Ensuring Borehole Cleaning Quality in Rotary Drilling

Proper borehole cleaning is critical after rotary drilling to ensure the success of pile foundation construction. Advanced rigs like the XCMG Used Rotary Drilling Rig and SANY Used Rotary Drilling Rig enable effective cleaning and quality detection.

The Importance of Borehole Cleaning Quality

Cleaning boreholes ensures:

• Foundation Stability: Removes debris and slurry for solid pile foundations.
• Better Concrete Bonding: Enhances adhesion between concrete and soil.
• Regulatory Compliance: Meets construction standards and inspection requirements.

Challenges in Cleaning Quality Detection

Key challenges include:

• Residual Slurry: Difficult to detect and remove completely.
• Deep Boreholes: Increased difficulty in accessing the bottom for inspection.
• Time Constraints: Ensuring thorough cleaning without delaying the project.

How Rotary Drilling Rigs Support Cleaning

The XCMG Used Rotary Drilling Rig and SANY Used Rotary Drilling Rig assist in maintaining cleaning quality through:

• High-Precision Monitoring Systems: Ensure boreholes are free from debris and slurry.
• Efficient Cleaning Tools: Enable effective removal of residue at all depths.

Techniques for Borehole Cleaning Quality Detection

Key methods include:

1. Slurry Density Testing: Verify slurry removal using monitoring tools on the XCMG Used Rotary Drilling Rig.
2. Video Borehole Inspection: Use cameras to check for residual debris.
3. Cleaning Fluids Analysis: Assess the cleanliness of returned fluid.
4. Depth and Diameter Validation: Ensure borehole dimensions are maintained post-cleaning using SANY Used Rotary Drilling Rig systems.
