Abstract

The utility model relates to a flexible porous pipe and belongs to the technological field of inner pipes that are used for protecting the laying of cables. The flexible porous pipe is characterized in that one side of annular polyester fabrics is folded to form two or more than two inversed U-shaped unit channels; the other side is provided with a single inversed U-shaped unit channel. The length of the inversed U-shaped unit channels (1) and the single inversed U-shaped unit channel can be extended infinitely; the overlapping parts of the inversed U-shaped unit channels (1) and the single inversed U-shaped unit channel are spliced. The flexible porous pipe has the advantages of novel conception, reasonable structure, simple process, high utilization rate of manufacturing materials, and low manufacturing costs. The adoption of the flexible porous pipe in the laying of cables as the protective inner pipes not only can separate different cables on the same pre-buried pipeline, but also can reduce the frictional damage to the surface of the cables in the laying and drawing process. Moreover, the flexible porous pipe has the beneficial effects of fully improving the utilization rate of the pipeline, saving the underground space, saving the resources of outer pipes, reducing the costs of materials, adapting to bending pipelines and other different laying environments, and so on.

Description

Flexible antipriming pipe

Technical field

The utility model belongs to Manifold technology field in the cable laying protection, is specifically related to a kind of flexible antipriming pipe.

Background technology

For avoiding assembling on the ground the bracing or strutting arrangement of cable and cable; and avoid being subjected to various meteorological conditions; the damage of water and other factor; optical telecommunications cables etc. are generally all laid by underground piping; need to lay many cables in the pipeline; for the cable that will be laid in the same pipeline is separated; prevent cable surface phase mutual friction in the process of deployment; traditional method is that pipe in one group of hard protection not of uniform size is penetrated in the pre-buried pipeline; again cable to be spread is penetrated in the interior pipe of hard protection; wear in the middle of the pipe in each root protection and put a cable; the internal diameter of pipe must be bigger than wearing payout external diameter in the protection, and is impaired to prevent the cable surface friction.In this case; have the dead band between the pipe in the hard protection in the pre-buried pipeline, there is waste in the inner space of pipe in the protection, and these have all caused the space availability ratio of pre-buried pipeline to reduce; thereby increase the pipe laying cost, comprise increase pipe diameter, bury etc. the excavation shop again.Unavoidably bend can occur in the cable laying in addition,, adopt in traditional cable hard protection pipe to wear and put, can only cable not isolate, safeguard measure directly do not pass as the zone that needs to adopt many crooked pipelines at building access point etc.Use the problem that pipe exists in the hard protection in the current cable process of deployment for overcoming; at present existing flexible cannula is designed and developed and is come into operation; and obtained good effect; guaranteeing under the prerequisite that cable is cut apart; obviously save the space of pre-buried pipeline; but being layer flexible material layer both sides, existing soft intubate primary structure sews up the corresponding passage of formation; generally need be with flexible material layer braiding or cutting growth vertical bar; and outwards progressively increase of the width of each layer from the intermediate layer; sew up after again all flexible material layer two avris being aligned; the technology that structure is sewed up in flexible material layer braiding or cutting growth vertical bar and both sides is relatively complicated; the utilance of flexible material is low; product cost is raise; sew up the position in addition and reduce inner smoothness to a certain extent, many seam pair of connecting wires are worn payout and are had certain negative effect.
