The Differences between Rotary Drilling Rig Pile Driving And Manual Pile Digging

In the field of pile foundation construction, rotary drilling rig pile driving and manual pile excavation are two common methods. There are significant differences between the two in terms of efficiency, applicable scenarios, etc. The following is an analysis from six dimensions.

1. Construction efficiency: Relying on mechanical power, rotary drilling RIGS can complete piles ranging from several meters to tens of meters in a single day, making them suitable for large-scale projects. Manual pile digging is limited by physical strength, and the daily progress is usually less than 1 meter, which is only suitable for small-scale projects.

2. Applicable geological conditions: Rotary drilling RIGS can handle complex strata such as hard soil and rock layers, and adapt to various geological conditions through different drilling tools. Manual pile excavation is prone to collapse in soft soil and quicksand layers, and has high requirements for geological stability.

3. Degree of safety risk: When the rotary drilling rig is in operation, personnel should stay away from the pile hole to reduce risks such as collapse and harmful gases. Manual pile digging requires personnel to go deep into the mine, which poses safety hazards such as falling objects and suffocation, and the protection is difficult.

4. Pile quality accuracy: The rotary drilling rig mechanically controls the verticality and diameter of the borehole, with relatively small errors and good integrity of the pile body. Manual pile excavation is prone to problems such as uneven hole diameters and verticality deviations due to the influence of operational experience.

5. Labor cost input: A rotary drilling rig requires 1-2 operators, with low and stable labor costs. Manual pile digging requires multiple people to take turns working, which not only incurs high costs but is also affected by the mobility of personnel.

6. Environmental impact performance: The rotary drilling rig generates relatively high noise during operation, but it is highly controllable. When combined with dust suppression equipment, pollution can be reduced. Manual pile excavation is quiet, but the transportation of soil and the disposal of waste residue can easily cause the site to become messy.

In conclusion, rotary drilling RIGS are more suitable for large-scale and complex geological engineering projects, with the advantages of high efficiency, safety and high quality. Manual pile excavation still has application space in small and simple geological scenarios, but its comprehensive efficiency has gradually been replaced by mechanical construction. When making a choice, the scale of the project, geological conditions and cost budget should be comprehensively considered.
