Product Description

Slide Block Casing system

Slide Block Casing System/Casing shoe for well drilling

Working 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 Range

It is suitble for drilling water wells, geothermal wells, short mircopiles, medium mini-type grouting hole of building, damand harbour project.
