Problems solved by technology

Due to the rough cutting process of the steel pipe in this method, the encapsulated cable is easily scratched by the section, and there is a great potential safety hazard
It is also labor-intensive and labor-intensive to carry out pipe body connection and sealing and bandaging during construction.

Embodiment Construction

[0024] Such as image 3 As shown, the buried cable protective sleeve includes two sets of upper and lower semicircular tubes, and each set of semicircular tubes includes several sections of independent semicircular tubes. Such as figure 1 As shown, there is a flanging on both sides of each section of semicircular pipe 1, and these two flangings are respectively two types of flanging whose cross-sectional shape can be inserted into each other, wherein the cross-sectional shape of the first type of flanging 2 is outward Folded and then turned backwards, the cross-sectional shape of the second type of flanging 3 is to turn outwards, then forwards, then inwards and backwards. Such as figure 2 As shown, the upper group of semicircular tubes and the lower group of semicircular tubes are inserted together, the first type of flange 2 of the upper group of semicircular tubes is inserted into the second type of flange 3 of the lower group of semicircular tubes, and the first type of ...

Abstract

The invention relates to an underground cable protective sleeve which comprises an upper group of semicircular pipes and a lower group of semicircular pipes, wherein each group of semicircular pipes (1) comprise a plurality of segments of independent semicircular pipes, both ends of each segment of independent semicircular pipe are respectively provided with a flange, sections of the two flanges are respectively mutually inserted, the section of the first flange (2) is outwards turned and then backwards turned, the section of the second flange (3) is outwards turned, forwards turned and then inwards and backwards turned, the upper group of semicircular pipes and the lower group of semicircular pipes are mutually inserted together, joints (5) among the segments of the upper group of semicircular pipes and joints (6) among the segments of the lower group of semicircular pipes are mutually staggered, and the whole underground cable protective sleeve becomes a whole. When in use, the lower group of semicircular pipes are cushioned below an underground cable segment by segment and inserted into the upper group of semicircular pipes segment by segment until the whole underground cable is packaged by the underground cable protective sleeve, the underground cable protective sleeve has strong protective capability for the cable, the cable needs not to be cut, and the excavated earth volume is smaller.

Description

technical field [0001] The invention relates to a protective device for buried cables and optical cables, and a protective cover for buried cables. Background technique [0002] When constructing construction facilities such as roads, railways, oil pipelines, urban roads, water conservancy and electric power construction, it is often necessary to reinforce and protect underground communication cables. One method is to cut the cables and then re-route them and pass them through pipes for protection. This method is expensive, and needs to interrupt the communication service for cutover, which will affect the business. Moreover, when faults such as fiber breakage or cable air leakage occur in the protection tube, it will bring great difficulties to inspection and repair, and increase maintenance. cost. The other is to cut the steel pipe and wrap it to the outside of the cable. Due to the rough cutting process of the steel pipe in this method, the encapsulated cable is easily...
