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

Embodiment Construction

[0013] The present invention will be further described below in conjunction with accompanying drawing of description:

[0014] The flexible porous tube is a ring-shaped polyester fabric that is folded on one side to form two or more ∩-shaped unit channels 1, and the other side forms a single ∩-shaped unit channel 1a. The ∩-shaped unit channel 1 and the single ∩-shaped unit channel 1a The longitudinal length continues indefinitely, and the overlapping parts of the ∩-shaped unit channel 1 and the single ∩-shaped unit channel 1a are sewn together by the seam line 2, so that each ∩-shaped unit channel 1 and the single ∩-shaped unit channel 1a are respectively sewn into a closed channel, and the flexible porous tube The longitudinal length of the cable can be cut according to the needs of the site, and a cable is placed in each channel to separate and protect the cables. Each ∩-shaped unit channel 1 and a single ∩-shaped unit channel 1a are respectively equipped with a traction rop...

Abstract

A flexible porous pipe belongs to the technical field of cable laying protection inner pipes. It is characterized in that one side of a ring-shaped polyester fabric is folded to form two or more ∩-shaped unit channels, and the other side forms a single ∩-shaped unit channel. The longitudinal length of the ∩-shaped unit channel (1) and the single ∩-shaped unit channel Infinite continuation, ∩-shaped unit channels and overlapping parts of single ∩-shaped unit channels are stitched together. The flexible porous tube has a novel concept, reasonable structure, simple process, high material utilization rate, and low manufacturing cost. The flexible porous tube disclosed in the present invention is used as the protective inner tube in cable laying, and can be applied to various cables. The laying environment can not only separate the cables that are threaded, but also reduce the friction damage on the cable surface during laying and pulling. More importantly, it can fully improve the utilization rate of pipelines, save underground space, save outer pipe resources, and reduce material costs. Effectively reduce the engineering quantity of the cable laying project, shorten the construction period, and reduce the project cost.

Description

technical field [0001] The invention belongs to the technical field of cable laying protection inner tubes, and in particular relates to a flexible porous 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...
