How to Handle Stuck Drill Situations in Rotary Drilling for Building Foundations

Rotary drilling rigs play a vital role in construction projects, especially in foundation works. However, one of the most challenging issues operators face during these projects is the occurrence of stuck drilling. Addressing this issue effectively can save time, reduce costs, and ensure project success.

Understanding the Causes of Stuck Drilling

• Caving of Unstable Soil: During drilling, unstable soil layers may collapse, trapping the drilling equipment.
• Debris Blockage: Accumulated debris can obstruct the drill’s movement.
• Inadequate Lubrication: Insufficient lubrication increases friction, causing the drill to stick.

Prevention Measures

Preventing stuck drilling starts with proper planning and preparation:

• Site Analysis: Conduct thorough geological surveys to understand soil conditions.
• Proper Equipment Selection: Choose rigs like the XCMG Used Rotary Drilling Rig for superior performance in challenging terrains.
• Routine Maintenance: Regularly inspect and maintain equipment to minimize mechanical issues.

Techniques to Handle Stuck Drilling

When stuck drilling occurs, follow these steps:

1. Stop Drilling Immediately: Continuing to operate the drill can exacerbate the situation.
2. Reverse Rotation: Reverse the drill's rotation gently to free it from obstructions.
3. Apply Vibration: Controlled vibrations can help dislodge the drill.
4. Use External Tools: Devices like fishing tools or jacks can be used to retrieve the drill safely.

Case Study: XCMG and SANY Rotary Drilling Rigs

Both XCMG Used Rotary Drilling Rigs and SANY Used Rotary Drilling Rigs are known for their durability and performance. They come equipped with advanced features that reduce the likelihood of stuck drilling, such as:

• Enhanced torque control systems.
• Automatic lubrication mechanisms.
• Real-time monitoring of drilling conditions.

Emergency Preparedness

In case of severe stuck drilling, it is essential to have a recovery plan:

• Contact Experts: Seek help from experienced technicians.
• Equipment Replacement: Be ready to deploy backup equipment.
• Training: Regular training sessions for operators on handling such emergencies.

By following these guidelines and using reliable equipment like the SANY Used Rotary Drilling Rig, construction teams can minimize the risks and impact of stuck drilling.
