Rotary Jet Cement Grout Pump is a professional equipment used for high-pressure rotary jet grouting construction. It combines rotary drilling and high-pressure jet grouting technology and is widely used in engineering fields such as foundation reinforcement, anti-seepage curtain, and soft soil foundation treatment. In the high-pressure rotary jet grouting process, the rotary jet cement grouting pump delivers cement slurry to the nozzle at the end of the drill pipe through high pressure. At the same time, the drill pipe rotates and lifts at the same time, and the slurry sprayed from the nozzle at high speed cuts and mixes the surrounding soil to form a columnar or wall-shaped reinforcement body.
Plunger jet grouting pump working principle: Plunger reciprocating motion: The plunger reciprocates in the pump cylinder, changing the sealed volume to achieve the suction and discharge of slurry. High-pressure injection: The slurry is pressurized to more than 20MPa through a high-pressure pump and ejected at high speed through a nozzle, impacting and destroying the soil and forming a consolidated body.
Jet Pump Grout Systems pressurizes the grout to more than 20MPa and ejects it at high speed through the nozzle. The high-speed jet impacts and destroys the soil, and the grout mixes with the soil particles. After the mixture solidifies, it forms a cylindrical, plate-shaped or wall-shaped consolidation body to improve the foundation strength or achieve anti-seepage.
Different projects have different requirements for grouting pressure, flow rate, and shape of the solidified body, and appropriate equipment should be selected according to the specific project conditions. For example, for projects that need to form a solidified body with a larger diameter, equipment with higher injection pressure and larger injection flow rate can be selected; for projects that need to form a solidified body with a specific shape, a Jet Grouting Pump that can control the direction of the jet flow can be selected.
Jet grouting equipment for drilling grouting application: Foundation reinforcement: improve the strength of building foundation, protect adjacent buildings during foundation pit excavation, protect bridge pier foundation, strengthen the back seat of shield method and jacking method, stabilize the excavation surface of mines, subways, tunnels and pipeline trenches, prevent soil landslides, protect docks and embankments, correct deviations, etc. Seepage prevention and leakage control: prevention and control of foundation leakage of embankments, dams, gates, bridges, etc., seepage prevention and control of various foundation pits and underground structures, prevention and control of sand liquefaction, reduction of foundation vibration, treatment of roadbed slurry, remediation of underground anti-seepage walls, prevention of sandblasting and water gushing, etc.
The high pressure triplex pump consists of three parallel plungers or pistons, which are driven by a crankshaft to achieve reciprocating motion. The three-cylinder design can significantly reduce pressure pulsation, make fluid delivery more stable, and improve grouting efficiency. The triplex grout pump can generate pressures of up to 450 bar, which is suitable for deep grouting or high-viscosity grout delivery. By adjusting the pump speed or plunger stroke, the grouting flow rate can be flexibly controlled to meet the needs of different working conditions.
For high-pressure rotary jet grouting (High-Pressure Jet Grouting, commonly referred to as high rotary jet grouting), the cement grout pump is a critical piece of equipment that must meet specific performance requirements due to the high pressures involved. This method involves injecting cement slurry at very high pressure through a nozzle in a rotating drill rod to erode and mix with the soil, forming a column of improved ground.
