A method for installing a comprehensive support and hanger in an underground space

Abstract

The invention discloses a method for installing a comprehensive support hanger in an underground space. The method comprises the following steps of: placing the comprehensive support hanger of a corresponding section and each section of pipeline below each comprehensive support hanger fixing point; assembling the movable automatic lifting platform, temporarily fixing the comprehensive support hanger on the movable automatic lifting platform, and mounting each section of pipeline on the comprehensive support hanger according to design requirements; rectifying the plane position of the comprehensive support hanger by the rectifying device, so that the fixed end of the comprehensive support hanger is aligned with the fixed point of the comprehensive support hanger; and controlling the movableautomatic lifting platform to rise to a preset height, and connecting and fixing the comprehensive support hanger at the comprehensive support hanger fixing point. The method has the advantages thatthe movable automatic lifting platform is adopted for carrying out supporting operation on the comprehensive supporting and hanging frame, the comprehensive supporting and hanging frame can be conveniently constructed in a narrow and compact space, operation is easy, and the safety risk is low; the adjusting and calibrating functions are achieved, and accurate installation of the comprehensive supporting and hanging frame can be achieved.

Description

technical field [0001] The invention relates to the technical field of installing a comprehensive support and hanger of a subway station, in particular to a method for installing a comprehensive support and hanger in an underground space. Background technique [0002] The public corridor in the equipment area of ​​the subway station is the routing channel for dozens of professional pipelines. To fully arrange these pipelines above the corridor often needs to give full play to the utilization value of every inch of space. The public corridor in the equipment area is usually equipped with integrated supports and hangers with a height of more than 2.5 meters, and the lateral distance from the masonry inner wall is only 100-200mm wide. It is extremely difficult to construct integrated supports and hangers in such a small underground space, and the city In rail transit projects, the problem of intersection between mechanical and electrical installation engineering and integrated ...

AI Technical Summary

Problems solved by technology

The public corridor in the equipment area is usually equipped with integrated supports and hangers with a height of more than 2.5 meters, and the lateral distance from the masonry inner wall is only 100-200mm wide. It is extremely difficult to construct integrated supports and hangers in such a small underground space, and the city In rail transit projects, the problem of intersection between mechanical and electrical installation engineering and integrated pipeline installation and construction is relatively serious, and the mutual influence between each process is more prominent, which seriously restricts the progress of on-site construction. At present, construction units in the industry have not yet solved this problem. Generally, they follow the integrated pipeline drawings The comprehensive support and hanger installation is carried out first, and then the ventilation pipe-bridge frame-water pipe installation is carried out. This kind of construction process has the following disadvantages: if the previous process has not been completed, the subsequent work will not be able to advance, and there are certain safety hazards (high operations), quality hazards (quality problems caused by construction inconvenience), and ultimately affect the construction quality, construction progress and construction cost
