What Are The Characteristics of Using A Rotary Drilling Rig To Drive Piles

As a core equipment in modern pile foundation construction, rotary drilling RIGS are widely used in fields such as construction, Bridges, and rail transit, thanks to their efficient and precise operation capabilities. Its unique technical characteristics have significantly improved the quality and efficiency of pile foundation projects. The following is an analysis of its construction features from six aspects:

1. The hole-forming efficiency has been significantly improved: By using a power head to drive the drill pipe to rotate, combined with the rapid up and down reciprocating motion of the telescopic drill pipe, the hole-forming time for a single pile is shortened by more than 50% compared to traditional drilling RIGS, making it particularly suitable for large-scale pile group construction.

2. Wide adaptability to strata: It can be equipped with various drill bits such as short spiral, rotary bucket, and core drill, easily handling clay, sand, gravel layers, and even moderately weathered rock strata, reducing the frequency of equipment replacement caused by geological changes.

3. Highly controllable hole-forming accuracy: Equipped with an advanced electronic control system, through mast verticality monitoring and automatic deviation correction functions, the hole-forming deviation can be controlled within 1%, meeting the strict requirements for pile foundation positioning in high-rise buildings.

4. Environmental protection and low noise advantages: The full hydraulic drive replaces the traditional impact process. The construction noise is lower than 85 decibels, and the amount of slurry used is reduced by more than 60%, effectively reducing the dust and noise pollution to the surrounding environment.

5. Intelligent and convenient operation: The integrated instrument panel displays parameters such as drilling pressure, rotational speed, and depth in real time. The operator can complete complex working condition adjustments through the visual interface, significantly reducing the reliance on manual experience.

6. Prominent comprehensive cost advantage: The average daily hole formation capacity of a single machine can reach 30-50 meters. Combined with mechanical soil unloading, it reduces labor input, and the comprehensive cost is reduced by more than 30% compared with traditional processes. It is particularly suitable for projects with tight schedules and large quantities of work.

Conclusion: The rotary drilling rig, with its characteristics of high efficiency, precision, environmental friendliness and intelligence, has redefined the modern pile foundation construction mode. Its strong adaptability to complex strata and full-process controllability not only enhance the quality and safety factor of the project, but also create significant economic benefits for the project through advantages such as shortening the construction period and reducing energy consumption. With technological iteration, rotary drilling RIGS are developing towards high torque, long pile depth and intelligence, continuously leading the innovation in the field of pile foundation construction.
