Due to the high water speed, self-cleaning of pipelines is ensured. Special flow mode inside the system allows you to optimize outdoor networks and transferring outlaits to the required side. Using pipe Geberit. HDPE allow the preliminary assembly of the system nodes.

Geberit Pluvia system It can be used in various roofs: cold, warm, roofs with landscaping, etc. This system is most effective for large flat roofs and folded roofs with internal gutters. For both types of roofs exist various options Performances, for example: uninsulated (displeasted roof), isolated (insulated roof), isolated with vapor barrier, suitable for moving people and vehicles, with landscaping.

To calculate the system used special program developed by the companyGeberit, - Proplanner. Pluvia. . The program allows you to automatically calculate the diameters of all pipelines so that water from all parts of the roof, even spaced at different levels, the air superstream has occurred simultaneously through the funnels. The program also performs the hydraulic calculation of the system. The results of calculations are issued in tabular form and in the form of isometric drawings of risers. Program Proplanner. Makes a complete specification of the materials required for installation.

The size of the system depends on the intensity of the drop-down precipitation, the size of the surface and the design of the roof and the laying of pipelines. When designing it is necessary to check the roof, coating plates for additionalloads from the opposite of the rainwater. This is especially true for light roofs.

When placed voroneok Pluvia. The following should be observed regulations :

Funnels to distribute as rationally, evenly:

Stir the funnel 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 violations of the functioning of the funnels, the latter should be stirred at a distance of at least 1 m from the walls, parapets, etc.

Extraneous waste wheels should not be sent to the systemGeberit. Pluvia. . Plots of the roof should be drained separately, if the intensity of precipitation is different, the plates were placed more than 5000 m 2 and / or the height difference more than 4 m.

Maximum value reduced pressure in the pipeline system for pipe Geberit. HDPE Amount:

With diameters from 40 to 160 mm - 800 mbar;

With diameters from 200 to 315 mm - 450bbar;

With diameters from 200 mm to 315 mm (pipe pN 4) - 800 mbar.

Funnels Pluvia. To remove the rainwater from the roof can directly connect to the pipeline system by removal90 0 . All subsequent changes to the direction on90 0 in the pipeline systemPluvia. It is allowed only with two taps45 0 .

IN the case of non-flared roofs and first of all in the case of protruding soles requires measures to protect against freezing,t. k. Some sitespipelines can freeze. In such cases zone funnels, as well as gutters, should be protected with self-regulating cable de-energizing heating ( heated funnels there is a range of companiesGeberit. ).

With the difference in the temperature of the drain, the surface of the roof and ambient on the trumpet. Geberit. Pluvia. Condensate can be formed. To prevent this system pipelines should be supplied anti-condensate isolation.

Due to the high flow rate in the pipeline noise level during system operationGeberit Pluvia. higher than with the traditional self-sewn system of inner drainage. In buildings without special requirements for sound insulation systemGeberit Pluvia. Can be used without additional events. In buildings with high sound insulation requirements optimal for noise, the pipeline laying is achieved by preventing sound transmission on construction construction (Sound separation) and optimal placementvoroneok and pipelines. To prevent the spread of noise through the air, the pipeline laying is carried out in special soundproofed circuit channels and / or produce outdoor sound insulation withusing tubular toy or rolled insulation.

Geberit. Pluvia. ends either on vertical or horizontal sites. Next, the pipeline with full filling (Geberit Pluvia) goes into non-pressureself-leveling system with partial filling (traditional sealer system of drain). To create such a transition, it is necessary to provide an increase in the diameter of the pipeline.

Linear temperature expansion coefficient but forGeberit. HDPE make up 0.2 mm / (m ° C). Temperature difference? T \u003d. 50 0 C causes in caseGeberit. HDPE Linear expansion of about 10 mm per 1 m pipeline. Temperature difference? T \u003d. -30 0 C causes a linear shrinkage of about 6 mm per 1 m pipeline.

The change in the length of the pipeline system caused by temperatures should be adjusted by the fastening of the pipeline using fixed and movable supports. Fixed supports counteract efforts from temperature change and these regulate the longitudinal extension of the pipeline in a specific direction. Movable supports prevent the lateral deviation of the pipeline at temperature changes and carry the weight of the water filled with water.
