Problems solved by technology

[0003] Since the impact of groundwater on the test piece is long-term and continuous, if the test piece is soaked in a static acidic solution, the penetration effect will be poor, and artificial spraying is labor-intensive and uneven, and there is also a threat to the health of the experimenter, so It is necessary to provide a green, easy-to-operate simulation device for acidic solution penetration

Abstract

The invention provides an apparatus for simulating circulatory permeation of an acidic solution to simulate erosive permeation of underground water acidic environment upon a test piece; the apparatus comprises: a solution receiving portion that is a rectangular closed container; a test piece receiving portion arranged in the closed container to receive a test piece and comprising a partition, a perforated tray, and a rotary fixing table sequentially from top to bottom, wherein the rotary fixing table is a four-jaw self-rotating fixing table; a solution circulation portion arranged in the closed container and having a solution pump and four universal plastic pipes arranged above the solution pump, wherein the universal plastic pipes are arranged in central symmetry; and a PH monitor portion mounted on the inner wall of the closed container to monitor PH value of the acidic solution. The apparatus of the invention enables a test piece to be permeated by an acidic solution comprehensively and continuously, is simple to operate, and is free of labor consumption, green and pollution-free.

Description

Technical field [0001] The invention relates to a simulation device, in particular to a simulation device for circulating and permeating an acid solution. Background technique [0002] As an active factor affecting the mechanical properties of rock masses, the research on the effects of groundwater on rock strength and elastic modulus has attracted more and more attention. Groundwater is an important geological force. It interacts with the rock mass and changes the physical, chemical composition and mechanical properties of the rock mass. Among them, the influence of the acidic environment of groundwater on the mechanical properties of rocks is particularly valued, so simulating the acidic environment of groundwater is very important for scientific research. [0003] Since the impact of groundwater on the specimen is long-term and continuous, if the specimen is immersed in a static acid solution, the penetration effect is poor, and manual spraying is labor intensive and uneven, wh...
