Abstract

The invention discloses a foundation pit excavation model test device based on surface water penetration. The foundation pit excavation model test device comprises a model box, wherein supports are arranged on the side walls of the two sides of the model box; a rotating rod is rotatably connected to the side wall of one support and penetrates through the other support to be fixedly connected witha handle; a test soil body is arranged in the model box; a slope protection net is arranged on the side wall of the test soil body; the side wall of the slope protection net is connected with the sidewall of the upper end of the test soil body through pin shafts; and a water tank is arranged on the side wall of the model box. The invention also discloses a using method of the foundation pit excavation model test device based on the surface water penetration. The using method adjusts the environmental simulation quantity of the model test device according to the environmental change of a foundation pit so as to meet the test requirements. According to the foundation pit excavation model test device based on the surface water penetration and the using method, the influence of variables suchas sun and rainwater on a foundation pit model can be accurately simulated, then the pit excavation under the condition that the various natural variables exist is measured, and the measurement accuracy of the model box is improved.

Description

technical field [0001] The invention relates to the technical field, in particular to a foundation pit excavation model test device based on surface water infiltration and a use method. Background technique [0002] In recent years, with the rapid development of urban construction, the number of deep foundation pit projects is increasing day by day. The foundation pit projects are facing new trends of deep depth, large scale and complex surrounding environment. In particular, deep foundation pit projects in coastal and riverside areas are faced with challenges such as abundant groundwater, complex construction environment and difficult construction. In order to solve the impact of groundwater on the excavation of the foundation pit, various dewatering facilities are often used in the construction of the foundation pit to carry out intensive precipitation of the groundwater in the foundation pit to ensure that the foundation pit can be excavated in an anhydrous state. When t...
