Cable textile sub tube

Abstract

A cable spinnerule belongs to the technical field of cable laying protection inner pipes, which is characterized in that the cable spinnerule has two or more than two reversed U-shaped unit channels which are folded by a polyester fabric, the longitudinal length of the reversed U-shaped unit channels extends indefinitely, and every arched shaped unit channel is superimposed with each other to formopen side edges which are sewed together. The cable spinnerule has new concept, rational structure, simple technology, high material utility ratio and low cost, and is suitable for various differentcable laying environment due to applying the cable spinnerule as the cable laying protection inner pipe, and not only can separate the penetrated cable, but also can reduce frictional loss of cable surface in the laying and stretching process, the most important is that the utility ratio of the channel is improved, the underground space and the outer pipe resources are saved, the material expenseis reduced, the project mass of the cable laying project is reduced efficiently, the project time is shortened , and the project expenditure is reduced.

Description

technical field [0001] The invention belongs to the technical field of cable laying protection inner tubes, and in particular relates to a cable textile sub-tube. Background technique [0002] In order to avoid the accumulation of cables and cable support devices on the ground, and to prevent the cables from being damaged by weather conditions, water and other environmental factors, optical fiber communication cables are generally laid through underground pipelines, and multiple cables need to be placed in the same pipeline. , in order to separate the cables placed in the same pipe and prevent the surfaces of the cables from rubbing against each other during the laying process, the traditional method is to put a group of hard protective inner tubes of different sizes into the pre-buried pipes. Put the cable into the hard protective inner tube, and only put one cable in the middle of each protective inner tube, and the inner diameter of the protective inner tube must be large...

AI Technical Summary

Problems solved by technology

However, the main structure of the existing soft cannula is that the two sides of the multi-layer flexible material layer are seamed to form corresponding channels. Generally, the flexible material layer needs to be braided or cut into long straight strips, and the width of each layer from the middle layer to the outside needs to be gradually increased. increase, and then all the flexible material layers are neatly aligned on both sides and then stitched. The process of weaving or cutting the flexible material layers into straight strips and sewing structures on both sides is relatively complicated, and the utilization rate of flexible materials is low, which increases the product cost. , In addition, the seam part reduces the smoothness of the interior to a certain extent, and one more seam line has a certain negative impact on the cable threading
