The overburden casing system, meticulously crafted by Changsha Tianhe Drilling Tools and Machinery Co., Ltd., represents a pinnacle of modern engineering. This ingenious technique is indispensable in a variety of drilling operations, including but not limited to water well drilling, anchoring, micro piling, and geothermal engineering. It involves the strategic installation of a casing or pipe, cutting through the complexities of soil, rock, and other materials, thereby ensuring unmatched stability and robust support throughout the drilling process.
Key Features of Our Overburden Casing System:
Changsha Tianhe Drilling Tools and Machinery Co., Ltd. proudly presents our concentric casing system with ring bits, engineered for excellence in challenging geological conditions, including pebble, fissure, dry stone, boulder, and construction backfield waste. This sophisticated system enables precision drilling at various angles while ensuring exceptional straightness, accommodating a maximum hole diameter of 1550 mm with ease.
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
