Product Description
Overburden casing system commonly denotes a methodology employed in specific drilling operations, such as water well drilling, anchoring, micro piling, or geothermal engineering. This technique involves the installation of a casing or pipe through successive layers of soil, rock, or other materials that lie above the target zone. The primary purpose of this casing system is to provide essential support and ensure stability throughout the drilling process. By penetrating and securing the overlying
layers, it prevents cave-ins, collapses, or other undesirable occurrences, thus facilitating safer and more efficient drilling operations. This method plays a crucial role in maintaining the integrity of the borehole, protecting it from potential structural damage, and allowing for the extraction of desired resources or the implementation of various engineering applications.

Here's a general overview of how an overburden casing system works:
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 |

Applications
Water well drilling
Eccentric casing system(ODEX) is the main drilling tools in water well projects,which can keep drilling the hole and protecting it from caving in the same time.And it can significantly reduce the drilling time when drilling through the overburden.
Anchoring
Eccentric casing system(ODEX) can meet the requirements of anchoring projects better when reinforcing the slope.
Micro piling
In soil,clay and sand rock formations.eccentric casing system is the most economic and fastest in protecting the hole from
collapsing with permanent or temporary casing tubes.
collapsing with permanent or temporary casing tubes.

Other Casing Tools
Concentric casing system with ring bits
It is suitable for overburden with complex geological conditions, such as pebble, fissure, dry stone, boulder, construction backfield waste, etc. It can be drilled at any angle with high straightness.
The maximum diameter of the hole can reach 1550 mm.
Concentric casing system with blocks
1.The material of joint tools is better than casing tube and after heat treatment, the connection is reliable.
2.The casing shoe is heat-treated to extend the service life.
3.The blocks and locking kit are strengthened and have good comprehensive performance
4.Application fields: pile foundation engineering, slope support engineering
Concentric casing system with wings
It is suitable for covering layers with loose materials, such as soil, clay, weathered rock, and sand particles.
