Eccentric Overburden ODEX90 - ODEX280 Drilling Casing Systems
Product Specification:
Eccentric Reamer System Step-by-step
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.
