Product Overview
- Our 220L/min 240Bar Water Jet Pilot-Hole Piling Equipment is a professional high-pressure water jet assisted piling machine built for complex pile foundation engineering. Combining high-pressure water jet rock breaking and large-flow debris removal functions, this water jet pilot-hole piling system solves major construction pain points that traditional piling rigs face in hard and complicated ground conditions.
- It is widely used for pre-drilling and auxiliary piling work of steel sheet piles, steel pipe piles, and H-beam piles, supporting underground projects including deep foundation pits, municipal urban construction, highway and bridge infrastructure.

Core Performance & Working Principle
This water jet pilot hole piling equipment adopts the core working principle: high-pressure water jet pretreatment + precise pile placement. It leverages the combination of 240Bar high pressure and 220L/min large flow rate to achieve low-resistance, efficient piling operations.
- High-Pressure Cutting & Splitting:
- The matched 500Bar high-pressure water jet forms a dual effect of water wedge splitting and erosion stripping on stiff plastic clay, dense sand, fully weathered rock, and gravel layers. It effectively softens and breaks hard soil layers that traditional piling equipment cannot penetrate.
- High-Flow Slag Cleaning:
- The 300Lpm super large flow rate quickly washes away borehole debris, completely eliminating common failures of traditional construction such as rotary friction of drill pipes and hard contact jamming of impact drilling.
- Low-Resistance Pile Sinking:
- Pre-treat and soften the stratum through high-pressure water jets in advance, fundamentally reduce pile sinking resistance, and enable smooth and vertical pile penetration.
Key Product Advantages
- Ultra-High Construction Efficiency
- Traditional hammer or vibratory piling meets slow progress and low productivity in dense sand, hard clay and gravel strata. Our water jet pilot-hole piling equipment optimizes the whole construction workflow. After high-pressure water jet pre-drilling, overall piling efficiency rises by 50%-100%, speeding up pile sinking and shortening project timelines.
- Effective Pile Body Protection
- Traditional impact hammer piling relies on heavy impact force, which easily bends, deforms or fractures steel sheet piles, H-piles and steel pipe piles. Our high pressure water jet assisted piling machine cuts and softens strata beforehand, removing the need for violent impact. It protects pile integrity and guarantees foundation construction quality.
- Low-Noise & Green Construction
- Unlike conventional hammer piling that generates heavy noise pollution, the water jet pilot hole piling system runs with low noise and low vibration. It minimizes disturbance to nearby residents and surrounding environments. Perfect for urban core zones and residential areas with strict noise limits, ideal for modern prefabricated building foundation projects.
- Energy-Saving & Cost-Effective
- By lowering piling resistance, this water jet pilot-hole piling equipment reduces the required static pressure force for static piling or hammer energy for impact piling, saving energy. It also avoids extra costs caused by pile damage and repeated construction. Construction costs stay unchanged while productivity improves, bringing better ROI for contractors.
Wide Application Scenarios
With the global adoption of green prefabricated building technology, prefabricated steel piles have become the preferred option for underground foundation works. Our high pressure water jet assisted piling machine adapts to many tough working conditions:
- Deep foundation pit projects for urban buildings
- Deep foundation pit projects for urban buildings
- Highway, bridge and municipal infrastructure piling
- Steel sheet pile, steel pipe pile and H-beam pile installation
- Complex strata: dense sand, stiff plastic clay, gravel and fully weathered rock
- Urban construction sites with strict noise & environmental protection requirements
