1. High construction efficiency

The drilling speed of rotary drilling rig is 15-20 times higher than that of traditional percussion drilling, and it takes only 3-5 hours for a single hole operation, and the mechanised operation reduces the reliance on manual labour, which significantly shortens the construction period.


2. Outstanding environmental performance

Adopting hydrostatic mud wall protection instead of circulating slag discharge, the mud consumption is reduced by more than 70%, and low noise and vibration, which is in line with the requirements of urban environmental protection.


3. Strong geological adaptability

By changing the drill bit quickly, it can cope with clay, sand and gravel, hard rock (strength ≤180MPa) and other strata, even complex strata such as lone rock or pebble gravel.


4. Better hole-making quality

The automatic levelling system of the drilling rig ensures accurate verticality (real-time monitoring by the instrument), the roughness of the hole wall improves the lateral friction resistance of the pile foundation, and the flat-bottomed drilling enhances the bearing capacity of the pile end.


5. Safety and convenient operation

The tracked chassis is highly mobile, no need for lifting assistance; remote control reduces the risk of downhole operation, compared with manual digging, the safety is greatly improved.


6. Controllable comprehensive cost

Although the initial investment is high, the high efficiency shortens the construction period, reduces manpower deployment, and the long-term comprehensive cost is lower than the traditional process, especially suitable for large infrastructure projects.


7. Conclusion

With the core advantages of high efficiency, environmental protection and safety, rotary drilling rig gradually replaces traditional piling equipment and becomes the first choice for bridges, high-rise buildings and complex geological projects, promoting the transformation of infrastructure to mechanisation and intelligence.
