ODEX is an abbreviation of Overburden Drilling EXentric and is a generic term used to describe percussively drilled and cased piles. Typically used in challenging ground conditions such as soils with cobbles, boulders and rock layers, and can be used to pile through mine workings, and broken or laminated rock. THE PROCESS

Odex drilling and or Symmetrix drilling is often used in situations where the ground formation is relatively soft or less consolidated, such as in loose soils, clay, and sand or boulders. It is also commonly used in areas where there is a risk of collapsing boreholes or unstable formations. Odex and Symmetrix drilling methods both include using.

A drilling casing is a type of drilling tool that enables you to case and drill simultaneously. It can be used with rotary percussion drilling where the impact of the hammer drives the casing down the wellbore. Installing casing, while drilling, minimizes the risk of holes collapsing and enables projects to be completed faster and more efficiently.

The ODEX system is very economic when it comes to shallow and short holes. At the start, the ODEX eccentring reaming wing is in a close position, and when the system starts drilling at the end of the casing, the reamer swings out in the drilling position and thus enlargers the hole for the casing to advance. With its eccentric reaming wing.

ODEX is an adaptation of the air-operated down-the-hole hammer. It uses a swing-out eccentric bit to ream the bottom of the casing. Cuttings blow up through the drive sub and casing annulus to a swivel conducting them to a sample collector or onto the ground. High penetration rate, especially in resistant rock formation (e.g. basalt)

ODEX equipment enables you to drill and case deep holes simultaneously in all types of formation, even those with large boulders. Casing diameters from 114mm (ODEX 90) to 273 mm (ODEX 240) can be used - 90 and 240 in the ODEX code stands for pilot outer diameter.

For unconsolidated overburden, the ODEX 3-method offers a way to install a casing down to the bedrock while drilling and to proceed drilling in the hard formation with normal DTH-equipment. If the overburden is too thick, or if instable rock is found at considerable depth, the DTH with pneumatic flushing of the cuttings can not be used.

In some loose and unstable rock formations, problems such as hole collapse and burial often occur during drilling. How to avoid this series of problems? After several years of on-site practice and research, Tianhe Drilling Tools has found that concentric drilling tools have the widest applicability to formations. In addition to dealing with eccentricity and the formation conditions targeted by.

Rock Anchors & ODEX. With our proven rock drilling techniques, piles can be installed into solid rock, or in voided ground such as heavily faulted rock, coal or other workings, and natural solution features. In these circumstances, our flexible drilling rigs are capable of drilling vertically and at any angle, so small and medium diameter piles.
ODEX
It allows the drilling with the down the hole hammer while going down a casing simultaneously. Two methods are available : the casing system by rotation called SATURN and the casing system by impulse of the hammer on the casing shoe of the casing called commonly ODEX or TUBEX. Some examples of applications of the overburden drilling system :
