Embodiment Construction

[0013] Such as Figure 1-Figure 3 The shown aquifer experimental simulation device includes a sand tank 1, a brine tank 2, and a pressure-bearing cover plate 3. The sand tank 1 and the brine tank 2 are an integral structure. Preferably, the sand tank-brine tank is made of plexiglass, The height is 35cm. The pressure-bearing cover plate 3 is as long as the sand tank-brine tank, and a support plate 14 is provided on the edge of the top opening of the sand tank-brine tank. Evenly distributed threaded connectors 141 are provided on the support plate 14 , and corresponding through holes 36 are provided on the edge of the pressure-bearing cover 3 .

[0014] The sand tank 1 is provided with a salt water area 11, a sand filling area 12 and a fresh water area 13 in sequence. Preferably, the width of the sand tank 1 is 5 cm, and the lengths of the salt water area 11, sand filling area 12, and fresh water area 13 are 5 cm, 120 cm, and 5 cm respectively. A plurality of large-diameter op...

Abstract

The invention discloses an aquifer experiment simulating device. The device comprises a saltwater tank, a sand tank and a pressure-bearing cover plate, wherein the saltwater tank is communicated withthe sand tank; the saltwater tank and the sand tank are connected with the pressure-bearing cover plate to form a relatively closed pressure environment to simulate a confined aquifer; and a non-confined aquifer can be simulated when the pressure-bearing cover plate is removed. The device has the beneficial effects that a plurality of water/gas injection holes for water/gas injection are formed inthe side face of a sand filling area in the middle of the sand tank to solve the problem that the effects of various seawater intrusion treating methods cannot be simulated in the prior art; a saltwater area of the sand tank is directly connected with the large-volume saltwater tank to solve the problem that the saltwater concentration is unstable when the aquifer of a coastal zone is simulated in the prior art; in addition, the whole process of saltwater intrusion can be directly observed and recorded by the device to meet the various requirements of physical model experiments for seawater intrusion research; and the device is reasonable in structure, reliable in performance, simple and convenient to operate and strong in comprehensiveness.

Description

technical field [0001] The invention relates to a simulation device for a physical experiment, in particular to a simulation device for an aquifer experiment in a coastal zone. Background technique [0002] With economic development and population growth, the problem of insufficient fresh water supply has become more and more acute. The depletion of surface water resources and increasing pollution have forced people to turn their attention to groundwater to fill the gap of insufficient fresh water supply, especially in many coastal areas. However, seawater intrusion often exists in these coastal areas, leading to a series of ecological and environmental deterioration problems, such as water quality deterioration, soil salinization, and desertification, which have caused serious regional environmental damage in coastal areas. Nowadays, seawater intrusion has become a major environmental geological disaster commonly faced by coastal areas, and has become an important factor r...
