Abstract

The utility model relates to an optical cable textile son tube and is characterized that the optical cable textile son tube is provided with O-shape unit channels which are woven by polyester textile or aramid fiber with a changeable longitudinal length; hauling cables are matched and arranged in the O-shape unit channels; the mutually-overlapped neighboring sizes of the O-shape unit channels are of independent structures; two or more than O-shape unit channels are woven along a central line or the parallel line of the central line to form a plurality of independent channel units. The optical cable textile son tube has the advantages that: the O-shape unit channels can be woven along the central line or the parallel line of the central line; two or more than two O-shape unit channels can also be overlapped and woven by adopting the method, and can be divided into more than three independent tube cavities; and each independent tube cavity can hold one hauling cable. The optical cable textile son tube has the beneficial effects of reasonable structure, simple technique, high preparation material utilization rate, and low manufacture cost, not only can separate different optical cables in the same embedded pipeline, but also can reduce the friction damage of the surfaces of the optical cable during paving and hauling, which sufficiently improves the utilization rate of pipelines, and is suitable for various paving environments like bent pipelines, etc.

Description

The optical cable textile sub tube

Technical field

The utility model relates to a kind of optical cable textile sub tube.Belong to Manifold technology field in the optical cable laying protection.

Background technology

For avoiding assembling on the ground the bracing or strutting arrangement of optical cable and optical cable; and avoid being subjected to various meteorological conditions; the damage of water and other factor; optical-fibre communications optical cable etc. is generally all laid by underground pipeline; need to lay many optical cables in the pipeline; for the optical cable that will be laid in the same pipeline is separated; prevent optical 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 optical 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 an optical cable; the internal diameter of pipe must be bigger than the wear cable external diameter of giving out light in the protection, and is impaired to prevent the optical cable mantle 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 pipeline laying cost, comprise increase pipe diameter, bury etc. the excavation shop again.Unavoidably bend can appear in the optical cable laying in addition; as the zone of adopting many crooked pipelines at needs such as building access points; adopt traditional interior pipe of optical cable hard protection to wear and put, optical cable directly passes without isolation, safeguard measure, has caused the aging of optical cable and has destroyed.Use the problem that pipe exists in the hard protection in the optical cable laying process 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 optical 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 middle 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 utilization factor of flexible material is low; cost of products is raise; sew up the position in addition and reduce inner smoothness to a certain extent, many seam pair of connecting wires are worn the cable of giving out light and are had certain negative effect.

Summary of the invention

The utility model aims to provide the optical cable textile sub tube that a kind of rational in infrastructure, technology is simple, material is saved, to overcome existing above-mentioned defective in the prior art.

Technical solution of the present utility model: the longitudinal length that it is characterized in that having an O shape unit channel that is compiled into by polyester textile or aramid fiber material is variable, be equipped with traction rope in the O shape unit channel, the adjacent edge of the O shape unit channel that is superimposed with each other is an absolute construction, and two or more O type unit channels are made a plurality of independent O-shaped unit channels of formation along center line or center line parallel lines.

Advantage of the present utility model: novel, the rational in infrastructure and technology of this optical cable textile sub tube is simple, manufacturing materials utilization factor height, low cost of manufacture; adopt optical cable textile sub tube disclosed in the utility model as pipe in the protection in the optical cable laying; different optical cables in the same pre-buried pipeline can be separated; can in laying tractive, reduce optical cable mantle friction damage again, the more important thing is and fully to improve the pipeline utilization factor, save the underground space, save the outer tube resource, reduce Master Cost and adapt to beneficial effects such as various laying environment such as crooked pipeline.

Description of drawings

Accompanying drawing 1 is the structural representation of optical cable textile sub tube;

Accompanying drawing 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7 are respectively the structural representation of embodiment 1-6;
