Abstract

The invention discloses a test simulation device for a confined aquifer. The test simulation device comprises a sandy soil container, a feed water height control device, a water supply device and a pressure measuring and observing device, wherein the sandy soil container is arranged obliquely, one end of the sandy soil container is provided with a first water inlet pipe, a plurality of pressure measuring nozzles are uniformly distributed on the front side wall, the rear side wall and the bottom face of the sandy soil container and are connected with one pressure measuring pipe of the pressure measuring and observing device through a connecting pipe, a water pumping pipe is arranged at the bottom of the sandy soil container, a discharge casing is fixed outside a side wall at the lower end of the sandy soil container, the top of the sandy soil container is connected with a pressure-bearing top cover which is provided with at least one overflow pipe; the feed water height control device comprises a water tank, which is connected with a lift device; and the pressure measuring and observing device comprises a pressure measuring plate and a plurality of pressure measuring pipes which are arranged on the pressure measuring plate side by side. By means of the scheme, the test simulation device disclosed by the invention can simulate the change characteristics of a three-dimensional flow field of the confined aquifer under a natural condition and a mining condition, and test simulation device is simple in structure and low in price.

Description

technical field [0001] The invention relates to a test device, in particular to a pressure-bearing aquifer test simulation device. Background technique [0002] In groundwater science and research, the understanding and research of confined aquifers are generally carried out through field experiments. However, field experiments are generally expensive, poorly intuitive, and it is difficult to study the groundwater flow of confined aquifers under different external conditions. Therefore, the development of a confined aquifer test device to simulate the movement characteristics of groundwater under different recharge, runoff and discharge conditions is of great importance for the study of the movement law of groundwater flow in porous media under confined conditions. Practical significance. Contents of the invention [0003] The object of the present invention is to provide a test simulation device for a confined aquifer, which has simple structure, low price and more intui...
