Hydraulic Anchor Drill Rig class of its rotary power and propulsion and auxiliary actions are based on hydraulic-driven, driven by a hydraulic motor or internal combustion engines. The wide adjustment range of such rigs for deep pore size and large; the openings and better ability of anti-sticking, convenient operation, is the type most of the domestic manufacturers to adopt. [Tianjin-strong high-pressure pump Co., Ltd. to recommend the star product] triple tube rotary jet grouting material and grouting materials in cement formulation requirements as the main material, and adding different additives, may have a quick-setting early strength, antifreeze, etc. performance. The type of cement slurry more, with the geological conditions and different uses small soft foundation treatment rig, slurry material vary. Ordinary type, general engineering applicable to no special requirements. The general strength grade Portland cement 32.5 above soft foundation treatment rig, no additives, water-cement ratio of 0.8 to 1.5, often 1.0. 28-day compressive strength of consolidation up 1 ~ 2Mpa.
