Embodiment 1

[0033] As shown in the figure, the device includes a water tank 5, a sand box 2 and a water supply device 1, wherein: the water tank 5 includes a pressure-bearing layer partition 6; Composition; water tank 5, front panel 4, rear panel 8 and bottom plate 7 are four major parts of the model, which can be assembled and disassembled, and fastened by bolts. Support; the pressure-bearing layer partition 6 is surrounded by water-stop rubber, which is in close contact with the installation seam of the pressure-bearing layer partition; the water supply device 1 includes a Martens bottle, a faucet and a rubber hose.

[0034] The plexiglass thickness of the water tank 5, the front panel 4, the rear panel 8 and the bottom plate 7 is 10-20 mm. After the model is assembled, the internal height is 500-1000 mm, the internal length is 800-2000 mm, and the internal width is 80-200 mm. , to reduce the influence of boundary conditions brought about by the limited space of the model, and control t...

Abstract

The invention relates to a flat two-dimensional underground water power and quality model apparatus. The apparatus comprises a water tank, a sand tank and a water supply device. The water tank comprises a bearing layer separator plate, can flexible regulate the water power gradient in a model, and simulates the conditions of different bearing layers; and the sand tank comprises supporting bars, a front panel, a rear panel and a bottom panel, and can be used to observe the change of the water power conditions in the model in real time and take a water sample. The apparatus can be used to well control the physical characteristics of an experiment medium, stimulates the migration condition of pollutants in underground water under various conditions in a complex flow state, provides an efficient observation approach, flexible adjusts the functions of the model by assembling and dismounting the model, provides external connection upgrading equipment for the model, improves the model utilization rate and reduces the cost.

Description

technical field [0001] The invention relates to a groundwater hydrodynamic simulation and pollutant migration test simulation device, in particular to a pollutant migration test in an aquifer medium under complex hydrogeological conditions. technical background [0002] In recent years, with the rapid development of the economy, the groundwater body has been polluted to a certain extent, and the water resource environment has also been seriously threatened. The law of groundwater movement is extremely complex, and often has a series of characteristics such as large-scale space and long time. In laboratory experiments, it is often difficult to control the hydrological conditions, boundary conditions, recharge conditions and formation lithology in the model study area. In particular, when the study area is in the coastal area, the aquifer is strongly influenced by the ocean. On the one hand, the groundwater in the coastal area is subject to the interaction of submarine ground...
