Construction method of a large prefabricated pipe gallery

Abstract

A construction method for a large-scale prefabricated pipe gallery. The method is to lay a track in a foundation pit, and transport the large-scale prefabricated pipe gallery to an installation position through translation, so as to realize the installation of the large-scale prefabricated pipe gallery. The present invention adopts the method of laying tracks in the foundation pit and moving the large-scale pipe gallery in the foundation pit. The elevation of the pipe gallery is easy to adjust, the installation accuracy is high, the space of the foundation pit is saved, and the translation method is simple and quick. The hoisting position of the large-scale prefabricated pipe gallery by the jacking trolley of the present invention is jacked up from the bottom with a support rod, and the installation elevation of the pipe gallery is adjusted by threads, which has very high precision and is convenient for construction. When the pipe gallery is connected by prestress, the stability of the erected structure is very high, and the installation error is small. The jacking driving device of the present invention adopts the form of combining the telescopic jacking hydraulic jack and the hydraulic clamping device. Through repeated pushing and pulling, the jacking trolley is pushed to realize the translation of the large-scale prefabricated pipe gallery. The whole device occupies a small space and is convenient for construction. Fast and efficient.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a construction method for a large-scale prefabricated pipe gallery. Background technique [0002] Open-cut prefabricated pipe gallery is an advanced technology emerging in recent years, which can greatly speed up the construction progress and reduce construction investment. The comprehensive pipe gallery project in a certain city is a key project in a province. This project is spread throughout the urban area and is the first batch of pipe gallery demonstration projects in Northeast China. In order to speed up the construction progress of the pipe gallery, the street section of the botanical garden of the city's comprehensive pipe gallery adopts prefabricated pipe gallery, which is designed, manufactured and installed by a group construction product engineering company. [0003] The construction site of the prefabricated pipe gallery straddles a main road in the urban area, ...
