Pipe for cable laying and producing method thereof

Abstract

The invention provides a cable laying conduit which has a simple structure and superior productivity, and through which a plurality of cables can be laid easily and satisfactorily. A wall forming material (3), on which a plurality of cable laying passages (2), (2), etc., approximately in parallel with each other are integrally formed, is wound into a cylindrical shape so as to have the cable laying passages (2), (2), etc., directed in the axial direction of a conduit to form a cable laying conduit (1).

Description

technical field [0001] The present invention relates to a pipe for cable laying and a manufacturing method thereof for laying cables such as optical fiber cables, electric wires and cables, for example. Background technique: [0002] In the past, fiber optic cables and wires and cables were put into the pipes by using the laid upper and lower water pipes, etc., and when they were put in, the automatic laying devices that had been inserted into the cables were inserted into the pipes. The flexible cable laying pipe is fastened above the inner wall of the installed pipe. [0003] As a conventional pipe for laying cables, it is constructed by binding several pipes together, wrapping the outer circumference with a wire, and inserting the cables into each pipe so that the several cables are not entangled with each other, and then It can be put into the pipeline that has been laid. [0004] However, such a cable laying pipe has a complex structure and poor productivity. In addit...

AI Technical Summary

Problems solved by technology

[0004] However, such a cable laying pipe has a complex structure and poor productivity. In addition, due to the influence of factors such as tension and bending during laying, the bundled pipes are prone to misalignment. When the cable is put into the pipe, there will be obstacles, or the cable in the pipe will be twisted, and excessive force will be applied.
