Jet grouting rig main role is to pipe (on the bottom nozzle) to the design depth, to meet the lifting and rotating grouting pipe design requirements. At present, use of Tianjin-strong pile production models XPB-20, XP-50A, SP-30AB, XPL-50 crawler drills. [Tianjin-strong high-pressure pump Co., Ltd. to recommend the star product] single pipe high pressure rotary jet pile control 1, according to the duration and other design work and combine predisposition, drawn into the machine, Shuangyashan high pressure jet grouting rig, depending on site conditions adjustment. Appoint management staff responsible for safe construction, preparation of a good machine number, water-cement ratio, pile length and other signs made clear unified hanging hold to pile the specified location. 2, before the jet grouting, high pressure jet grouting rig type, to check high-voltage equipment and piping systems. Pressure and displacement devices must meet the design requirements, the use of high-pressure pumps, high pressure jet grouting rig manufacturer, the determination to deal with the safety valve, high pressure jet grouting rig a set amount of money, its operation must be reliable. Seal piping system must be well, may not have within each channel and nozzle debris, clean with water slurry feed pipe, check for clogging, ensure proper construction.
