Product Description

Product Description

 

Overburden casing system typically refers to a technique used in certain types of drilling operations, such as in water well drilling,anchoring,micro piling or geothermal engineering. It involves the installation of a casing or pipe through overlying layers of soil, rock, or other materials to provide support and stability during the drilling process.

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

    1.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.

 

    2.Anchoring
    Eccentric casing system(ODEX) can meet the requirements of anchoring projects better when reinforcing the slope.

 

    3.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.

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.
