Products Description

LEANOMS Symmetrix/Symmetric overburden drilling systems

Symmetrix is a patented system comprised of an ingeniously simple concentric method of drilling through over- burden with casing. Symmetrix drills straight holes, in any type of ground conditions, at any angle and to depths beyond 100 meters.

The Symmetrix system

The three main components of the system are made up of:

A pilot bit that drills away the center part of the hole and guides the drill string. The pilot bit is attached to any common DTH hammer shank or top hammer rod thread.
A casing shoe welded to the casing pipe which is pulled down by the impact of the hammer and pilot bit.
A symmetrical ring bit that is locked onto the pilot bit drills the void for the casing to advance down the hole. There are three different types of ring bit and cas- ing shoe assemblies;
■A solitary ring bit with no connection to the casing shoe.
■A welding ring that holds the ring bit and casing shoe together.
■A factory assembled ring bit set with integrated ring bit and casing shoe.

Permanent or retrievable casings

Permanent or retrievable casings

Pile types in foundation drilling
Foundation piles are generally divided in two different types, end bearing piles and skin friction piles.

End bearing piles

Installing end bearing piles

1.Casing is installed until bedrock

2.Drill string is pulled out from the hole

3.Reinforcement element is installed and concrete poured into the hole

Skin friction piles

Installing skin friction piles
1.Casing is installe.
2.Drill string is pulled out from the hole
3.Reinforcement element is installed and concrete poured in
Finally the casing is pulled out with ring bit set

Common system requirements

Large pass through inner Diameter

System with large pass through inner diameter
1.Casing is installed until bedrock
2.Drill string is pulled out from the hole
3.Drilling of the well continues with a DTH bit, which passes through the ring bit

Systems with drill-through pilot bit

System with drill-through pilot bit
1.Casing is installed until surface of bedrock
2.Drill through pilot bit is unlocked from ring bit and after that pilot bit drills a rock socket Drill string is pulled out from the
hole
3.Reinforcement element is installed and concrete poured into the hole

Special system designs--Symmetrix features

Each Symmetrix system is made from high quality al- loy steel, and has been precision machined to produce a perfect bit body, heat treated to the required hardness, and fitted with durable tungsten carbide buttons.
