Water supply pipe buttress with functions of height adjustment, shock absorption and electrochemical corrosion in pipe gallery

Abstract

The water supply pipe buttress comprises a buttress lower block, a buttress upper block and a plurality of height adjusting supports, the buttress lower block, the buttress upper block and the height adjusting supports are arranged in the pipe gallery, the buttress lower block is a horizontally-arranged cuboid-shaped supporting body, and the bottom of the buttress lower block is fixed to a pipe gallery body; the buttress upper block is a horizontally-arranged block body and is located above the buttress lower block, and the distance between the buttress upper block and the buttress lower block is adjustable; the upper part of the buttress upper block is used for supporting and bearing a water supply pipeline; the height adjusting supports are vertically arranged between the buttress lower blocks and the buttress upper blocks, and the upper ends and the lower ends of the height adjusting supports are connected with the corresponding buttress upper blocks and the corresponding buttress lower blocks; and all the parts can extend upwards or shorten downwards. When differential settlement of the buttress occurs, the relative height between the adjacent buttress upper block and buttress lower block is adjusted, so that the buttress upper block is located at the initial spatial position, the buttress upper block supports the water supply pipe and enables the water supply pipe to be evenly stressed, and therefore the purpose of reducing uneven stress of the water supply pipe caused by differential settlement of the comprehensive pipe gallery is achieved.

Description

technical field [0001] The invention belongs to the technical field of comprehensive pipe gallery, and in particular relates to a water supply pipe support pier in the pipe gallery with height adjustment, shock absorption and electrochemical corrosion. Background technique [0002] The comprehensive pipe gallery is a comprehensive corridor of underground urban pipelines, that is, to build a tunnel space underground in the city, integrating various engineering pipelines such as power, communication, gas, heating, water supply and drainage, etc., with special inspection ports, hoisting ports and The monitoring system, which implements unified planning, unified design, unified construction and management, is an important infrastructure and "lifeline" to ensure the operation of the city. [0003] With the development of the comprehensive pipe gallery, more and more water supply pipes are erected in the urban underground comprehensive pipe gallery by using piers. Compared with t...

AI Technical Summary

Problems solved by technology

Compared with the previous buried water supply pipelines, although the water supply pipelines erected in the urban underground comprehensive pipe gallery are not affected by earth pressure and soil corrosion, they are still subject to the following three potential hazards: ( 1) Due to the uneven settlement after the construction of the pipe gallery, the erected water supply pipeline will subsequently settle, causing uneven force on the pipeline and causing the pipeline to disengage at the welding position

(2) For the pipe gallery built near the subway, the water supply pipe will also be affected by the vibration of the subway, which will cause the water flow in the pipe to shake, causing certain safety hazards

(3) There are other power, communication, gas and other pipelines in the pipe gallery, and the water supply pipes will cause electrochemical corrosion due to the stray current in these pipelines, which will bring serious damage to the normal operation of the water supply pipes in the comprehensive pipe gallery. security threat

Once the pipeline is erected, if it encounters the above-mentioned hazards such as uneven settlement, vibration impact, and electrochemical corrosion, it will face the problems of heavy workload, high difficulty, and high cost for rectification
