What Power of Rotary Drilling Rig Can Drive High-speed Bridge Piles

Friend, in the construction of high-speed bridge piles, choosing the right power of the rotary drilling rig is of vital importance. The power is too small to cope with complex geology. Excessive power will also lead to cost waste. What power of rotary drilling rig is suitable for driving high-speed bridge piles? Let's have a detailed discussion from these six aspects.

1. Check the diameter of the pile: Generally speaking, for bridge piles with a diameter of 1.5 meters or less, a rotary drilling rig with a power of 200-280 KW is basically sufficient. If the diameter of the pile exceeds 2 meters, a power of more than 300kW is required to provide sufficient torque and drilling force.

2. Consider the requirement for pile depth: The pile depth should be around 30 meters, and a power of 220-260 kW is acceptable. However, if the pile depth exceeds 50 meters, a rotary drilling rig with a power of 360kW or even higher must be selected to ensure that the designed depth can be reached.

3. In combination with geological conditions: In soft soil layers such as clay and sandy soil, a power of 200-240 kW is sufficient. If it comes into contact with hard strata such as rock layers and pebble layers, at least 300kW of power is required to have the ability to break.

4. Pay attention to construction efficiency: To speed up the construction progress, a rotary drilling rig with high power has more advantages. For equipment with a power of over 300kW, the hole-forming efficiency per hour is 30% to 50% higher than that of low-power equipment.

5. Equipment configuration coordination: High-power rotary drilling RIGS also need to be matched with powerful power heads and drill pipes. For instance, a 360kW drilling rig needs to be equipped with a high-torque power head and high-strength drill pipes to achieve its best performance.

6. Budget cost trade-off: The purchase and operation costs of high-power rotary drilling RIGS are higher. Under the premise of meeting the construction requirements, a comprehensive assessment can be made to select the power model with high cost performance and avoid excessive investment.

When choosing the power of a rotary drilling rig suitable for driving high-speed bridge piles, multiple factors such as pile diameter, pile depth, geology, efficiency, equipment configuration and cost should be comprehensively considered. Precise matching of power can not only ensure the quality and efficiency of high-speed bridge pile construction, but also control costs and facilitate the smooth progress of the project.
