Water seepage collecting and testing system for fluid-solid coupling test

Abstract

The invention discloses a water seepage collecting and testing system for a fluid-solid coupling test. The water seepage collecting and testing system comprises a transparent waterproof sealed testing tank, wherein the testing tank internally comprises a water tank area, a material area and a water amount collecting area which are sequentially arranged from top to bottom, the water tank area is communicated with the material area, a water permeable clapboard is arranged between the material area and the water amount collecting area, and the water tank area is connected with a water pressure control device. The water seepage collecting and testing system solves the problems that the water seepage amount is difficult to accurately collect and the seepage rate is difficult to test in a fluid-solid coupling model test, truly simulates the coupling effect of a water body and similar materials, and simultaneously realizes the visualization of the testing system in the model test. When the visualized water seepage collecting and testing system is applied in the model test, compared with the conventional research, the water seepage collecting and testing system can realized the accurate collection of the seepage rate and the water seepage amount in the fluid-solid coupling test, and can enhance the visualization of the fluid-solid coupling test process, so that the test process is authentic and creditable, and test results are close to practical engineering.

Description

technical field [0001] The invention relates to a model test system, in particular to a seepage collection test system for fluid-solid coupling test of visualized underground engineering model test. Background technique [0002] With the development of our country's social economy and the take-off of transportation, the construction of infrastructure and the development and utilization of space are gradually expanding underground. With the continuous increase in the number of underground engineering construction, the scale is increasing, the scope is expanding, and the difficulty of engineering construction is also increasing. For underground engineering, a prominent feature is that buildings are under the coupling effects of multiple media such as rock (soil), groundwater, and gas for a long time. The research on the mechanism of fluid-solid coupling in underground engineering has become a hot spot. It is an effective method to explore the laws of fluid-solid coupling in u...

AI Technical Summary

Problems solved by technology

However, the traditional underground engineering model test technology has obvious weaknesses. The visibility of the model test system is poor, and it is difficult to directly observe the test process in the test project; there are few studies on the fluid-solid coupling test technology under real conditions. It is difficult to study the interaction mechanism between fluid and solid through experiments; there is a lack of accurate test methods for material permeability rate and water seepage, and the key index in the fluid-solid coupling test—permeability test method is backward
