In urban construction and infrastructure upgrades, HDD for water pipe installation has become the preferred method for modern pipeline projects due to its efficiency and environmental benefits. This trenchless technology minimizes ground disturbance, making it ideal for installing water pipes under roads, rivers, and densely built areas.  

1. Key Advantages of HDD for Water Pipe Installation  

(1) Eco-friendly: Eliminates large-scale excavation, preserving vegetation and structures  

(2) High efficiency: Achieves 50-100 meters of daily progress (depending on ground conditions)  

(3) Cost-saving: Reduces overall project costs by over 30% compared to traditional methods  

(4) Precision: Guidance systems ensure ±10cm installation accuracy  

2. Standard Construction Process  

(1) Site survey: Uses ground-penetrating radar to map underground utilities  

(2) Pilot drilling: Creates a φ100mm pilot hole along the designed path  

(3) Reaming: Progressively enlarges the hole to accommodate pipe diameter (up to φ700mm)  

(4) Pipe pulling: Connects HDPE/steel pipes to drill rods for single-pass installation  

3. Critical Equipment Specifications 

(1) Torque requirement: ≥3000N·m (for clay conditions)  

(2) Pull/push force: ≥100KN (ensures long-distance installation)  

(3) Mud system: Flow rate ≥100L/min, pressure ≥4MPa  

4. Recommended Equipment: Hengwang HWF135 HDD Rig

As a professional HDD for water pipe installation solution, the HWF135 features:  

(1) Power: 81kW Cummins engine for 200m continuous operation  

(2) Control: Dual-motor rotary head with 230r/min speed  

(3) Flexibility: Compatible with φ52-60mm drill rods (optional auto-rod handling)  

(4) Adaptability: Rubber tracks minimize ground damage  

This model has successfully completed international HDD for water pipe installation projects including:  

(1) Southeast Asia urban water supply networks (180m single crossing)  

(2) Middle East desert pipeline projects (120m daily progress)  

Expert Tip: When selecting HDD for water pipe installation equipment, verify:  

(1) Contractor's experience with similar geology  

(2) Mud recycling/disposal capabilities  

(3) Manufacturer's technical support availability
