Abstract

The utility model relates to an underground communication cable direct-laying pipeline, which comprises a pipeline and pipeline connecting pieces. The pipeline is a multi-hole pipeline, the multi-hole pipeline is provided with a honeycomb-shaped cross-section which is composed of a plurality of circular rings which are tangential with each other, wherein the periphery of the honeycomb-shaped cross-section is surrounded by a plurality of circular arcs, and the pipeline is accompanied by identification. The pipeline connecting pieces which are matched with the pipeline are provide with a sleeve cylinder of a hole, wherein a shape of the sleeve cylinder is consistent with that of the periphery of the pipeline; a locating convex ring and a plurality of grooves are arranged in the hole along the circumferential direction; radial direction convex height of the convex ring is equal to wall thickness of the pipeline; the grooves are arranged at both sides of the convex ring, and sealing rubber rings are arranged in the grooves. The utility model has the advantages of compact structure, material saving, strong Sealing property, less construction procedure, and convenient maintenance management.

Description

The underground communication cable directly buried pipeline

The utility model relates to the pipeline of burying underground communication cable underground.

Burying the traditional pipe laying mode of underground communication cable has: one, at three polyethylene of the hole of underground cement block Φ 90 inner passing-setting pipe, and cloth communications optical cable in the son pipe, this scheme remains the cement pore and easily stops up, defectives such as seam crossing easy to leak, sinking, dislocation.Two, the method for the big effective big or small socket of per 6 meters one double-wall corrugated PVC material system is taken over; because big interface tube is many; its air-tightness and watertightness are relatively poor; only can play the mechanical strength protection and can't satisfy the requirement of protecting optical cable; so have in bassoon, wear the son pipe again; again optical cable is penetrated in the sub-pipe, with the protection optical cable.Obviously thisly need poling, wear the difficulty that the technology of cable has determined to wear cable again, from digging the cable ditch, to burying bassoon, wearing that son is managed, the well of conducting oneself (or hand hole), to wearing optical cable, construction schedule is obviously elongated again, and it is huge to pay wages.Three, five separate holes are set on the plastics cylinder, forming the five-hole tube road is laid in cement block Φ 90 holes, this pipeline has increased the reservation pore, can solve the problem that pipeline repeats to lay, thereby reduction project cost, but it still need be laid in the cement pore, increased difficulty of construction, this plastic conduit consumption material is many simultaneously, does not have in the process deposited, need cut off pipeline front end wearing and tearing section and also cause waste, in addition, this plastic conduit can only be made straight tube and can not coil, and does not also divide the cable positioning mark on the pipeline, the inconvenience operation, maintenance management.

In view of above-mentioned, the purpose of this utility model provides a kind of compact conformation, good airproof performance, and material consumption is low, and construction is simple, is convenient to maintenance management, inexpensive underground communication cable directly buried pipeline.

The underground communication cable directly buried pipeline that the utility model provides contains pipeline and conduit coupling, pipeline is void channels, it has by several annulus are tangent to each other and constitutes the cellular cross section that periphery surrounds for several circular arcs, the conduit coupling that cooperates with this pipeline is the sleeve that has with the hole of tube circumference shape kissing platform, circumferentially there are the protruding circle in location and some grooves in the edge in the hole, the radially protrusion height of protruding circle equates that with pipeline wall thickness groove is positioned at protruding circle both sides, and sealing rubber ring is set in groove.

Below in conjunction with accompanying drawing the utility model structure is described in further detail.

Fig. 1 is the utility model schematic diagram;

Fig. 2 is the cross section of a kind of concrete structure of pipeline of the present utility model;

Fig. 3 is the another kind of concrete structure cross section of pipeline of the present utility model;

Fig. 4 is the connector schematic diagram that is used for Fig. 2 pipeline;

Fig. 5 is the A-A cutaway view of Fig. 4.

The underground communication cable directly buried pipeline as shown in Figure 1, contain pipeline 1 and connector 2, pipeline is by the tangent void channels that constitute of several annulus, in instantiation shown in Figure 2, pipeline is the five-hole tube road, and it is to constitute by five annulus are tangent to each other that to have periphery be the cellular cross section that five circular arcs surround, perhaps also can be as shown in Figure 3, make three hole pipelines, constitute by three annulus are tangent to each other that to have periphery be the cellular cross section that three circular arcs surround.Usually, available macromolecule polymeric material, as PVC, PE, PP, an extrusion modling of thermoplasticss such as EVA, and make ring wall thickness that each annulus is positioned at the duct wall position greater than other position ring wall thickness of annulus, to guarantee saving material under the mechanical strength condition, this pipeline can coil, and therefore can make various different lengths according to the actual requirements.On each annulus of pipe end, scribble the differentiation color, so that really accurate each optical cable locus of living in pipeline, convenient branch cable, maintenance management.The conduit coupling that matches with five-hole tube shown in Figure 2 road as shown in Figure 4, the A-A cutaway view of Fig. 4 is seen Fig. 5, connector is the sleeve with the hole 4 that matches with the tube circumference shape, generally make connector appearance geometry identical with pipeline appearance geometry, circumferentially there are the protruding circle 5 in location and some grooves 6 in the edge in the hole 4 of connector, the radially protrusion height H of protruding circle equates with pipeline wall thickness, groove 6 is positioned at protruding circle 5 both sides, in the illustrated example, arranged two grooves respectively in protruding circle 5 both sides, this groove is used for the device sealing rubber ring, like this, connected two pipelines stretch in the connector, by protruding delineation position, and utilize the rubber ring in the groove to be sealed.

For further improving seal degree, also can be after pipeline stretches into connector, in connector two ends and the reusable heat plasticity sleeve pipe 3 (see figure 1)s sealing respectively of pipeline joint-seam place.

The pipeline configuration compactness that the utility model provides, material is economized, an extrusion modling of available macromolecule polymeric material, its resistance to compression, anti-ly open, crack resistance is good, can coil, it is strong to join the special connecting piece sealing, and the utility model need not sleeve pipe, can directly bury underground underground for the cloth optical cable, so working procedure is few, project cost obviously reduces, owing to have sign on the pipeline, then safeguards, manages very convenient.
