Abstract

The invention discloses a three-dimensional visible testing system of a dynamic water grouting model. The testing system comprises a test bench, a grouting system, a water supply tank and a water receiving tank. The test bench is composed of six side walls connected by modular bolts, a toughened glass box is placed in the test bench and clings to the inner wall of the test bench, and the diffusion state of slurry can be dynamically observed through the toughened glass; the grouting system is composed of an air compressor, a pressure bearing cylinder and a grouting pipe, and stable grouting pressure is provided by air pressure; the water supply tank is used for providing a dynamic water environment for the model test. Meanwhile, the invention also discloses a testing method of the system. The three-dimensional visible testing system and method of the dynamic water grouting model researched in the invention can be used for simulating grouting in a dynamic water environment under a visible condition. Compared with previous research, the system is used for successfully simulating the grouting in the dynamic water environment under the visible condition, thereby obtaining relative conclusions more conforming to engineering practice.

Description

technical field [0001] The invention relates to a three-dimensional visualized dynamic water grouting model test system and a test method thereof. Background technique [0002] Grouting is an effective means of strengthening weak and broken surrounding rock and sealing groundwater in underground engineering. Chinese scholars have carried out a lot of model test research work on grouting theory, but there are still some shortcomings. Grouting model tests are generally in It is carried out in still water or anhydrous environment, which is contradictory to the fact that many grouting projects are carried out in flowing groundwater environment, and most of the grouting model experiments are carried out in a closed environment, and it is impossible to visually observe the grout diffusion . Contents of the invention [0003] The object of the present invention is to provide a three-dimensional visual dynamic water grouting model test system and a test method thereof in order to...
