High pressure grouting pump for foundation reinforcement

High pressure grouting pump applications: Foundation Reinforcement: Grout fills soil pores to form a composite foundation, increasing bearing capacity. Seepage Prevention and Leakage Repair: Under high pressure, the grout penetrates into micro-cracks, forming a dense curtain to prevent groundwater seepage. Structural Strengthening: Grouting repairs existing building foundation cracks, restoring structural integrity.

Technical advantages of high pressure grouting pump for foundation reinforcement:
1. High pressure penetration capability: An electric motor or diesel engine drives a hydraulic pump to generate high-pressure power. The reciprocating motion of the piston pressurizes the grout to the target pressure (e.g., 50 MPa), easily penetrating dense strata or concrete structures. For example, in sandy and cohesive soils, high-pressure jet grouting piles can form uniform cylinders with a diameter of 1.2 m, significantly improving foundation stability.
2. Precise control and adaptability: Equipped with pressure regulating valves, safety valves, and flow meters, pressure can be monitored in real time and automatically adjusted to adapt to different geological conditions. For example, in quicksand strata, effective sand fixation can be achieved by adjusting the grout pressure (0.2-0.5 MPa) and flow rate (60-80 m³/h).
3. Material compatibility: Flow components are made of stainless steel or special alloys, resistant to chemical grout corrosion; two types of grout (e.g., cement + water glass) can be delivered simultaneously for rapid setting and leak sealing. For example, in humid environments, the combination of modified epoxy resin grout and high-pressure grouting significantly repairs foundation cracks.
4. Portability and ease of operation: Electric lightweight pumps weigh only 6kg, have a power of 560W, and support single-phase AC 220V power supply, making them suitable for indoor repairs; diesel-powered mobile pumps are suitable for tunnel construction, meeting the needs of short-distance chemical grouting.

Typical application scenarios of high pressure grouting pumps in foundation reinforcement:
Soft soil foundation reinforcement: In silt, silty soil, or artificial fill, high-pressure jet grouting technology is used to form a composite foundation by mixing grout with the soil. For example, the Zhuhai Power Plant project solved the problem of reinforcing riprap-filled land through a double-pipe high-pressure jet grouting method.
Existing building repair: Grouting is used to reinforce foundations cracked due to uneven settlement or mechanical damage. For example, in the foundation reinforcement of the office building in Wuwei, Gansu, high-pressure grouting filled soil pores to restore the foundation’s bearing capacity.
Underground engineering seepage prevention: In subway, tunnel, or pump room construction, high-pressure grouting forms a seepage prevention curtain. For example, an office building project in Shenyang used high-pressure jet grouting piles instead of manually excavated bored piles to solve the problem of underground sand inrush, while simultaneously achieving seepage prevention and reinforcement.
Special geological formation treatment: In silty soil or quicksand strata containing gravel, high-pressure grouting can penetrate large-particle media to reinforce the underlying soft soil layers. For example, the Zhuhai power plant project used high-pressure jet grouting piles to penetrate the boulder layer and reinforce the underlying silty soil strata.
