Roadbed underground grouting reinforcement device for road construction

Abstract

The invention discloses a roadbed underground grouting reinforcement device for road construction. The roadbed underground grouting reinforcement device comprises a workbench and an adjusting groove, wherein a feeding hopper is fixed on one side of the workbench; one side of a stirrer is connected with stirring blades; grouting grooves are formed in a grouting rod and a drill bit; and the adjusting groove close to a first hydraulic rod is formed in one side of the workbench. The roadbed underground grouting reinforcement device for road construction is provided with a sliding block and a rotating block, when the drilling angle needs to be adjusted, a third motor is started, the third motor drives a second rotating shaft to rotate, the second rotating shaft rotates to drive the first hydraulic rod to rotate, the first hydraulic rod rotates to drive the grouting rod to rotate in the adjusting groove, so that the orientation of the drill bit at one end of the grouting rod is changed, then a second motor is started, the second motor drives a threaded rod to rotate, the threaded rod rotates to drive the sliding block to move along a guide rod, the sliding block moves to enable the drill bit to gradually get close to the position needing to be drilled for positioning, and the orientation of the drill bit can be conveniently adjusted.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to an underground grouting reinforcement equipment for road construction. Background technique [0002] Grouting (also known as grouting) technology, as one of the most commonly used anti-leakage construction technologies in road construction, has been widely used in the construction of road projects. The grouting method is to inject some curable grout into the cracks or pores of the road foundation to improve its physical and mechanical properties. The purpose of grouting is to prevent seepage, stop leakage, reinforce and correct the deflection of buildings. Grouting Mechanisms include filling grouting, infiltration grouting, compaction grouting and splitting grouting. The grouting materials include granular grouting materials and chemical grouting materials. Granular grouting materials are mainly grouting materials (also called grouting materials), chemical grouting mate...

AI Technical Summary

Problems solved by technology

[0004] Most of the current underground grouting reinforcement equipment is not convenient to use, it is not convenient to maintain the freshness of the grouting material before grouting, it is not convenient to adjust the drilling angle, it is not convenient to disassemble and repair the pipeline, it is not convenient to clean the inside of the grouting rod, and it is easy to residue The grouting material is lowered and solidified to affect the next use. It is not convenient to prevent the soil from entering the grouting rod from the grouting groove during drilling, causing blockage and affecting grouting. Therefore, the current underground grouting reinforcement equipment should be improved.

[0005] In addition, in the prior art, in order to pursue environmental protection, the epoxy resin is often only diluted with a low-molecular glycidyl ether diluent. In this case, the dilution effect is not good, which will make it difficult to maintain the initial low viscosity of the epoxy resin. , far less than the furfural acetone dilution system

Moreover, the mechanical strength of the consolidated body formed after the construction of the existing epoxy grouting materials is sufficient, but the toughness is relatively unsatisfactory
