Abstract

The invention provides a protection method of a pipe penetrating a foundation pit. The protection method of the pipe penetrating the foundation pit comprises the steps of 1, conducting cast-in-situ bored pile construction at the two sides of the pipe; 2, excavating topsoil above the pipe, and constructing a crown beam and an upper support beam; 3, excavating earth above portion of the pipe; 4, dividing earth below the pipe into multiple to-be-excavated segments, conducting segmented excavation on the multiple to-be-excavated segments according to the predetermined excavation sequence, and after excavation of each to-be-excavated segment is completed, constructing a base plate and a lower support beam; 5, after excavation of the earth below the pipe is completed, connecting the upper support beam with the lower support beam; and 6, excavating the foundation pit. By means of the protection method, the problem that in the prior art, the safety requirement of foundation pit excavation cannot be met is solved.

Description

technical field [0001] The invention relates to the technical field of foundation pit construction, in particular to a method for protecting pipelines passing through foundation pits. Background technique [0002] At present, in the process of foundation pit construction, there is a phenomenon that the pipeline passes through the construction position of the foundation pit. During foundation pit excavation, as the earthwork around the pipeline decreases, the pipeline may subside or collapse, posing potential safety hazards. [0003] In the prior art, there is no effective measure against possible settlement or collapse of pipelines. Therefore, there is a problem in the prior art that the safety requirements for foundation pit excavation cannot be met. Contents of the invention [0004] The invention provides a protection method for a pipeline passing through a foundation pit to solve the problem in the prior art that the safety requirements for excavation of the foundati...
