The following is a professional description of water jet drilling high-pressure cleaning machines.
1. Core Definition
Water jet drilling high-pressure cleaning machines are specialized equipment used for pre-drilling pre-pile foundation construction. They use ultra-high-pressure water jets to break up rock and soil layers, creating pre-drilled holes. This replaces traditional mechanical drills and is suitable for use in complex geological conditions.
II. Working Principle
Power System
Diesel engine drives booster pump to generate ultra-high-pressure water flow
Pressure adjustment range: ±50 bar (adjusted in real time based on rock and soil hardness)
Injection System
Diamond nozzle (aperture diameter 0.5-1.2 mm) focuses the water flow
Hole piloting
Start with low-pressure (500 bar) hole positioning
Layered pressure increase to target pressure (adjusted every meter)
Quality Inspection
Hole verticality deviation <1%
Hole wall free of spiral marks (water flow stability test)
V. Safety Enhancements
Splash prevention: Three-stage baffles installed (refer to the chemical equipment cleaning standards you have previously learned about)
Hole collapse prevention: Real-time injection of stabilizing fluid (bentonite solution)
Emergency shutdown: Two-button linkage control (interval ≥ 1.5 meters)
