Triple pipe high pressure rotary jet grouting pile reinforcement methods and principles of special triple rig operations by the injection tube, the injection tube ends by the three nozzles, Beichen injection pump, high-pressure water jet, respectively, compressed air and water slurry. The jet from the high pressure water and compressed air to cut the soil formation, piston injection pump, grout injected from another soil mixing nozzles and cleaved to form cement, soil mix, grout injection pump, to strengthening The purpose of soil. Since the injection tube spray rig operations side, while rotating, 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. [Tianjin-strong high-pressure pump Co., Ltd. to recommend the star product] What is double-tube method? Double tube method is to use a double grouting pipe dual channel. When double-grouting pipe drilling to a predetermined depth of soil after the anchor hole injection pump, via a coaxial double nozzle in the side of the bottom of the tube while spraying a slurry and high pressure jet impingement air destruction of two medium earth body. That high-pressure mud pump high-pressure generating device is ejected slurry 20KPa so, from high-speed spray nozzle, and use about 0.7KPa pressure compressed air is ejected from the outer nozzle. High pressure in the joint action of the slurry and its outer airflow, energy destroy the soil increases significantly, the final form of the larger consolidated body in the soil.
