Title:
COAL ROCK FRACTURE VISUAL GROUTING DEVICE AND TEST METHOD
Document Type and Number:
WIPO Patent Application WO/2024/012419
Kind Code:
A1
Abstract:
A visual coal rock fracture grouting device and a test method. The test device comprises a visual fracture grouting box body, a box body support, a grouting device and a monitoring device; a bottom plate is divided into four equal-sized areas in which rubber cushion blocks having different specifications are respectively provided and are used for simulating different fissure widths and tortuosity, artificial original rock films are attached to the insides, and a grouting hole (17) and a plurality of pressure measuring holes (16) are formed in the center of an upper top plate; the grouting device is composed of an air compressor (2), a grout storage barrel (1), a pneumatic agitator (6), a grout conveying pipe (9), a grouting pipe (10) and an air guide pipe (5); the grouting hole (17) is connected to a grout control valve (7) at the bottom of the grout storage barrel (1) by means of the grout conveying pipe (9); and the air compressor (2) is separately connected to the grout storage barrel (1) and the pneumatic agitator (6). According to the device, the fissure grouting process under different grouting conditions such as different fracture widths, roughness, grouting resistance and porosity of pore channels can be simulated, grouting under different fracture conditions can be simulated at the same time, and the difference in grout diffusion forms can be clearly and visually analyzed and compared by means of the visual box body.
