[Tianjin-strong high-pressure pump Co., Ltd. to recommend the star product] Churning Pile (plus solids) can be used for existing buildings and new construction foundation reinforcement, triple pipe jet grouting pile, deep excavation, subway and other projects of soil reinforcement or waterproof. In the Pit Protection Engineering mostly given in the form of spray or spray swing as impermeable walls alone or in combination with anti-volt row pile combined (do directional swing between piles spray) is used as a retaining wall seepage. 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, 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 high-pressure injection pump jet grouting, jet grouting pile Hebei, model: GZB-40C. 2, Jet grouting rig main role is to pipe (on the bottom nozzle) to the design depth, jet grouting pile picture, lifting and rotating grouting pipe 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, 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.
