Why Does Pile Breakage Happen in Rotary Drilling? 3 Crucial Mistakes to Avoid - hnironrubikcubemachine.com

Pile breakage during rotary drilling rig construction can lead to project delays and increased costs. Understanding and avoiding these common mistakes is essential, whether you're using an XCMG used rotary drilling rig or a SANY used rotary drilling rig. Here are three major mistakes that often result in pile breakage.

1. Using Inadequate Drilling Techniques

Incorrect drilling techniques can exert excessive stress on the pile, causing fractures. Second-hand rotary drilling rig operators must ensure their drilling approach is suitable for the soil and pile material.

  • Mistake: Applying too much torque or drilling at an incorrect angle.
  • Solution: Adjust rotation speed and use the proper drilling alignment.

2. Ignoring Reinforcement Requirements

Failing to use the correct reinforcement materials weakens the pile structure, making it susceptible to cracking. SANY used rotary drilling rig users should always verify that reinforcement bars are correctly placed.

  • Mistake: Poor-quality reinforcement or improper spacing.
  • Solution: Follow engineering specifications and use high-grade materials.

3. Neglecting Soil Stabilization

Unstable soil conditions can shift during drilling, putting additional stress on the pile. Reconditioned rotary drilling rig operators should stabilize the ground before starting excavation.

  • Mistake: Drilling in soft or loose soil without prior stabilization.
  • Solution: Use casing or grout injection to strengthen the soil.

Conclusion

By avoiding these critical mistakes, operators of XCMG used rotary drilling rig and SANY used rotary drilling rig can significantly reduce the chances of pile breakage. Proper techniques, material selection, and ground preparation ensure stable and efficient drilling operations.
