Surrounding rock reinforcement machine

Abstract

The invention discloses a wall rock reinforcing all-in-one machine. The wall rock reinforcing all-in-one machine comprises a dry powder stirring part, a pulping part and a grouting part, wherein the dry powder stirring part is located at the upper part of the grouting part, and used for stirring the dry powder, and conveying the stirred dry powder to the grouting part; the grouting part is located at the upper part of the grouting part, and used for adding water to the dry powder and pulping, and delivering the prepared sizing fluid to the grouting part; the grouting part is used for pressurizing, pumping and discharging the sizing fluid. The wall rock reinforcing all-in-one machine is simple in operation, rapid in pulping, easy to clean, and flexible in movement; the grouting pressure is easy to control, the pumping flow is uniform and stable; the wall rock reinforcing all-in-one machine can avoid oversize constant impulse pressure.

Description

technical field [0001] The invention relates to the field of construction engineering machinery, in particular to the technical field of rock mass grouting engineering machinery and equipment. Background technique [0002] Rock mass grouting is a grouting project to improve the physical and mechanical properties of rocks with developed joints and fractures or broken zones. Its main purpose is to improve the ability of the rock mass to resist deformation and make the deformation of the rock foundation consistent, and at the same time increase the bearing capacity of the rock mass to ensure the safety of the building. For the bedrock, it is also necessary to meet the anti-seepage requirements, because water seepage may cause erosion damage, generate buoyancy force, deteriorate the properties of the bedrock and reduce its strength, affecting the anti-sliding stability of the entire rock mass. When the rock mass is more permeable, cement grouting is used; when the rock mass is ...

AI Technical Summary

Problems solved by technology

The grouting of the rock mass medium is different. The rock mass medium is tightly closed and has poor permeability. There is often pressurized water in the cracks. If the pressurized water in the cracks cannot be discharged smoothly, it will be difficult for the grout to enter the rock mass; Even if a certain strength is established, its strength is still very different from that of the surrounding rock mass. A slight change in stress and displacement will easily tear and destroy the grouting body, resulting in grouting failure.

[0004] Due to the particularity of rock mass grouting and the characteristics of early strength and fast hardening of grouting materials, grouting equipment is required to be easy to operate, fast grouting, easy to clean, flexible to move, easy to control grouting pressure, uniform and stable pumping flow, and avoid excessive The instantaneous pulsating pressure will not cause the cement slurry to bleed during the pumping process, but it is difficult for the grouting equipment in the prior art to meet the above requirements at the same time
