ODS Technique
Overburden Drilling method
Roschen’s ODS technique is a confirmed two-part Eccentric Overburden Drilling program designed for the EPTTltaneous drilling and casing of holes, by means of unstable floor conditions.
Essential Attributes:
. Available for casing sizes from 114mm (4 one/2 quot) to 273mm (10 frac34 quot) diameter Basic two-part style for EPT transfer of vitality to Little bit confront
. Optimum drilling overall performance in unstable ground conditions
. The Eccentric Little bit can be easily and swiftly taken off for alternative or refurbishment
. quotopen and closed quot locking arrangement inside of the little bit holEPTTso absolutely nothing can prevent the Eccentric Bit from closing
. The ODS Bit has a positive pilot style which aids XiHu (West EPT) Dis.Hu (West EPT) Dis. the Eccentric Bit and generate a straighter hole

ODEX
EPT produces ODEX Eccentric Overburden Drilling Technique, commencing with the ODEX90 to ODEX445. This a few -piece program includes of pilot bit, reamer,XiHu (West EPT) Dis.Hu (West EPT) Dis. gadget. EPT ODEX overburden drilling programs are widely employed in a variety of purposes from effectively drilling and mining to rock anchoring and web site investigation.
Positive aspects:
– Quick removal of cuttings EPT penetration price, eEPTTly in resistant rock formation
– EPT soil and groundwater sampling throughout drilling
– Achievable to measure yield estimate at picked depth in the development
– Advantageous in unconsolidated formations with a high danger of caving
Software Selection:
It is suitable for drilling drinking water wells, geothermal wells, brief mirco EPTs, medium mini-variety grouting hole of developing, dam and harbour undertaking.
one. When drilling starts off, the reamer swings out and reams the pilot-gap wide enough for the casing tube to slide down driving the drill bit assembly.
two. When the required depth is attained, rotation is reversed cautiously, whereupon the reamer swings in, enabling the drill bit assembly to be pulled up by means of the casing.
3. Casing tubes that are to be still left in the drill hole ought to be sealed at the base of the hole by indicates of cement grout or some other sealing agent.
four. Drilling continues to the preferred depth in the bedrock using a conventional drilling.
