Color system sub-tube branching device for integrated pipe corridor communication pipe and installation method thereof

Abstract

The invention belongs to the field of integrated pipe corridor engineering communication engineering of an urban underground pipe network system and relates to a color system sub-pipe branching devicefor an integrated pipe corridor communication pipe and an installation method thereof. The device comprises a reserved PVC pipe, and two ends of the reserved PVC pipe are equipped with a sealing flange, a positioning sleeve and a seven-color sub-tube. A limiting convex ring is inwardly formed from the inner edge of a side end part of the sealing flange away from the reserved PVC pipe, and a groove is formed between the limiting convex ring and an inner wall of the sealing flange. A positioning sleeve is embedded in the groove, and a receiving groove for receiving an end part of the seven-color sub-tube is made in the positioning sleeve. The seven-color sub-tube comprises an outer sleeve tube, and seven inner sleeve pipes uniformly pass the internal part of the outer sleeve tube. The seveninner sleeve pipes are hollow and are used for passing communication cables. The outer edges of the seven inner sleeve pipes are in contact with each other to form an integral inner tube, two side end parts of the inner tube extend from two ends of the outer sleeve tube, and one end part of the inner tube is embedded in the receiving groove made in the positioning sleeve.

Description

technical field [0001] The invention belongs to the communication engineering field of a comprehensive pipe gallery project of an urban underground pipe network system, and relates to a color system sub-pipe branching device and an installation method thereof for the communication pipe arrangement of a comprehensive pipe gallery. Background technique [0002] At present, the communication cables in the comprehensive utility gallery project are usually laid in the reserved communication pipes, and the pipe diameters are generally 110mm PVC pipes. After the main acceptance of the pipe gallery is passed, various pipelines such as China Mobile, China Unicom, China Telecom, and cable TV are laid in the communication pipes. In order to distinguish the ownership units of the communication cables, the communication lines of each unit are often bundled. The cables are laid separately in bundles in the communication pipe. [0003] Through engineering practice, it is found that variou...

AI Technical Summary

Problems solved by technology

[0003] Through engineering practice, it is found that various cables in the communication pipes in the prior art are mixed, and the identification is laborious. It is difficult to repair cables in the later operation and maintenance of the comprehensive utility gallery, including the difficulty of adding pipelines and extracting them for maintenance.
