TRI-MACH DTH MULTI-USE RING BIT SYSTEM (CASING ADVANCEMENT)

In some geotechnical conditions and project requirements, the Multi-Use casing advancement system becomes the most economical choice. Tri-Mach Multi-Use system is designed for projects, where casing is retracted after reaching the required drilling depth.

Most common uses for Multi-Use / Retractable Casing Advancement System:

Pre-drilling, for example to soften the soil for later sheet pile installation
Casing drilling to required depth. Concreting and retracting the steel casing before concrete is hardened.
Installing certain elements, such as concrete elements with the help of a temporary drilled casing

FAQ: DTH-Drill Bits for Casing Drilling

Can you explain different terminology for DTH Drill Bits?

DTH Drill Bit is a term that is generally used for all drilling bits in DTH (Down-The-Hole). They could include for example:

DTH-Button Bit / DTH-Rock Bit = DTH Drill Bit designed to drill a rock hole without casing.
DTH-Pilot Bit = DTH-Drill Bit that is designed to drill casings / DTH-Piles. Normally used together with Ring Bits.
DTH-Wing Bit = DTH-Drill Bit that is used to drill casings without the Ring Bit.
DTH-Hole Opener = DTH Drill Bit that is used to enlarge existing rock hole diameters
DTH Multi-Use Casing Advancement System = System, that is designed for retracted casings. In other words, a single Ring Bit is used for drilling multiple times with the same casing.

What does DTH-Piling / DTH-Drilled Piles mean?

DTH-Drilled Piles are steel casings that have been drilled using the Down-The-Hole hammer (DTH). Piles are normally drilled through soil layers and into the bedrock. After drilling, casings can be concreted. In Multi-Use Casing System, the casing can be retracted and re-drilled again for another location.

When should I use the Multi-Use Casing Advancement System?

Multi-Use Casing Drilling System is used, when the same casing and ring bit are drilled multiple times.
Such conditions might include for example pre-drilling to soften and break rocks in the soil, or that the driller wants to retract the casing after drilling.
With the Multi-Use Casing Advancement System, it is possible to drill the casing with the DTH-method to required depth, reinforce&conrete the casing, and retract the casing right after concreting.
It is also used to install certain foundation elements in tough soils. Firstly, casing is DTH-drilled into required depth. Secondly, the designed element is installed to the bottom of the casing. Lastly, casing and the Multi-Use Ring Bit are retracted from the ground, leaving the element into designed depth.

In our project, we have piles with really challenging geotechnical conditions. Can you produce a Ring Bit that works even in these tough conditions?

Yes. We design project-specific custom models for tough conditions. Lately, this has been really popular with great results!
