Advantages of Rotary Drilling Rig And Screw Drilling Rig

1. High drilling efficiency: the rotary drilling rig has sufficient power and large torque, and the single drilling depth is far more than that of the screw drilling machine, which can quickly complete a large number of drilling and greatly shorten the construction period.

2. Strong geological adaptability: After replacing the drilling tool, the rotary drilling rig can cope with a variety of geology such as soft soil, sand layer, gravel layer and even medium weathered rock layer. Auger RIGS have difficulties when working in complex hard formations.

3. Good hole quality: rotary drilling rig relies on electronic control system to accurately control the verticality and aperture of the drilling hole, smooth hole wall and regular shape, which is conducive to subsequent steel cage placement and concrete pouring. The hole deviation of auger drilling machine is easy to occur.

4. Excellent environmental performance: the rotary drilling rig has less mud consumption and is convenient for centralized processing, and the construction site is cleaner and reduces environmental pollution. During the operation of auger, soil debris spatter and mud are difficult to control.

5. High degree of automation: rotary drilling rig has a high degree of intelligence, with automatic positioning, drilling, lifting functions, the operation is concentrated in the cab, reducing labor intensity and risk. Auger automation level is low.

6. The equipment is convenient to move: the tracked chassis of the rotary drilling rig makes it flexible to move, can quickly change fields and adapt to complex terrain. Auger movement often requires more auxiliary equipment.

7. Conclusion: Compared with auger, rotary drilling rig has obvious advantages in drilling efficiency, geological adaptability, hole forming quality, environmental protection, automation, equipment movement, etc., which provides guarantee for efficient and high-quality construction of pile foundation projects.
