Rotary jet grouting injection pump is one of the core equipment in high-pressure rotary jet grouting technology. It is mainly used to transport cement slurry under high pressure to the nozzle at the end of the drill pipe, and cooperate with the rotation and lifting of the drill pipe to form a uniform reinforcement column in the formation.

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.

By adjusting the pump speed or plunger stroke, the grouting flow rate can be flexibly controlled to meet the needs of different working conditions.
