High pressure curtain grouting consolidation simulation experiment method and device

Abstract

The invention provides a high-pressure curtain grouting consolidation simulation experiment method and device, belonging to the technical field of mine curtain grouting. It includes a simulated confining chamber filled with water and capable of simulating real groundwater pressure. A grout experiment chamber simulating real grouting and its pressure is set in the confinement chamber. The grout experiment chamber is connected with a consolidation parameter monitoring device to detect different drainage conditions. Changes in the state of the slurry under certain conditions or under the set conditions are monitored in real time to obtain slurry consolidation parameters. Solve the technical problems existing in the prior art that the determination of technical parameters of grouting technology is inaccurate and the distance from the real grouting environment is too large, and relatively accurate and closer to actual test data can be obtained in the simulation test, and the experiment The time is greatly shortened, which is conducive to scientifically selecting the best grouting process and experimental research on new grouting materials, improving the quality and efficiency of curtain grouting, and has greater economic and social benefits.

Description

technical field [0001] The invention relates to the technical field of mine curtain grouting, in particular to a high-pressure curtain grouting consolidation experiment device. Background technique [0002] At present, there is no device or platform specially used for slurry coagulation and solidification experiments in China. Most of the existing grout coagulation and solidification experiments are carried out under natural conditions, which are far from the real grouting environment, and relatively accurate test data cannot be obtained in the test. Its main disadvantages are: [0003] 1. Various experimental parameters of the slurry cannot be set under various pressure conditions according to the design requirements; [0004] 2. The setting and curing time is very long (the initial setting time generally takes about 7 days); [0005] 3. It is impossible to carry out tests on the grouting process, such as the setting and curing time and strength of the grout under differ...
