The Comacchio GEO line drill rigs are designed as multipurpose units, able to meet the different requirements and needs related to geotechnical site investigation projects.
Goto JK Drilling to know more.
The GEO line includes a wide range of models installed on (steel or rubber) crawler tracks, ranging from lightweight and small footprint units ideally suited for small geotechnical site investigation and environmental drilling projects inside buildings or in areas of restricted space, heli-portable solutions, to heavy-duty machines with a weight class up to 22 tonnes. The flexible design of Comacchio GEO rigs and the use of a comprehensive choice of rotary equipment and on-board accessories ensures that each set-up incorporates the ability to perform multiple drilling types from the same rig. Comacchio GEO line rigs can adapt to virtually any rotary drilling application, as well as rotary percussion drilling techniques, in all geological formations. Moreover, our GEO rigs can be configured for Sonic drilling for ground investigations in challenging ground conditions. Typically, our geotechnical site investigation equipment is used to:
produce high quality core samples;
perform percussive sampling;
carry out in situ mechanical property testing (e.g. Standard Penetration Test – SPT or Direct Push Probing – DPP);
install borehole instrumentation for long-term monitoring of ground conditions;
perform deep wireline coring;
perform open hole drilling techniques, including solid or hollow stem augering.
A range of solutions can be offered to deal with operational limitations due to access, confined space, emission controls etc.
CWD600 Multi-functional track mounted water well drilling rig is a efficient,multi-function full hydraulic water well drilling rig.It is high efficiency because of having a larger torque of the turntable and is mainly used for water well in industry and agriculture, national defense building foundation, geological exploration, geothermic well and other foundation working, it is popular at home and abroad.
CWD600 crawler mounted drilling rig can drilling in all kinds formations by mud drilling in soft formation and air DTH hammer in rock drilling,DTH Hammer is applied in rock drilling, slag is discharged by air pressure and the offstage efficiency is ten times than traditional rotary drilling.
