YGL-180 Reverse Circulation Drilling Rig
Applications：
YGL-180RC is mounted on a crawler chassis,driven by full hydraulic system, power head type drilling rig, which is used to drill vertical or inclined hole, and also the drilling techniques way of the following:
Drill auger drill
Down-The-Hole hammer drill
Mud forward circle drill
ODEX tools(casing pipe following) drill with DTH hammer
Medium reverse circle dril
The drilling rig is able to resolve the difficulty of boring in the soft and loose cover ground condition, the screes and gravels area and also the fragmentation stratum according to different drilling techniques ways. Therefore, it is widely used in varieties of the boring work.
The drilling rig is mainly applied in RC drill,geothermal hole,anchor hole of deep basement foundation anchoring and reinforcement groundwork hole. Also, it is used in drilling in the drain hole and large tonnage prestressed anchoring hole of the geotechnical engineering such as the side slope of dam construction,railways,highways etc., and the anchoring hole of landslide preventing, pipe roof drill work,grouting reinforcement hole,mini foundation pile hole,water well and observation well.
