Problems solved by technology

In recent years, because production units are busy completing their own production tasks, it is difficult to accept college teachers and students for scientific research and on-site teaching practice, and the field pumping test costs a lot, so it is necessary to strengthen scientific research and practical teaching in the laboratory to make up for the Insufficiency of Field Test and Practice

Embodiment Construction

[0054] Referring to FIGS. 1 to 4 , a water pump 2 is installed in the water storage tank 1 . Simulation box 3 is contained on the support that is positioned at the top of water storage tank and bottom plate keeps level all the time. The walls of the simulation box are made of plexiglass. Two permeable mesh plates 4 separate the simulation box into a water supply chamber 5 and a pumping well 6 located upstream and downstream, and a simulation chamber 7 between the water supply chamber 5 and the pumping well 6 . The cross-sectional shape of the simulated cavity 7 is shown in Fig. 3 as a sector with a central angle α = 20°, in which there is an aquifer 8 with a thickness of 40 cm. On the top surface of the aquifer, there is a water-resistant roof 36 parallel to the bottom plate, and a water-resistant layer 37 is arranged on the water-resistant roof. Seven groups of piezometric tubes 9 with scales 33 are vertically mounted on the wall of the simulated cavity at equal distances, ...

Description

Technical field: [0001] The invention relates to a pressure-bearing complete well pumping simulation device for studying groundwater movement laws. Background technique: [0002] When studying groundwater movement, mathematical methods are often used. The premise is to solve the aquifer or aquifer system under a series of generalization and restriction conditions. If these generalizations and restriction conditions can still reflect the main characteristics of the actual aquifer features, then a mathematically analytical solution is available. [0003] But for the actual aquifer, if its heterogeneity, anisotropy and complex boundary geometry do not allow too much generalization, then the mathematical method is difficult to apply, and the mathematical method is relatively abstract, making it difficult for beginners to understand . Therefore, the simulation method is used to study the law of groundwater movement under complex conditions. Among them, physical simulation is a...
