Supports of lighting and power lines are used since electricity and lighting appeared everywhere. And, if at first posts for mounting wiring were made mainly from wood, then more technological materials are used to produce these structures.

However, this is not surprising, since metal and reinforced concrete supports, in comparison with structures, characteristic of the first half of the last century, are becoming more stronger and more stable to substantial loads.

Consider what features of modern lighting supports and power lines, as well as what and how they are made.

Features Lighting and LPP

It is no secret that power lines are cable (swallowed in soil) and air. Special reinforced concrete light supports have found widespread use in the device of air lines.

The installation of reinforced concrete supports can be performed in those regions where the estimated air temperature does not fall below -55 ° C. Such a limitation is due to the main features of production material. Concrete is characterized by the presence of multiple micropores and, as a result, a tendency to destruction during critical temperature fluctuations.

The basis of such structures is a centrifuged or vibrated rack made using dense heavy cement solutions reinforced with welded metal structures.

IMPORTANT: Special strength and durability are characterized by structures erected with the use of centrifuged racks (used for the device LPP 35-110 kV).

LEP supports, in addition to centrifuged and virgin racks, may consist of the following structural elements:

• subposses;
• consoles;
• reference and anchor plates;
• riglels;
• anchors for fixing the delay;
• lower concrete lid (spying);
• a wide spectrum of metal structures, including rope-bearing, traverses of extensions, head-glands, clamps, deficing, domestic connections, fastening nodes.

Installation of reinforced concrete supports in the soil is carried out by installing the structure in a pre-drilled cauldron of a cylindrical shape, followed by a sweeping of a sandy-gravel mixture into the sinuses formed.

In order to ensure the necessary strength of the construction of the structure on weak soils, the underground part of the BL support is strengthened by the riglels seized by half-womb. Clamps or through bolts are applied for attaching mounted metal structures.

Main characteristics

Retrootone supports are made using high-quality concrete reinforced with wire-rod and reinforcement rods.

Among the main advantages of these structures, the following qualities should be noted:

• affordable price, in comparison with all-metal analogues;
• corrosion resistance;
• resistance to long-term effects of chemical reagents;
• resistance to exposure to excessive humidity;
• resistance to temperature fluctuations.

Important: The main disadvantage of supports made using reinforced concrete is low strength in accordance with the mass of the construction as a whole.
In addition, high weight and dimensions of such products are wrapped with substantial spending during transportation.

Main varieties

In addition to the fact that reinforced concrete lighting supports are used everywhere, poles are used for power lines.

Such structures are divided into the following categories:

• Intermediate type supports - Used when arranging direct sections of the airline lines.

In the photo - intermediate types

Such structures are not designed for the load directed along the LAM and are used exclusively for the installation of wires and fixing cables. To date, about 80% of all LPPs are mounted on.

• Opports of anchor type Used in the arrangement of direct sections of the airlines route to provide transition through natural barriers or engineering facilities. Also, these pillars are widely used in those parts of the route, where it is necessary to change the number, brand and cross-section of the wires.

In the photo - Anchor Poles

• Support corners - Install in those areas where the track changes its direction. On the pillars of this type there are resulting loads of gravity of wires from inter-resistant adjacent spans.

If the route is characterized by a small angle of rotation (not more than 30 °), then the load on the supports are small, and therefore the angular intermediate supports can be used. At large angles, over 30 ° are used anchor corner supports with a stronger design and anchor mounting of wires.

• End support - This is a kind of anchor pillars.

Such structures are located predominantly at the beginning and end of the LAM. The structures of this type are designed for unilateral loads.

• Special supports Used to perform special tasks.

Construction features

In accordance with the structural features, reinforced concrete supports VL are divided into the following categories:

• portal with delay;
• portal with internal connections without delay;
• single and extinct with delay;
• one- and extinct without detentions.

Metal reinforced concrete support technology

So, after we have decided on the technical and operational characteristics of reinforced concrete supports intended for laying air lines, consider the technology of their manufacturing on the example of the modification of SV 95.

Instructions for production phased. The first - the preparatory stage provides for the following work.

Preparation of the working mixture:

• Preparation of Portland cement, inert materials, chemical. additives and water in accordance with the proportions given in the project documentation;
• Dosing of components and loading in a concrete mixer;
• Bringing the mixture to homogeneous consistency and unloading to the concrete-layer.

Preparation of reinforcing metal structures:

• Pruning reinforcement rods of the required class on the segments of the desired size;
• Preparation of anchor heads;
• Forming contour spirals;
• Formation of loops and preparation of the ground circuit rod.

Cooking forms:

• Cleaning the internal volume of the form;
• Lubrication of internal volume by means preventing adhesive concrete;
• Distribution of spirals;
• Carrying out isothermal heating of rods;
• The distribution of heated rods on pre-laid out stops;
• Production spirals between rods with subsequent mounting to rods at three points;
• Distribution of liners in the end of the form;
• Installation of tubes and technological loops with mandatory fixation to the inner surface of the formwork.

The second stage is production. At this stage, the filling of the working mixture is performed and the formation of the finished product.

The following works are performed during the process:

• Concrete-stage conveyor is installed in the working position and the prepared form is filled with a solution. Filling the form concrete is carried out by the movement of the stacker along.
• By means of a deep vibrator, a mixture seal is performed to prevent the formation of voids.
• Workers with their own hands through the rule or workshop equalize the surface of the laid material in the form.

In the third stage, the product is exposed to isothermal processing.

This is done as follows:

• The heat insulating material is placed on top of the filled formwork.
• The system of heating the internal formwork is activated. The system automatically controls temperature parameters, time, etc. Therefore, the influence of the human factor on the quality of the product is minimal.
• Purpose material is removed.

At the final stage, dismantling shape, trimming of reinforcement, quality check and shipment of the finished product to the warehouse.
