overburden drilling systems with double head;Symmetric Casing Drilling System,

 

Application Range(Top hammer type driling inside the case)   It can be widely used in drilling for grouting holes in projects such as cofferdam,foundation and geolhermal well and etc.

1. firstly,connect the crown opener bit and the outer casing tube,the drill head of the rig impacts the advancing of the outer casing tube,until the completion of the first tube.

2. The inner opener bit is connected with the drill rod,the drill head alongside the bore of the outer tube,until the completion of the first tube.

3. Connect the drill rod and the tube,the drill head of the rig push forward the wxtemal casing tube altogether with the drill rod until the external casing tube is into the desired depth.

4. No need to add any casing tube in the base rock ,only apply with the drill rod to push down to the desired depth.

 

The Double Head Casing Drilling Systems add flexibility to drilling in varying conditions. During drilling, water or compressed air are used as medium, and the discharge head makes the casing tube and drill rod rotate and penetrate. In addition to the benefits of increased flushing control, the inner and outer strings are able to be separately controlled, which greatly increases control over drilling operation. For deeper borehole applications the double casing drilling tools allows for a dual string drilling system with internal flushing, which maximizes the precision to target. The Double Casing Drilling method reduces risk, project time and produces optimal results. It can be widely used in drilling for grouting holes in projects such as cofferdam, foundation and geothermal well and etc.
