Our factory over-view:
Why choose us?: 1. High quality raw material, with premium hardened procedures for long life. 2. With full production chain to secure stable and prompt production leadtime. 3. Experienced Senior Technicians. 4. Long year experienced workers and engineers. 5. Quick and efficient service. 6. Care customers' concerned. 7. Customized acceptable
APPLICATION RANGE: Widely used for drilling water wells,geothermal wells,short mircoplies,medium mini-type grouting hole of building,damand habour project.
OPERATION GUIDELINES: 1. When drilling starts, the reamer swings out and reams the pilot-hole wide enough for the casing tube to slide down behind the drill bit assembly. 2. When the required depth is reached, rotation is reversed carefully, whereupon the reamer swings in, allowing the drill bit assembly to be pulled up through the casing. 3. Casing tubes that are to be left in the drill hole should be sealed at the bottom of the hole by means of cement grout or some other sealing agent. 4. Drilling continues to the desired depth in the bedrock using a conventional drill string.
