How efficient are trenchless drilling machines?
Aug 21, 2025| I. Construction Efficiency Comparison
1. Horizontal Directional Drill
200-meter pipeline crossing completed in just 6 hours (traditional excavation takes several days)
Suitable for municipal projects, avoiding damage to newly built roads and green spaces
2. Fence Drill
Drilling time per hole: 3-5 minutes (18-25 minutes for manual drilling), 2-6 times higher efficiency
80-100 holes completed per day (30 for manual drilling)
3. Bracket-Mounted Diesel Drill
Drilling time per hole: 25 minutes (1 hour and 45 minutes for manual drilling), 4 times higher efficiency
35 holes completed per day (8 for manual drilling), 50% lower overall costs
II. Key Factors for Efficiency Improvement
1. Mechanized Power
Diesel Drill Rig: 15 hp Power engine + alloy drill bit significantly increases speed.
A spiral drill bit design reduces resistance in hard soil (e.g., the GLP-150 drill has a torque of 7840 N·m).
2. Intelligent Guidance Technology.
Magnetic compass accuracy is ≤1 meter per 100 meters, reducing correction time.
3. Standardized Operation.
Single-operator operation reduces labor reliance (e.g., the average daily wage for a diesel driller is 300 yuan).
III. Typical Application Scenarios.
1. Municipal Engineering.
Horizontal directional drilling rigs for pipeline crossings (e.g., the GLP-150 drill rig reaches a depth of 50 meters).
2. Fence Reinforcement.
The drill rig completes an average of 200 holes per day (requiring 4 people for 3 days).
3. Foundation Reinforcement.
The verticality error of the bracket-type drilling rig is ≤1°, providing superior quality compared to manual drilling.
