Abstract
The utility model discloses a confined-unconfined aquifer experiment simulation device. The main body of the device is a simulation tank which is loaded with sandy soil. Two sides of the simulation tank are respectively connected with an adjustable overflow tank which can control a boundary water level of the simulation tank. The edge of the upper part of the tank body is an organic glass support plate which forms a relatively sealing confined environment along with an overlaying rubber gasket and an organic glass cover plate, and the confined environment is used for the simulation of the changes of an underground water level of the confined aquifer. When the cover plate is removed, the changes of an underground water level of the unconfined aquifer can be simulated. The front and back surfaces of the simulation tank are respectively provided with a plurality of piezometric tube nozzles which are respectively connected with piezometric tubes on a right piezometric plate through rubber hoses, thereby forming an integrated observation system. The simulation device can simulate the changes of the boundary water level, the changes of the underground water level of the unconfined aquifer, and the underground water level of the confined aquifer. By utilizing a drainage hole at the lower part of the simulation tank, the dynamic changes of the water levels of the unconfined and unconfined aquifers under the condition of drainage can be simulated. The simulation device is advantageous by achieving the confined-unconfined aquifer simulation experiment by utilizing the same device.
