[0002] Geotechnical engineering includes subway, tunnel, slope, well and gallery, culvert, dam, etc. When encountering geological fracture zone, partial soft rock, easy falling piece, landslide instability, large deformation, water or water inrush danger, pipe gushing, etc., grouting reinforcement is one of the commonly used methods. Engineering grouting is a method of injecting certain curable slurry into the cracks or pores of the rock foundation by appropriate methods, replacing, filling, extruding, etc. to improve its physical and mechanical properties. Building engineering grouting technology can be divided into two categories: static pressure grouting and high pressure jet grouting. When grouting treatment is carried out on geotechnical engineering, a geotechnical engineering grouting device is needed.
