Product Description

Full-Hydraulic High-Pressure Jet Grouting Drilling Rig

Product Description

QXP-80 high-pressure jet grouting drilling rig is a high-performance specialized system for ground improvement, playing a vital role in foundation engineering. It demonstrates exceptional performance in technically demanding projects and complex construction environments.

Applications

1. Wide-Ranging Uses - Applied in soft ground improvement, waterproof curtains for deep excavations, subway tunnel support and anti-flotation anchor construction.

2. Ideal for Key Sectors - Particularly suitable for reinforcement and waterproofing tasks in municipal engineering, rail transit and underground space development.

3. Advanced Technical Capabilities - Capable of single-fluid, double-fluid, and triple-fluid jet grouting methods, with a maximum drilling depth of 100m, standard diameters of φ73mm and φ89mm and flexible 0-90° angle adjustment for complex construction requirements.

Features

1. Modular Auxiliary Mast - Detachable, height-adjustable mast enables single-pass drilling (reducing tool changes) and doubles as a crane for anchor installation, cutting costs.

2. High-Clearance Rotator - 92-mm bore ensures smooth rod passage; hydraulic chuck allows rapid tool changes.

3. High-Torque Powerhead - 11,000 N·m output with reinforced jet grouting tools enables direct penetration in most strata without pilot holes, boosting efficiency.

4. Intelligent Options - Optional drill monitor tracks 11 parameters (grout pressure, volume, lift speed, RPM, etc.); some models feature digital displays for precise quality control.

Advantages

1. High Efficiency - Optimized design significantly reduces non-drilling time and increases overall productivity.

2. Assured Quality - Precision guidance and an optional intelligent monitoring system ensure consistently reliable jet grouting columns.

3. Cost-Effectiveness - Adapts to complex ground conditions while innovative features help lower overall project costs.
