Operating principle:
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 hoe by means of cement grout or some other sealing agent.
4. Drilling continues to the desired depth in the bedrock using a conventional drilling tools.
Application :
It is suitable for drilling water wells, geothermal wells, short micro-piles, medium mini-type, grouting hole of building & demand harbor project.
