Cable pipeline capable of being detected conveniently

Abstract

The invention provides a cable pipeline capable of being detected conveniently, which comprises a conductor and a pipe body used for installing a cable. The pipe body comprises an outer wall and an inner wall. Through holes are arranged abreast on the pipe body in the axial direction and penetrate through the outer wall and the inner wall, the conductor is arranged in the through holes. Therefore, when a section of the cable is damaged and has electricity leakage, the conductor at the position can be detected, and charge at the position can be detected to determine the specific position of damage and electricity leakage. The cable pipeline is convenient to operate, novel in structure, capable of avoiding construction cost increase caused by replacing the cable in a large scale and high in flexibility due to the fact that the distance between two through holes can be set.

Description

technical field [0001] The invention belongs to underground pipeline equipment, in particular to a cable pipeline, especially a cable pipeline which is easy to detect. Background technique [0002] The cable duct is an underground pipeline building used for the laying of cables. Compared with other cable laying forms, it has the following characteristics: [0003] Large capacity, multiple cables can be placed in the pipeline; pipe blocks can be laid symmetrically and overlapped, occupying a small underground section, which is conducive to the overall arrangement of other underground pipelines in municipal construction, while reducing overhead cables, which is conducive to beautifying the city; the pipeline can Reducing the direct damage of cables to external forces can further ensure communication security; even for pipelines that have been built for many years, the plane position and buried depth of the pipeline can be found according to drawings and data, which is convenie...

AI Technical Summary

Problems solved by technology

[0004] The cable duct detection is generally between two service stations, and the distance between the two service stations is generally long. Although it can be detected that there is a leakage or an open circuit in this section of the cable, it is not possible to determine exactly where it is Therefore, although a manhole is generally set at a certain distance for wiring, inspection, and maintenance, the length of the pipeline section (that is, the distance between the centerlines of two adjacent manholes) is generally set to be relatively long to save costs. Replacing cables on a large scale results in increased engineering costs and complex operations
