Telephone sewerage - how is it design ?

Purpose and types of telephone conduit

The main purpose of the sewerage system is adequate protection and plastic leaded wire of all kinds of mechanical damage.Also can be protected additional cables and without having to dig up the ground again.And there is a certain proportion of the benefits and cost savings, as the wires are laid in the telephone conduit, easier to operate than those that are located in the ground (armored).

If we talk about these kinds of sewage system, it is divided into:

• Junction.
• bandwagon.

Distribution mounted directly to racks and cabinets buildings and cable distribution posts.For competent installation and repair of the system makes special wells.The distance between the wells sewage is about 1.5 meters, and place them at the point of branching and turning the pipe.

each well dimensions depend on the number of cables placed inside.Wells are classified as directed to: continuous, stationary, branching.Also, wells are classified by material from which they are made on the brick, and reinforced tselnonabivnye.

main types telephone conduit device implies the presence of a stationary pit from which the branching in different directions.However, each line must be attached to the control cabinet.In these kinds of sewage usually stretch connecting and main cables.

Design telephone conduit

Before the construction will be carried out telephone conduit, carefully prepared project.The project shall include: the route for laying the pipeline (the shortest), the minimum number of obstacles, the minimum cost to protect pipelines from electricity, the maximum number of mechanisms that are used during installation, the minimum distance from the railways, creating better conditions for the operation of sewage.

important condition in the design is also the security and reliability of cable lines.It determines this readiness coefficient Kr, which should not be more than 0.9996.This figure is calculated on the protection of wires from a lightning strike.Determine the number of grounding devices and material.

The main purpose of the calculations - the definition of the most accurate data for the proper operation of the system in the future.Therefore, the project should be prepared by professionals.sewage supply is the best installers.

teleinspection sewage

After drainage built and is in operation, can be teleinspection sanitation.This method is an internal observation with a special video equipment.

Video equipment - a mini camera that can move completely freely within the tubes and send a fairly clear picture on the operator monitor.The image is saved and can be viewed at any convenient time.Such monitoring is carried out for:

• Identifying blockages formed.
• Definitions cracks and damages, as well as monitor the walls and joints of pipes.
• control illegal incisions other pipes.
• evaluate and verify the level of construction works.

This inspection allows you to track the current state of the sewage system and to provide timely technical support.Thus, high-quality repair done without adverse effects.
