[Tianjin-strong high-pressure pump Co., Ltd. to recommend the star product] High Pressure Jet Grouting Jet Grouting Pile: Department of cement slurry high pressure pump through a special nozzle tip drill, buried the body at a high level jet single fluid injection pump , by means of the impact force of the cutting liquid soil, while the drill pipe side at a constant speed (20r / min) rotation, low-speed side (15 ~ 30cm / min) slowly increase, so the soil thoroughly mixed and solidified grout, form a certain intensity (0.5 ~ 8.0MPa) consolidation cylindrical body (ie jet grouting pile), allowing the foundation to get reinforcement. Features rotating pile are: to improve the shear strength of the foundation; can use small-diameter drill hole rotary jet to be larger than 8 to 10 times as large diameter concretion body, it can be used without disturbing the existing buildings near the foundation reinforcement Construction noise and vibration small;; soil can be used for any soft soil reinforcement range can be controlled; equipment is relatively simple, lightweight variable injection pump, high degree of mechanization; vast new source material injection pump, the construction is simple, fast, low cost. [Tianjin-strong high-pressure pump Co., Ltd. to recommend the star product] single-tube high-pressure grouting Piles is the use of drilling rigs and other equipment, the special nozzle mounted on the bottom side of the grouting tube into the soil after a predetermined depth, a high-pressure mud pump generator to a pressure of about 20Mpa ejected from the nozzle in the slurry out of the direct impact of the destruction of soil, but by the rotation of the grouting pipe and the lifting movement Matsubara injection pump, so that avalanche coming down from the soil soil changes, part of the fine particles with the slurry out of the ground, the rest of the soil particles in the role of impact force jet, centrifugal force and gravity force, and slurry mixing, according to a certain proportion of the slurry and soil quality size, regular re arrangement, after a certain time solidified, it forms a cylindrical body consolidation in the soil.
