Abstract

The utility model discloses an underground communication pipeline skeleton type separated fan-shaped secondary pipe, particularly a skeleton which is arranged in the original circular pipe hole for replacing the arrangement of a plurality of secondary pipes in the pipe hole. The utility model is composed of a skeleton and separating plates, wherein the separating plates use the skeleton as a centre and radiate outwards in a circular mode, the separating plates are arranged in the original circular pipe hole, and a plurality of fan-shaped secondary pipes are formed from the separating plates and the pipe hole. Thus, the formed fan-shaped secondary pipes make the effective inner diameter in the secondary pipe largest. When a cable is penetrated, compared with a circular pipe which has the same inner diameter, the utility model has a larger residual space. The utility model is suitable for different inner diameters of pipe holes of cement pipelines and plastic pipelines, a second cable can be penetrated, the utilization rate of the secondary pipe is increased, and other circular secondary pipes are not analogous with the utility model. Meanwhile, because the outer wall of the pipe hole is used as the pipe wall of the secondary pipe, materials are saved, the space is sufficiently used, and the structure is simplified.

Description

The skeleton separated sector subpipe of underground communication pipeline

Affiliated technical field

The utility model relates to the skeleton separated sector subpipe of a kind of underground communication pipeline, and specifically a kind of skeleton of installing forms fan-shaped son pipe in former pore, replaces many roots pipe, communication pipe technical field under the possession.

Background technology

At present, wearing the sub-pipe of putting in the communication pipe has two kinds, and a kind of is complicated-shape porous son pipe (plum blossom pipe), and another kind is to wear after three or the five root pipe bundle combinations to be placed in the pore, and the problem of existence is: the pore utilance is low, causes conduit resource to waste; Sub-bore is little, makes medium logarithm cable and big core count optical cable and can't wear and put; Can't realize the pore classification; Can't select and the suitable child pipe of putting of cable external diameter of wearing, because of the underground utilities resource non-renewable, in case be difficult to rebuild when not satisfying demand, and prior art, material can't make the pore utilance reach maximization, make line resource be not fully utilized.

The utility model that I applied in 1998 " communicating by letter with porous plastics pipe and tube connector " (ZL 982 47593.4) is though solved the problems referred to above, but be only applicable to newly-built communication pipe, sub-bore and sub-hole count that new pipeline builds up the back antipriming pipe are unmodifiable, which kind of pore choosing is established and is truly had certain degree of difficulty when inaccurate or unpredictable for requirement forecasting, can't make the old pipeline coupling use in new ducted antipriming pipe and single aperture.

Summary of the invention

Use back pore utilance low in order to overcome above-mentioned son pipe, sub-pipe can not classification; Can't mate with the pipeline of antipriming pipe cohort.The utility model provides fan-shaped porous of the skeleton separation of a kind of underground communication pipeline pipe, and the optical cable that it can be fit to following cable of medium logarithm and large and small core number uses, and improves the pore utilance; Realize porous classification and single hole classification, make new and old pipeline coupling.

The technical scheme that the utility model technical solution problem is taked is: the skeleton separated sector subpipe of packing in former pipe hole, it is made up of skeleton and separating plate, a plurality of separating plates are arranged on the skeleton, by the outside rounded radiation of frame center, this skeleton is packed in the former pipe hole, a plurality of big with its formation, little identical or big, little different fan-shaped son pipe, so the fan-shaped sub-pipe that forms can make effectively internal diameter maximization in the son pipe, wear put a cable after, than same inner diameter pipe bigger remaining space is arranged, can wear and put the second cable, the utilance of sub-pipe is improved greatly, is that any kind of circular son pipe is inaccessible, utilizes former pipe hole outer wall to be child pipe pore wall simultaneously, not only saved material but also make full use of the space, simplified structure.

The beneficial effects of the utility model are: the sub-bore that has solved present use is too small, and medium logarithm cable, big core are counted optical cable and can't be worn the problem of putting, and raising pore, son pipe utilance realize the pore classification, realize the use of new and old pipeline coupling.
