Problems solved by technology

At present, there is no grouting device specially used for indoor grouting simulation tests in China. The grouting model tests mostly use engineering grouting pumps. The large flow and high pressure cannot monitor and adjust the grouting parameters in real time, which is different from the grouting required by the model test. System mismatch severely restricts the development of grouting model tests, which in turn affects the research on grouting theory

Embodiment Construction

[0036] The present invention will be further described below in conjunction with the drawings and embodiments.

[0037] Such as figure 1 , figure 2 As shown, the overall frame 1-1 is made of phenolic resin material, with a size of 910*640*550mm, and internally processed 6 cylindrical cavities with a diameter of 200*550mm. The cavity structures are divided into 3 groups, which are the first cavity. Body group, second cavity group and third cavity group. The first cavity group is composed of cement-based material slurry storage cavity 2-1 and cement-based material slurry preparation cavity 2-2, and the second cavity group is made of chemical materials The slurry storage cavity 3-1 and the chemical material slurry preparation cavity 3-2 are constituted, and the third cavity group is constituted by the water storage cavity 4-1 and the water preparation cavity 4-2.

[0038] Such as figure 1 , figure 2 , image 3 As shown, the cement-based material slurry storage cavity 2-1 is connecte...

Abstract

The invention discloses a constant-pressure grouting-water supply pneumatic combined servo control system for a test. The system comprises a constant-pressure double-liquid grouting pneumatic servo control system, a constant-pressure water supply pneumatic servo control system and a support. The constant-pressure double-liquid grouting pneumatic servo control system comprises a grout storage cavity, a grout preparation cavity and a pneumatic servo control unit. The constant-pressure water supply pneumatic servo control system comprises a water storage cavity, a water preparation cavity and a pneumatic servo control unit. The grout storage cavity, the grout preparation cavity, the water storage cavity and the water preparation cavity are formed in a whole structure and the whole structure is installed on the support. The grout and liquid matching ratio, grouting pressure and pore water pressure can be adjusted in the test according to test requirements, and a constant-pressure water supply pneumatic servo control device is used in cooperation, so that the combined servo control system is operated stably and efficiently, and the scientificity and the preciseness of the indoor grouting test are guaranteed.

Description

Technical field [0001] The invention relates to a constant pressure grouting-water supply pneumatic combined servo control system for testing. Background technique [0002] In the construction of underground projects such as mines and tunnels, problems such as large wall rock deformation and large water influx often occur, and even water and mud inrush disasters occur, causing huge personal and property losses. Grouting as an effective means to reinforce weak surrounding rocks and treat water damage has been more and more widely used in underground engineering disaster management. Model test is an important method to study the law of grout diffusion and reinforcement mechanism during grouting treatment. The grouting device is responsible for conveying the slurry and the pressure injection of the slurry in the model test, and is an important part of the grouting model test. Model test Due to the small size of the model frame, the complicated changes of the grouting process and t...
