Jet-Grouting (High-Pressure Jet Grouting Pile) Construction Technology

High-pressure jet grouting (jet-grouting method) employs a drilling rig to lower a grouting pipe with nozzles to the pre-determined soil depth. High-pressure equipment injects cement slurry through nozzles at 20-40 MPa to erode the in-situ soil mass. The high-velocity jet cuts and disturbs native soil, forcing cement slurry to mix with broken soil particles. While the grouting pipe rotates and lifts, the mixture hardens into continuous cylindrical consolidated bodies known as jet-grouting piles.

Dynamic Compaction for Soft Ground Improvement: Applicability & Key Application Points

Dynamic Compaction, also known as Dynamic Consolidation, is a highly efficient and cost-effective ground improvement technique. It densifies deep soil layers using the enormous impact energy generated by dropping a heavy weight from a significant height, thereby significantly increasing bearing capacity, reducing settlement, and mitigating collapsibility and liquefaction risks.

Cement Deep Mixing Pile Construction Technology

In soft ground treatment for construction projects, cement deep mixing piles act as a core solution. Using cement as the stabilizer, dedicated machinery thoroughly mixes soft soil with the stabilizer. This process consolidates loose soft soil into a composite foundation with high integrity and good water stability. Widely adopted in buildings, roads, bridges and other projects, it features cost-effectiveness and high efficiency.
