Casing Installation Techniques for Hydraulic Core Drilling Rigs
The installation of casing during drilling with portable full-hydraulic core drilling rigs or multi-functional crawler drills requires precision and expertise.
1. Preparing the Borehole
Before inserting the casing, ensure the borehole is free from debris and adequately sized. For rock exploration drilling systems, this preparation minimizes resistance during installation.
2. Driving Methods
Casing can be driven using manual, hydraulic, or percussion methods. Hydraulic driving is preferred for exploration coring drill rigs due to its efficiency and consistency in challenging terrain.
3. Ensuring Proper Alignment
Misaligned casing can lead to equipment damage and inaccurate sampling. Utilizing advanced alignment tools ensures the casing is positioned correctly.
4. Sealing the Casing
For boreholes with groundwater, sealing the casing is essential to prevent inflow. Cement grouting is commonly used, especially in operations involving a multi-functional crawler drill.

Title: Maintenance Tips for Casing in Core Drilling Operations
Regular maintenance of casing ensures optimal performance and longevity of portable full-hydraulic core drilling rigs.
1. Routine Inspections
Inspect the casing for wear, corrosion, or deformation after each drilling cycle. This is particularly important when using multi-functional crawler drills in abrasive environments.
2. Cleaning and Storage
Remove debris and clean the casing thoroughly. Proper storage in a dry environment prevents rust, especially for steel casing used in rock exploration drilling systems.
