Elastic wave assisted cement grouting water stop model test device

Abstract

The invention discloses an elastic wave assisted cement grouting water stop model test device which comprises a test box and an elastic wave emitter arranged in the test box. One side of the test box is communicated with a grouting assembly, and the other side of the test box is communicated with an adjustable pressurizing water injection assembly; and cement grout is input into the test box through the grouting assembly, and the adjustable pressurizing water injection assembly applies pressure to water and inputs the pressure into the test box. The test box is arranged, the interior of the test box is equally divided through the partition plates, the water pressure, elastic wave strength and cement grout in each test area can be freely regulated and controlled, comparison can be conducted in the test, influences on the cement grout under different conditions are fully reflected, the water pressure in the test box can be regulated, water pressure at different depths can be simulated, the influence of different water pressure on cement grouting can be conveniently tested, and cement grout input into the test box can be crushed and refined by arranging the crushing structure.

Description

technical field [0001] The invention relates to the technical field of grouting water stop experiment. Specifically, it is an elastic wave assisted cement grouting waterstop model test device. Background technique [0002] When carrying out engineering construction in water-rich strata, groundwater often affects the safety and smooth progress of engineering construction, and affects the safety of engineering construction. The grouting method is an effective method for anti-seepage, plugging, reinforcement and correction of building deflection in engineering construction. ; The propagation of elastic waves in the rock-soil medium makes the liquid in the pores produce a pressure gradient, which can affect the movement of groundwater and cement slurry; The grouting test equipment cannot apply low-frequency and high-frequency elastic waves, cannot simulate the real groundwater seepage conditions, and cannot meet the test requirements for testing the grout migration law, which c...

[0002] When carrying out engineering construction in water-rich strata, groundwater often affects the safety and smooth progress of engineering construction, and affects the safety of engineering construction. The grouting method is an effective method for anti-seepage, plugging, reinforcement and correction of building deflection in engineering construction. ; The propagation of elastic waves in the rock-soil medium makes the liquid in the pores generate a pressure gradient, which can affect the movement of groundwater and cement slurry; In order to study the water-stop effect of elastic wave-assisted cement grouting technology in real water-rich strata The grouting test equipment cannot apply low-frequency and high-frequency elastic waves, cannot simulate real groundwater seepage conditions, and cannot meet the test requirements for testing the grout migration law, which can no longer meet the requirements
