Abstract

The invention discloses a simulation testing system of groundwater recharge and an establishment method thereof and belongs to the technical field of environmental protection. The simulation testing system structurally comprises a model frame and a water supply tank, wherein the model frame comprises a test soil tank and test water tanks, the test water tanks are arranged at the two ends of the test soil tank so as to adjust the water level of underground water in the test soil tank, the adjacent faces between the test water tanks and the test soil tank are water-permeable faces, a recharge well is arranged in the test soil tank, an osmotic pressure sensor and a temperature sensor are arranged in a soil layer of the test soil tank and are connected with a control platform, and a water supply tank is communicated with the recharge well through a water supply pipeline. The simulation testing system is simple in structure and lifelike in simulation, can visually show the recharge process of the underground water and facilitates the study on the influence rule of recharge pressure to an underground water seepage field and a spatio-temporal evolution rule of a rainfall curved-surface shape.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a groundwater recharge simulation test system and a construction method thereof. Background technique [0002] With the acceleration of urbanization in China, the scale of urban buildings and the utilization of underground space resources continue to increase, and the area and depth of foundation pits are increasing. The process of foundation pit excavation will inevitably cause the gushing of groundwater. In order to make up for the loss of groundwater, groundwater recharge has become an indispensable method. Scholars in my country have also carried out a lot of model test research work, but there are also obvious weaknesses. The current groundwater recharge model cannot simulate the actual groundwater recharge state well, and the accuracy of the test is poor. Contents of the invention [0003] In view of the above problems, the object of the present inventio...
