The Difference Between Pile Driver And Rotating Drill

1. The application is different:

Rotating drill: it is used for drilling the rock strata with the hardness coefficient F ≤6 in open-pit mines, and it can also drill the hard interlayer rocks with F =7-11. Rotary torque and axial pressure are applied during drilling to cause the bit to rotate and feed to cut through rock.
Pile driver: suitable for building foundation engineering in the construction of hole operation machinery. Mainly suitable for sand soil, cohesive soil, silty soil, and other soil layer construction, in the cast-in-place pile, continuous wall, foundation reinforcement, and other foundation construction is widely used.

2. Different characteristics:

Rotating drill: Hydraulic crawler type telescopic chassis, self-lifting, and collapsible drill mast, telescopic drill pipe, with vertical automatic detection and adjustment, digital display of hole depth, etc., the whole machine generally adopts hydraulic pilot control, load sensing, with the characteristics of light and comfortable operation.
Pile driver: the use of hydraulic crawler type telescopic chassis, self-rise and fall collapsible drill mast, telescopic drill pipe, with vertical automatic detection and adjustment, hole depth digital display, the machine is generally operated by hydraulic pilot control, load sensing, with the characteristics of light and comfortable operation. The main and secondary winches can be applied to various situations in the construction site.

3. The development of different:

Rotating drill: in high-rise buildings, ports, DAMS, Bridges in the foundation engineering of large diameter bored piles construction, using rotary drilling rig drilling filling pile construction is convenient, safe and reliable operation, strong adaptability, low cost, high efficiency, and good stability of hole wall into a hole, etc, the construction of construction organization and management, with reasonable for bored pile construction can play a better role of propulsion.
Rotating drill: it has obvious advantages in the construction of bored piles in subway engineering and strong applicability; High degree of automation, low labor intensity; High drilling efficiency; Good pile quality; Small environmental pollution. It can significantly improve the construction efficiency and quality of the project. The reasonable selection of construction methods and construction technology can maximize the saving of material resources, financial resources, human resources.
