Abstract

The embodiment of the invention provides a mounting method of a prefabricated pipe gallery. The mounting method comprises the steps: after a current prefabricated pipe gallery single body is horizontally hoisted into a predetermined rail through a hoisting system to enable the current prefabricated pipe gallery single body to be located between a jack and a roadheader, the current prefabricated pipe gallery single body is jacked in the heading direction through the jack; the heading direction is controlled through the roadheader, a soil body in the heading direction is excavated in a top openmode and meanwhile jacked into the current prefabricated pipe gallery single body through the jack, and the position, between the roadheader and a working well, of the outer side of the pipe gallery is filled with liquid to reduce frictional resistance; a single body of the next section and the current prefabricated pipe gallery single body are connected in the jacking direction of the jack, and thus the single body of the next section serves as the current prefabricated pipe gallery single body again; and the steps are repeated till all the prefabricated pipe gallery single bodies are mounted. According to the mounting method of the prefabricated pipe gallery, the construction cost is low, noise is small, pollution is small, the destroyed soil body face is narrow, rainfall and support work is reduced, the construction speed is high, and quick backfill can be achieved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of underground engineering construction, in particular to a method for installing a prefabricated pipe gallery. Background technique [0002] At present, the construction method of prefabricated pipe gallery mainly adopts the comprehensive pipe gallery construction of shield method, pipe jacking construction and open-cut prefabricated assembly technology. method. [0003] The current method has disadvantages such as large impact on the surrounding environment, large amount of earth excavation, long construction period, consumption of a large amount of turnover materials or temporary materials, and high labor costs. Contents of the invention [0004] An embodiment of the present invention provides a method for installing a prefabricated pipe gallery, which is used to solve the problems of long installation period and large excavation of the prefabricated pipe gallery in the prior ...
