Multi-stage supporting foundation pit monitoring method

Abstract

The invention relates to a multistage supporting foundation pit monitoring method, and relates to the technical field of foundation pit construction, and the method comprises the following steps: installing water level pipelines: vertically inserting the water level pipelines on the outer side of a foundation pit, arranging a plurality of water level pipelines along the circumferential direction of the foundation pit, and enabling the tops of the water level pipelines to be of a closed structure; the multiple overflow pipelines correspond to the water level pipelines one to one, the overflow pipelines are vertically arranged on one sides of the water level pipelines, and the bottoms of the overflow pipelines are of closed structures; the first communication pipeline is arranged between the water level pipeline and the overflow pipeline, the first communication pipeline is communicated with the interior of the water level pipeline and the interior of the overflow pipeline, and a one-way valve is installed on the first communication pipeline; the inflation assembly is installed on the top face of the water level pipeline, and the inflation assembly is used for inflating the interior of the water level pipeline. The underground water treatment effect can be improved.

Description

technical field [0001] The present application relates to the technical field of foundation pit construction, and in particular, to a multi-level support foundation pit monitoring method. Background technique [0002] Foundation pit monitoring is an important part of foundation pit construction, which refers to various observations on the changes in the foundation pit rock and soil properties, supporting structure displacement and surrounding environmental conditions during the process of foundation pit excavation and underground engineering construction. According to the prediction, the degree of impact of the construction on the surrounding environment will be determined to guide the design and construction, and the so-called information construction will be realized. [0003] In the process of foundation pit monitoring, it is necessary to conduct real-time detection of the groundwater level to ensure that the foundation pit construction can proceed normally. When the grou...

Problems solved by technology

[0004] In the monitoring process of the above-mentioned foundation pit, it is necessary to set up separate equipment to detect the groundwater level. At the same time, when adjusting the groundwater level, it is necessary to use a water pump to extract the groundwater. This method of forced extraction by external force may destroy the distribution structure of the groundwater, and then Cause surface subsidence, and when the groundwater level is detected at the same time, deviations may occur, resulting in the failure of the water pump to pump the water normally, which will cause groundwater to interfere with the construction of the foundation pit
