Customized screw pile driver excavators and deep hole drilling rigs for pile foundation excavation, suitable for utility pole pits, tree planting holes, photovoltaic power station support holes, and pile foundation holes in construction projects.
Project Description
Core Concept: A hydraulic-driven auger attachment that utilizes spiral blades for rapid drilling, designed for quick installation on construction machinery such as excavators and loaders.
Primary Components: Typically consists of a hydraulic power head, auger shaft, and mounting bracket.
Working Principle: The power head generates torque to rotate the auger shaft and drill bit; the drill bit cuts through soil, which is then transported to the surface via the spiral blades.
Typical Applications: Utility pole holes, tree planting pits, photovoltaic power station support holes, pile foundation holes in construction projects, etc.
Key Advantages
- Efficient & Flexible: Rapid drilling with easy relocation
- Multi-Functional: Quick interchangeability with other attachments (e.g., buckets)
- Versatile Adaptability: Operates across diverse terrains (hills, mountains) and most soil types
Key Drawbacks
- Limited Drilling Depth: Typically under 10 meters, significantly less than rotary drilling rigs
- Terrain Restrictions: Challenges in hard rock or pure sand layers
Differences from Other Drilling Machines
Understanding the distinctions between auger drills and functionally similar rotary drilling rigs or down-the-hole drills aids in precise equipment selection:
Auger Drills:
Core strengths lie in flexibility and efficiency, suitable for diverse shallow, small-to-medium diameter drilling tasks—a highly versatile “jack-of-all-trades.”
Rotary Drilling Rig:
A large, specialized standalone machine primarily used for large-diameter, ultra-deep hole formation in foundation engineering, such as bridge pile foundations. It achieves drilling depths of 60-90 meters and diameters of 1.5-4 meters, but its bulkiness limits mobility.
Down-the-hole drill rig:
Specialized for drilling hard rock formations. It employs a percussion hammer submerged at the bottom of the borehole to fracture rock, finding extensive application in mining and rock excavation.
How to Choose
For projects like utility pole installation, tree planting, or solar projects requiring frequent, rapid shallow hole drilling (within a few meters) at multiple sites, equipping an excavator with an auger rig is a highly efficient and economical choice.
For projects involving large-diameter, ultra-deep pile foundations, a dedicated rotary drilling rig should be considered.
If drilling primarily in hard rock, a down-the-hole drill is the appropriate tool.
