[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, buy jet grouting pile, the special nozzle mounted on the bottom side of the grouting tube placement After a predetermined depth of soil, mud pump and other high-pressure generating device, 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 promotion campaigns to avalanche down from the soil The earth 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, sunshine spin spray pile, regularly rearranged solidified after a certain time, they form a cylindrical body consolidation in the soil. Triple pipe high pressure rotary jet grouting pile reinforcement principles and methods of rig operations by a special triple injection tube, the injection tube ends three nozzles respectively eject high pressure water, compressed air and water slurry. The jet from the high pressure water and compressed air to cut the soil formation, ejection by another nozzle of the grout mixed with the soil to be cut to form cement, soil mix, achieve the purpose of Reinforced Earth. Since the injection tube spray rig operations side, while rotating, twin jet grouting pile, while improved, thereby forming a cylindrical soil has a high strength cement plus solid, called jet grouting piles. If side injection side upgrade without rotating, then mix in the soil cement and soil implemented within the scope of the sheet.
