An Indoor Foundation Pit Dewatering Test Method

Abstract

The invention provides an indoor foundation pit precipitation test method, which comprises the following steps: S1, at least one formation material is selected; S2, physical and mechanical test exploration on the formation material is carried out; S3, a simulation foundation pit test box is designed; S4, simulation of foundation pit precipitation is designed; and S5, data monitoring is carried outon the foundation pit precipitation test. According to the indoor foundation pit precipitation test method provided in the invention, the problems of lacking study such as a water level change mechanism outside the pit, surface settlement outside the pit and underground continuous wall deformation caused by precipitation of an incomplete well in the pit when the aquifer is thick and the foundation pit continuous wall does not completely isolate aquifers inside and outside the foundation pit in the prior art can be solved, the method can provide a basis of subsequent relevant researchers, andfoundation pit precipitation test study for a uniform or layered foundation and different foundation pit forms.

Description

technical field [0001] The invention relates to the field of foundation pit penetration. More specifically, it relates to an indoor foundation pit precipitation test method. Background technique [0002] When the foundation pit is located in a deep aquifer, considering the difficulty of construction and economic factors, the retaining wall of the foundation pit fails to isolate the groundwater inside and outside the pit. It is very important to study the mechanism of water level change on the surface settlement outside the foundation pit and the deformation of the retaining wall of the foundation pit, which is of great significance and practical value to the foundation pit engineering. [0003] However, in the existing technology, there is little specific impact on the groundwater inside and outside the pit when the retaining wall of the foundation pit does not cut off the groundwater inside and outside the pit. The phenomenon of groundwater seepage at the bottom of the wa...

Problems solved by technology

[0005] The invention provides an indoor foundation pit dewatering test method to solve the problem of water level changes outside the pit caused by dewatering of incomplete wells in the foundation pit when the aquifer is relatively thick and the diaphragm wall of the foundation pit does not completely isolate the aquifer inside and outside the foundation pit. The mechanism, surface settlement outside the pit, and the deformation of the underground diaphragm wall have been systematically studied, so that subsequent relevant researchers can use this method as a basis to conduct uniform or layered strata and different foundation pit forms.
