What is Jet construction method? Churning after construction method is to use the grouting rig drilling pipe with a special nozzle to a predetermined position strata, with high-pressure pulse pump, the cement slurry through the lower end of the drill pipe injection device, to spray around the buried body at a high level , with the impact force of the fluid cutting the soil, so the soil within range jets destroyed, while the drill pipe side of the tunnel at a constant speed rotary jet grouting rig prices, slowly lift one side of the low-speed tunnel Jet rig pile, so the soil body and grout thoroughly mixed, uniform in diameter, with a certain strength of the pile after the formation of hardened cement in the foundation, so that the formation to get reinforced. [Tianjin-strong high-pressure pump Co., Ltd. to recommend the star product] triple tube Jet Grouting Method Which appliances use? (1) The triple-triple grouting grouting pipe assembly pipe assembly: Includes triple grouting tube, triple tube deflectors and triple tube nozzle, spray nozzle. (2) Other appliances ① High pressure hoses (transport jet slurry) generally use wire spiral hydraulic hose, working pressure is not lower than the injection pump. ② pressure air hose (air transport) with 3 to 8 layers of canvas wrapped dipped with an operating pressure above 1.0MPa, diameter φ16 ~ φ32mm.
