Protection method of pipe penetrating foundation pit
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.
本发明提供了一种穿越基坑的管路的保护方法，该穿越基坑的管路的保护方法包括：1)在管路两侧进行钻孔灌注桩施工；2)开挖管路上方的表层土，进行冠梁和上部支撑梁施工；3)开挖管路的上部土方；4)将管路的下部土方划分为多个待挖段，对多个待挖段按预定开挖顺序分段开挖，在每个待挖段完成开挖之后进行底板和下部支撑梁施工；5)完成管路的下部土方开挖之后，将上部支撑梁与下部支撑梁进行连接；6)基坑开挖。通过本申请提供的技术方案，能够解决现有技术中的无法满足基坑开挖的安全要求的问题。
