Abstract

The utility model belongs to the auxiliary of underground communication optical cables, relating to the technical proposal of the improvement of a communication optical cable protective sleeve. A porous tube with identifying colour layers comprises more than two circular pipes stretching axially. The circular pipes are distributed in a central emissive shape. Two adjacent circular pipes are crossed. The utility model is characterized in that the outer wall surface of at least one circular pipe is covered with an identification colour layer axially. With the utility model can, through the improvement of the structure of the outer wall surface, pipelines and cables can be easily identified under a plurality of conditions. The utility model has the advantage of convenient construction and maintenance.

Description

A kind of antipriming pipe with identifying colour layer

The utility model belongs to underground communication optical cable auxiliary, relates to the improvement technical scheme of communications optical cable protective casing.

At present, concrete pipe is mainly adopted in the pipeline laying of underground communication optical cable, interior a plurality of PVC of cover or PE pipe are worn the mode of cloth communications optical cable again, and are adopted the antipriming pipe technical schemes of a plurality of son pipe one in the sub-pipe, compact conformation, easy construction, but still have the some shortcomings part, as cutting pipe or pipeline maintenance in the pipeline laying process, when safeguarding, often need come in proper order to determine concrete cable by the identification pipeline, but prior art, only distinguishing mark is arranged, can't satisfy actual needs in the homogeneous tube end.

The objective of the invention is to overcome the deficiencies in the prior art part, by the improvement of circular tube external wall surface structure, convenient construction and safeguard time identification pipeline and cable provides a kind of improvement technical scheme of antipriming pipe.

The objective of the invention is to be achieved through the following technical solutions, a kind of antipriming pipe with identifying colour layer contains the pipe that axially stretches more than two, pipe is the center emitting shape and distributes, adjacent two pipes intersect, and it is characterized in that having at least a circular tube external wall, are covered with identifying colour layer vertically.

Described a kind of antipriming pipe with identifying colour layer overlays on that identifying colour layer comprises the epoxy chromatograph of internal layer and the gloss oil layer on top layer on the tube wall.

Described a kind of antipriming pipe with identifying colour layer, pipe is isometrical, presses the regular polygon orientation and distributes.

Described a kind of antipriming pipe with identifying colour layer is distributed with the bar ditch that extends vertically on the pipe inside surface, the bar ditch is straight long shape or bending.

Described a kind of antipriming pipe with identifying colour layer, the section edges contour shape of bar ditch are corrugated or flat profile of tooth.

Described a kind of antipriming pipe with identifying colour layer, the intersection of adjacent two pipes are the width riglet identical with the pipe wall thickness.

Described a kind of antipriming pipe with identifying colour layer is by the extrusion molding of macromolecule polymeric material one.

The utility model by the outer wall surface architecture advances, under multiple situation, is all discerned pipeline and cable easily, and convenient construction and maintenance have good practical value.

Further specify the utility model and provide embodiment below in conjunction with Figure of description.

Fig. 1: the utility model structural representation.

Fig. 2: the utility model partial sectional view.

A kind of antipriming pipe with identifying colour layer as described in Figure contains five isometrical pipes 1, and pipe 1 is pressed the regular polygon orientation and distributed, and adjacent two pipes, 1 tube wall intersects in twos.Have at least the outer wall of a pipe 1 that identifying colour layer 3 is arranged vertically again, identifying colour layer 3 comprises the epoxy chromatograph 4 of internal layer and the gloss oil layer 5 on top layer, and identifying colour layer 3 overlays on the outer surface of tube wall, can add bonding coat between epoxy chromatograph 4 and the outer surface of tube wall.This identifying colour layer 3 can cover pipe 1 whole outer surface, also can be a ribbon composite bed, is convenient to after any place cuts pipe, and truncated end still has distinguishing mark, can make workmen or maintainer discern pipe 1 order and concrete cable relatively.Pipe 1 inside surface is distributed with vertically the bar ditch 2 that extends, and bar ditch 2 linearly or curve-likes, the section edges contour shape of bar ditch 2 are level and smooth corrugated, also can be flat profile of tooth.Pipe 1 is through improving, and optical cable and inside pipe wall surface of contact reduce greatly, and frictional resistance is corresponding during perforation reduces greatly, and the bossing smooth transition of bar ditch 2, also can not damage optical cable.The intersection of adjacent two pipes 1 is width and the identical riglet of pipe 1 wall thickness.Promptly easy to process, save material again, can guarantee that tube wall does not penetrate simultaneously, under identical outer tube diameter situation, improved internal orifice dimension.This antipriming pipe is by the extrusion molding of macromolecule polymeric material one.
