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, sealing curtain pile driver manufacturers, jetted from another nozzle of the grout is mixed with soil to be cut, double tube sealing curtain pile to form cement, soil mixture to achieve the purpose Reinforced Earth. Since the jet side of jet pipe rig operations, following a sealing curtain pile works, while rotating, while improved, Hongqiao sealing curtain pile to form a cylindrical soil has a high strength cement plus solid, known as Jet piles. If side injection side upgrade without rotating, then mix in the soil cement and soil implemented within the scope of the sheet. High pressure spraying pile is high pressure rotating nozzles grout is injected into the soil and the soil mixed to form a continuous lap of cement and solid. Construction area of ??small, low vibration, low noise, but easy to pollute the environment, high cost, not for special slurry solidification of the discharged soil should not be used.
