Abstract

The invention discloses a visual splitting grouting diffusion process simulation test device and a using method. The device comprises a model box, a grouting device, an image real-time collection system and a ground stress loading system; the model box is composed of a transparent shell; a transparent material simulating a grouting environment is arranged in the transparent shell; a grouting hole is formed in the transparent shell so as to accommodate slurry injected by the grouting device; the ground stress loading system is composed of air injecting equipment and a flexible airbag; the flexible airbag wraps the model box; the air injecting equipment applies stress to the model box through the flexible airbag; and the flexible airbag is transparent so as to enable the image real-time collection system to collect variations of the model box and the flexible airbag, realize visual simulation of the splitting grouting slurry diffusion process and track the splitting grouting diffusion process. With adoption of the visual splitting grouting diffusion process simulation test device and the using method, visual simulation of the splitting grouting slurry diffusion process is realized, so that the splitting grouting diffusion process of slurry in a soil body is visual.

Description

technical field [0001] The invention relates to a visual splitting grouting diffusion process simulation test device and a use method. Background technique [0002] Split grouting is a widely used foundation reinforcement method. Under a certain grouting pressure, the grout splits inside the soil to form grouting cracks. As the grouting pressure continues to increase and the grout is gradually injected, The slurry in the soil will form a criss-cross network of slurry veins near the borehole. [0003] Studies have shown that the effect of soil reinforcement is not only directly related to the grouting pressure, but also has a great relationship with the width of the cracks split by the grout in the soil and the distance of crack diffusion. However, because the soil material itself is opaque, whether it is In the engineering site or in the model test, the dynamic diffusion process of the slurry cannot be obtained due to the invisibility of the injected medium.
