Abstract

The invention discloses a seawater intrusion simulation test sandbox, which belongs to the technical field of test simulation devices. A medium chamber for containing water-containing media such as sandstone and soil is arranged in the middle of the test sandbox. The left and right ends of the test sandbox are respectively equipped with The seawater chamber for dyed seawater and the freshwater chamber filled with deionized water; the main body of the test sand box is made of acrylic board; the two sections in the middle of the medium chamber are provided with rubber layers that can be seamlessly overlapped with each other and can be inserted into the box; Both the seawater chamber and the freshwater chamber are divided into ABC three chambers; the seawater chamber C is separated from the medium chamber in the middle of the test sand box by a porous plate and nylon mesh; the upper and lower ends of the seawater chamber and the freshwater chamber are equipped with water tanks and recovery boxes. The seawater intrusion simulation test sand box provided by the present invention can realize the control of the water level conveniently and flexibly; it can also change the simulation length conveniently and flexibly, not only can measure the concentration and pressure at a given point, but also can control the water level more freely. Determine the point to measure.

Description

technical field [0001] The invention belongs to the technical field of test simulation devices, and in particular relates to a seawater intrusion simulation test sand box. Background technique [0002] Seawater intrusion is an important problem facing the industrial and agricultural development of coastal cities. Due to unreasonable groundwater exploitation activities, the groundwater system in the local coastal aquifer is unbalanced, and environmental geological problems such as land subsidence, seawater intrusion, and groundwater pollution in the coastal zone occur. The key to the prevention and research of seawater intrusion is to understand the mechanism of seawater intrusion, so as to grasp the current situation of seawater intrusion and accurately predict the development trend of seawater intrusion. The research on seawater intrusion mainly adopts two methods of numerical simulation and physical simulation. [0003] At present, the sandbox simulation method is an impo...
