City underground comprehensive pipe rack overhauling method

Abstract

The invention relates to a city underground comprehensive pipe rack overhauling method which comprises the steps of before casting a pipe rack bottom plate, binding reinforcing steel bars of the piperack bottom plate, then paving two rows of tracks above, welding the tracks on the reinforcing steel bars of the pipe rack bottom plate, and orderly docking the tracks between two adjacent sections ofpipe racks, wherein a joint is not larger than 5mm; arranging an overhauling vehicle on the tracks, wherein the speed of the overhauling vehicle can be adjusted, and the maximum speed is 20Km/h; andarranging an electronic speed switching button and a speed control knob, wherein the overhauling vehicle can hold 1 to 2 people and can be powered by a storage battery. According to the city underground comprehensive pipe rack overhauling method provided by the invention, the tracks are paved in a comprehensive pipe rack, and the overhauling vehicle is arranged on the tracks, so that the manpowerand the time can be saved, overhauling personnel can arrive at the scene for the first time when finding the problem so as to make urgent repair, and the occurrence of bigger loss can be avoided; andthrough the overhauling method, the overhauling personnel can quickly and accurately arrive at any position of the pipe rack, so that the daily round check time of the inner part of a rack body is greatly shortened, the round check time is greatly saved, and the overhauling personnel can accurately and timely arrive at the fault position when faults occurred.

Description

technical field [0001] The invention relates to a method for overhauling an urban underground comprehensive pipe gallery, and is particularly suitable for a branch line comprehensive pipe gallery with a long length and a small width. Background technique [0002] After the comprehensive pipe gallery project is completed, the comprehensive pipe gallery really begins to enter the use stage, and the use stage also requires people to inspect and inspect. If there is a problem with the comprehensive pipeline in the comprehensive pipe gallery, it will not only affect a certain one Whether the pipeline can be used or not will affect the use of pipelines in an area. At present, large-scale integrated pipeline corridors generally reserve 2m wide engineering roads, while comprehensive pipeline corridors for branch lines still require maintenance personnel and daily maintenance It is not only a waste of manpower and time for personnel to carry out daily inspections and maintenance work...

Problems solved by technology

[0002] After the comprehensive pipe gallery project is completed, the comprehensive pipe gallery really begins to enter the use stage, and the use stage also requires people to inspect and inspect. If there is a problem with the comprehensive pipeline in the comprehensive pipe gallery, it will not only affect a certain one Whether the pipeline can be used or not will affect the use of pipelines in an area. At present, large-scale integrated pipeline corridors generally reserve 2m wide engineering roads, while comprehensive pipeline corridors for branch lines still require maintenance personnel and daily maintenance It is not only a waste of manpower and time for personnel to carry out daily inspections and maintenance work on foot, but also when a problem is found, it is difficult for the maintenance personnel to arrive at the scene for emergency repair at the first time
