Welcome to Changsha Tianhe Drilling Tools and Machinery Co., Ltd.

 

Product Description: Overburden Casing System

 

An overburden casing system is a specialized technique used in various drilling operations, including water well drilling, anchoring, micro piling, and geothermal engineering. This system involves the installation of a casing or pipe through layers of soil, rock, or other materials to provide essential support and stability during the drilling process.

 

Features:

 

• Ensures stability during drilling operations


• Supports overlying layers of soil and rock


• Prevents collapse and maintains borehole integrity


• Compatible with different drilling applications


 

 

Benefits:

 

• Enhances drilling efficiency


• Reduces the risk of borehole collapse


• Increases overall drilling safety


• Suitable for various geological conditions


 

 

Choose our overburden casing system for reliable support and stability in your drilling projects.

1.When drilling starts,the reamer opens

2.When the drilling is finished,reverse the rotation to close the reamer

3.Keep the casing tube left in the hole,or pull out and pour in grout sealing material

4.Use conventional drilling bits to continue the drilling
