Single-tube rotary jet grouting equipment used mainly high-pressure injection pump, jet grouting rig, grouting pipe (bottom with nozzles), transport slurry pipe. 1, high-pressure injection pump is critical equipment, Crawler Jet rig picture, through its high-pressure cutting the soil to make a slurry, to spray the required range, the formation of a certain diameter pile. At present, use of high-pressure pump Co., Ltd. Tianjin strong energy production of special Jet high-pressure injection pump, model: GZB-40C. 2, Jet grouting rig main role is to pipe (on the bottom nozzle) to the design depth, Cangzhou Crawler Jet rigs, lifting and rotating grouting pipe to meet the design requirements. At present, use of Tianjin-strong pile production models XPB-20, XP-50A, SP-30AB, XPL-50 crawler drills. 3, the output slurry pipe to rubber hose or steel pipe inner diameter of the inner diameter of Φ21 Φ19, and able to withstand the pressure of 45MPa or more. Its main role is to connect the high pressure pump and jet grouting rig, triple pipe crawler rotary spray rig, transport slurry. 4, grouting pipe is generally used Φ50 drill pipe, nozzles, nozzle diameter at the bottom with a special general is 2.0mm-3.0mm, the actual use of 2.0mm-2.5mm. Double pipe grouting method is based on the single pipe on the increase in air compressors, gas and water slurry wrapped high pressure cutting soil. All the rig, single and double pipe pile Tianjin-strong company can do, single-tube crawler rotary spray rig, which fully hydraulic models walking XPB-20, track-type XPL-50, single and double triple tube construction can be applied .
