What Causes Pile Breakage in Rotary Drilling? 3 Key Factors You Must Know - hnironrubikcubemachine.com

Pile breakage is a frequent challenge in rotary drilling rig construction. Whether using an XCMG used rotary drilling rig or a SANY used rotary drilling rig, understanding the root causes of pile breakage is crucial for preventing costly delays. Here are three primary factors that contribute to this issue.

1. Poor Soil Conditions

Unstable or mixed soil conditions can exert uneven pressure on the pile, leading to fractures. Operators of Second-hand rotary drilling rig should always conduct a thorough ground survey before drilling.

  • Cause: Loose or rocky soils increase stress on the pile.
  • Solution: Use stabilizing techniques such as casing or bentonite slurry.

2. Excessive Drilling Pressure

Applying excessive force when drilling can cause unnecessary stress, weakening the pile’s structural integrity. This is a common issue in SANY used rotary drilling rig operations.

  • Cause: High axial pressure on the pile.
  • Solution: Maintain moderate pressure to ensure smooth penetration.

3. Inadequate Reinforcement and Material Quality

Poor-quality concrete or steel reinforcements can cause the pile to crack under load. Reconditioned rotary drilling rig users should always verify material strength before beginning construction.

  • Cause: Low-quality materials or improper reinforcement placement.
  • Solution: Use high-grade steel bars and optimized reinforcement layouts.

Conclusion

By understanding these three factors, operators of XCMG used rotary drilling rig and SANY used rotary drilling rig can take preventive measures to minimize pile breakage risks. Ensuring proper drilling techniques and material selection will lead to more stable and successful projects.
