Line pipe supporting device for underground pipe gallery and mounting method of line pipe supporting device

Abstract

The invention relates to a line pipe supporting device for an underground pipe gallery and a mounting method thereof, and relates to the field of underground pipe galleries, the line pipe supporting device comprises a telescopic piece, one end of the telescopic piece is connected with a supporting assembly, the supporting assembly comprises a mounting plate used for abutting against the inner wall of a line pipe, and the surface, used for abutting against the inner wall of the line pipe, of the mounting plate is provided with at least one sliding groove; a sliding groove is formed in the mounting plate, a sliding plate used for being attached to the inner wall of the spool is slidably connected into the sliding groove, a control assembly for controlling the sliding plate to move in the length direction of the mounting plate and in the direction away from the mounting plate is connected to the mounting plate, a plurality of substitute plates tightly abutting against the bottom face of the sliding plate are arranged in the sliding groove, and an elastic piece is connected between each substitute plate and the bottom wall of the sliding groove; when the sliding plate slides along the sliding groove until the sliding plate is separated from the substitute plates, the substitute plates move in the direction away from the bottom wall of the sliding groove under the acting force of the elastic pieces. The method has the effect of prolonging the service life of the wire pipe.

Description

technical field [0001] The present application relates to the field of underground utility tunnels, in particular to a line pipe support device for underground utility tunnels and an installation method thereof. Background technique [0002] The underground pipe gallery is also called the underground comprehensive pipe gallery, that is, a tunnel space is built underground, which integrates various engineering pipelines such as power, communication, gas, heating, water supply and drainage, and has special inspection ports, hoisting ports and monitoring System, the implementation of the same planning, unified design, unified construction and management of important infrastructure. [0003] In the related art, long line pipes are usually arranged in the pipe gallery. In order to install the line pipes in the pipe gallery more stably, a support device will be set in the line pipe at intervals. The support device is used to align the line pipe inner wall for support. [0004] T...

AI Technical Summary

Problems solved by technology

[0004] The supporting device supports the wire pipe by touching the inner wall of the wire pipe. During the process of the supporting device touching the inner wall of the wire pipe, the supporting device may suddenly give a large supporting force to the inner wall of the wire pipe, and the wire pipe may be damaged. Makes the service life of the line pipe shorter
