Concrete pole for electrical networks: installation, installation and control
Today humanity cannot imagine existence without electricity. An uninterrupted supply of electricity to each room depends on the competent laying of networks from directly to each consumer. This goal led specialists to the invention of reinforced concrete electric poles. The devices do their job very well. Before starting work, you should calculate how much the materials cost and how long the installation will take.
Before making an electric pole, it is necessary to take into account the advantages of such supports. The advantages include durability. Reinforced concrete electric poles can serve consumers for many years. It is important to take into account that high-quality building materials should be used in the construction of supports. They are more expensive, but their use guarantees durability to each concrete pillar.
Another plus is the choice of design. With the help of additional building materials (panels and other means), you can arrange. In addition, during installation work, specialists will not need expensive special equipment. This allows you to do the installation yourself and not turn to professionals.
How many disadvantages do such supports have? A concrete pole for electricity has only one drawback. We are talking about laying the foundation, which is necessary in order to securely install a reinforced concrete electric pole. Otherwise, the structure may fall.
Application
- power lines;
- street lighting electrically;
- transmission of electricity.
Installation
When installing an electric concrete pole, it is important to observe a number of conditions. First of all, builders must take into account the landscape, the strength of the wind gusts in the region, the traffic density of cars. Also, specialists should measure the distance between reinforced concrete supports. It is necessary to determine how many meters there are between each pillar. During installation work, a thorough check on the strength of the supports is carried out.
Execution of work
For uninterrupted transmission of electricity, it is necessary to install a structure in accordance with safety regulations. For the correct construction of supports, builders should adhere to the following rules:
- install poles depending on the purpose, terrain features and laying, special equipment systems;
- perform high-quality installation work;
- fix the wires on the poles according to all the rules (PUE).
Each reinforced concrete support is installed in stages:
- First you need to mark the selected territory.
- Then the specialists begin drilling holes for the poles.
- After that, you can start installing the supporting structures. For this, special equipment is used.
- The last stage is the installation of electrical wires.
Selection and marking of the territory
For proper installation of concrete structures, it is necessary to adhere to safety rules. In particular, the marking of the selected territory involves choosing the place for erecting supports and determining the distance directly between the pillars.
The calculations should take into account the expected loads, as well as the characteristics of a particular area and soil. The markup should be done in such a way that as a result, uniform illumination of the areas by each pillar is achieved. Specialists carry out installation according to the technology of installation work. When marking, the number of concrete pillars and their location are determined.
Drilling
After marking is completed, specialists begin drilling, following the marked parameters and taking into account the characteristics of the soil at the installation site. At this stage of work, a technique is used, which is a drill placed on a special platform.
Installation of reinforced concrete pillars
Before starting work, it is necessary to recheck the supporting structures for possible cracks. Their vertical alignment is carried out using special levels and other means. A manipulator is used to erect concrete pillars. A thick cement mortar is poured into each pit where the supporting structures were installed. To give structures additional stability, specialists install props made of reinforced concrete or metal.
Work control
When installing and assembling support structures, you must carefully monitor the strict observance of the parameters:
- Measurement of a pit intended for reinforced concrete supports. For reliable installation, the design of the pit must be deep.
- The quality of the material from which the structure is made. If the reinforcement is visible and cannot be covered with concrete, the product will soon begin to collapse.
- Specialists must install metal spacers in a dug hole in the place where the post is in contact with the ground. The Zeta workers should cement the support structure with high quality cement mortar.
- Specialists need to install the structures in a strictly vertical position using a special plumb line.
The final stage is the laying of electrical wires.
After the installation is completed, the installation of metal structures for attaching insulators begins. For this, clamps are used. There are also traverses that are not intended to transmit current. They are only needed to secure the electrical wires. Their dimensions will depend on the number of electrical wires that they have to hold.
To prevent possible corrosion of the traverses, it is necessary to cover them with a special agent that will ensure their protection. In addition, experts fix a cover that will protect them from the harmful effects of the environment. The laying is completed with the installation of electrical wires. At the same time, workers should take into account that the above actions must be carried out by representatives of an organization that has the appropriate permission.
Conclusion
Work on the installation of reinforced concrete structures for power lines is a responsible and complex process that involves the use of special equipment. If workers take into account the prescribed rules and safety precautions, they will be able to build a reliable and durable structure. Such a support will transmit electricity uninterruptedly for many years.
It is also important to remember that installation work should be carried out by employees of organizations with the appropriate permit.
