Experiment device capable of uniformly distributing water and simulating water-rock interaction

Abstract

The invention discloses an experiment device capable of uniformly distributing water and simulating water-rock interaction. Leaching liquid in a liquid supply bottle is leached to a spiral water distributor in a soil column body through a water inlet pipe and is transmitted to other annular water grooves through communicating a flow guide groove of the annular water groove with the smallest radius; the leaching liquid is uniformly leached into soil filled into the soil column body through small holes formed in the annular water grooves; a leaching water sample passing through the soil column body is transmitted into a spiral water distributor in a rock core column body through a filtrate sharp guide pipe and is leached into rocks filled into the rock core column body; an atmospheric precipitation vertical flow direction uniform infiltration and leaching process is simulated; the flow direction of a bedding rock layer is also realized in the simulation process and a flowing condition ofunderground water also can be accurately simulated; the simulation device is simple in structure; the volumes of the soil column body and the rock core column body are relatively small and a few of materials are needed; the cost of the simulation process is extremely reduced.

Description

technical field [0001] The invention belongs to the technical field of groundwater research, and in particular relates to an experimental device capable of both uniform leaching and simulating the interaction between groundwater and rock formations. Background technique [0002] As one of the important components of the earth's water body, groundwater has become an important water source for agricultural irrigation, industrial and mining enterprises, and urban domestic water due to its stable water supply conditions and good water quality. It is an essential and important water resource for human society. However, in recent years, due to the influence of human activities, the situation of groundwater pollution has become increasingly serious. In order to control and control the problem of groundwater pollution, it is very important to understand and study the evolution process and evolution results of groundwater in the process of flow. The evolution process in the groundwa...

Problems solved by technology

[0003] The inventor found that when the soil column simulation device used in the related art to simulate the interaction between groundwater and rock is too large, too much material needs to be consumed, which makes it difficult to carry out the simulation experiment. The medium stability
