Combined cable protection pipe

Abstract

The invention discloses a combined cable protection pipe which is formed by an annular array of arc strip plates. Each arc strip plate is provided with a plug end and a plug fitting end peripherally,wherein the plug end is peripherally provided with a fixing head in an extending manner, and the plug fitting end is provided with a fixing groove matched with the fixing head. The combined cable protection pipe is structurally characterized in that upper and lower walls of each fixing groove are provided with locking blind holes, and each fixing head is internally provided with a grouting hole extending along the center axial direction and is provided with a through hole which is matched with the corresponding locking blind hole and penetrates from the surface of the fixing head to the grouting hole. Compared with the prior art, the combined cable protection pipe has advantages that reasonable design and simple structure are realized; during mounting, step-by-step mounting is performed tofinally form an intact protection pipe, so that the problem of taking out buried cables in mounting is avoided, construction efficiency is improved, steady protection is realized, and the problem ofbursting of the protection pipe in heat swelling of the cables can be avoided.

Description

technical field [0001] The invention belongs to the field of pipes, and in particular relates to a combined cable protection pipe. Background technique [0002] At present, cables are widely used communication and electrification equipment, and their application places are different, some are used underwater, some are used underground, but their application environment will cause certain damage to the cable itself, so it is necessary to Set up the protection tube. [0003] In the prior art, the invention patent (application number: 201820065525.7) discloses a structural wall pipe for power cable protection pipe, which forms a complete protective pipe after the first pipe body and the second pipe body are butted and matched, but there is a problem of incomplete connection. The problem of stability, as we all know, when the power cable conducts electricity, the temperature of the cable itself will rise due to resistance, which will cause expansion. Although the expansion is n...

[0003] In the prior art, the invention patent (application number: 201820065525.7) discloses a structural wall pipe for power cable protection pipe, which forms a complete protective pipe after the first pipe body and the second pipe body are butted and matched, but there is a problem of incomplete connection. The problem of stability, as we all know, when the power cable conducts electricity, the temperature of the cable itself will rise due to resistance, which will cause expansion. Although the expansion is not large, it will still separate the pipe body and the pipe body. A gap is formed between the two, which even leads to the separation of the first pipe body and the second pipe body, thus losing the protective effect on the cable, and if the expansion is reserved during installation, then the contact between the protective tube and the cable will not be close enough. loss of protection
