[0003] There are many pipelines in the upper part of the deep foundation pit construction in the city. In the process of pipeline relocation, it is often encountered that there is no relocation route, time, and cost are too high for relocation and reconstruction. It is necessary to relocate the upper part of the deep foundation pit. In-situ protection of pipelines, the conventional construction method usually adopts simple upper suspension and lower support, although it plays a certain protective role, but the inventor found that there are displacements of pipelines, settlement and deformation of pipe gallery during the construction process Happening

The invention relates to an underground pipe gallery in-situ protection method. The method comprises the following steps that a plurality of lifting piles are driven into the two sides of a pipe gallery in the length direction of the pipe gallery; supporting beams are erected on the ground on the two sides of the pipe gallery in the length direction of the pipe gallery, a jacking pieces is installed on the supporting beams, and the jacking pieces are connected with the lifting piles; one side of the pipe gallery is excavated, a construction pit is formed, a guide cylinder is constructed in the construction pit, one end of the guide cylinder penetrates through the lifting pile on one side, and the other end of the guide cylinder extends out of a soil body; a supporting rod is placed in the guide cylinder and moves along the guide cylinder until the supporting rod penetrates through the lifting pile on the other side; the jacking piece drives the lifting piles to be lifted until the supporting rod makes contact with the underground pipe gallery, and the underground pipe gallery is supported; and a displacement monitoring piece is installed in the underground pipe gallery. According to the method, the construction is simple, and the safety of the pipeline is effectively guaranteed.
Description
technical field [0001] The invention relates to the technical field of underground engineering, in particular to an in-situ protection method for an underground utility gallery. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art.
