Which Should Be Chosen, Rotary Drilling Piles Or Perforated Piles

In engineering construction, rotary drilling piles and perforated piles are commonly used foundation construction methods, and many people are confused about how to choose between the two. Below, we will provide you with a detailed comparison from six aspects to help you quickly find the answer.

1. Construction efficiency: The rotary drilling rig uses a rotary drill bit to take soil, with an extremely fast hole formation speed. It can complete 3 to 5 piles in a day. However, perforated piles rely on the repeated impact of impact hammers to form holes, which is much less efficient than rotary drilling piles. Under the same conditions, only one pile may be completed in a day.

2. Applicable geology: Rotary drilling piles perform well in soft soil layers such as clay and silt, but they struggle when encountering hard rocks. Perforated piles, with their powerful impact force, can easily handle rock and gravel layers and are suitable for complex geological conditions.

3. Environmental performance: Rotary drilling piles use static mud for wall protection, and the mud is recycled, generating less waste. During the impact process of perforated piles, significant noise and mud overflow will be generated, which has a greater impact on the surrounding environment.

4. Pile quality: Rotary drilling piles have high hole-forming accuracy, regular hole walls, and can effectively control the verticality of the pile body. During the impact process, perforated piles are prone to uneven hole walls, and the difficulty of hole cleaning is also relatively high.

5. Equipment cost: The purchase and rental costs of rotary drilling RIGS are high, and the initial investment is large. Perforated pile equipment is relatively simple and has a low cost, making it suitable for projects with limited budgets.

6. Personnel Requirements: The operation of rotary drilling piles requires professional technicians, and the skills of the operators are highly demanded. The operation of perforated piles is relatively simple, and ordinary workers can master it after training.

In conclusion, when choosing between rotary drilling piles and perforated piles, factors such as the project duration, geological conditions, environmental protection requirements, and cost budget need to be comprehensively considered. If high efficiency, environmental protection and suitable geological conditions are pursued, rotary drilling piles are the preferred choice. If faced with complex geological conditions and limited budget, perforated piles might be more suitable.
