Description

Odex Drilling / Simultaneous Casing Drilling


ODEX is an excellent option when unconsolidated formations are too dense or cobbly for Auger Drilling. ODEX is a down-hole air hammer system that is designed to advance casing during drilling. Once a desired depth is reached they eccentric bit can be retrieved leaving the casing in place for sampling or installations.

Overburden Casing Drilling System DTH Bit is very popular in international water well and ore drilling field.

Features

Hardening treatment of the part's surface

with longer operating life and excellent anti - wear properties.

Structural optimization

Strengthen the structural strength, easy to operate

Superior performance

Stable and reliable performance, high drilling speed


Application Range:


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