Casing Advancement Systems for Overburden Drilling

Rock Drilling Tools

Casing Advancement Systems

Drilling systems for casing advancement in overburden formations

Casing advancement systems combine the high penetration efficiency of down-the-hole hammer drilling with simultaneous casing installation. This approach improves drilling efficiency, reduces overall construction costs, and is widely applied in mine shafts and drifts, slope stabilization, geological hazard mitigation, dam foundation reinforcement, deep excavation support, structural uplift and overturning resistance, as well as cofferdam seepage control projects.

Eccentric Casing Drilling System

Eccentric casing drilling systems are designed for overburden drilling where borehole collapse or instability may occur.

Concentric Casing Drilling System

Concentric casing drilling systems with ring bits, wings, and blocks are designed for stable casing advancement in complex ground conditions.

Casing Pipes

The casing body is manufactured from high-quality R780 or P110 steel, while the threaded joints are made of premium 42CrMo alloy steel.

Reverse Circulation Connection Adapters

Casing shoes are designed for casing-supported drilling operations to stabilize borehole walls in foundation piling and water well projects.

In pile casing installation and diaphragm wall construction, how adaptable and efficient are casing advancement systems in very soft or complex mixed overburden formations?

This series of casing advancement systems integrates anti-collapse and anti-sticking performance with quick assembly and disassembly. ODEX and three-wing casing shoe systems can be flexibly selected to effectively handle loose formations and gravel interlayers, enabling rapid casing installation and high borehole success rates.

During frequent site relocation or subcontracted operations, can casing shoes and drill bits be replaced independently on site?

Quick-release threaded connections and positioning rings are incorporated into the design, allowing casing shoes and drill bits to be replaced independently without returning to the workshop, significantly reducing downtime and waiting periods.
