Simulation test device for directional drilling grouting slurry diffusion

Abstract

The invention provides a simulation test device for directional drilling grouting slurry diffusion, relates to the technical field of grouting simulation experiments, and aims at solving the problems that when an existing simulation test device for grouting slurry diffusion is used, a protection structure cannot be conveniently and fixedly installed, and protection cannot be carried out when a rock cannot bear pressure and is broken. The device comprises a main body, a clamping block, a guide piece and a protection piece, wherein the main body is of a rectangular structure, moving wheels are arranged at the bottom of the main body, the guide piece is mounted at the front end of the main body, the clamping block is used for being fixed in the main body, after a to-be-tested rock mass is placed above the main body, the protection piece can be mounted, the top end of the clamping block can be embedded into a clamping groove, the rock mass can be surrounded by the protection piece, the rock mass cannot burst out to injure people when the rock mass cannot bear pressure fragmentation in a test so as to test the pressure bearing capacity of the to-be-tested rock mass, and if the rock mass is not broken, the protection piece can be directly taken down to observe the diffusion degree.

Description

technical field [0001] The invention belongs to the technical field of grouting simulation experiments, and more specifically relates to a simulation test device for directional drilling grouting slurry diffusion. Background technique [0002] Grouting to transform aquifers is an effective method to solve the threat of water inrush above confined water. Directional drilling grouting uses coal seam drilling progressive extension technology and drilling trajectory control technology to improve the coal seam drilling rate and realize deep hole precision drilling. , to conduct advanced detection and grouting treatment of hidden water-conducting subsidence columns, faults and fissures in the aquifer area, and before directional drilling and grouting, simulation experiments on grout diffusion are usually required. [0003] For example, the application number: CN201910331147.1 involves a simulation test method for directional drilling grouting grout diffusion, including a grouting ...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a simulation test device for directional drilling grouting grout diffusion, to solve the problem that the existing simulation test device for grouting grout diffusion cannot conveniently fix and install the protective structure when it is in use. When the rock block cannot bear the pressure and breaks, it is protected, and when the existing simulation experiment device for grouting slurry diffusion is in use, it is impossible to open holes for grouting at the appropriate position under the premise of installing the protective structure, and it is impossible to It is necessary to drill holes in appropriate positions without affecting the protective structure
