Product Detailed

Foundation piles construction in large diameter for grouting pile holes drilling of highrise building , po

I. General
GQ-15A Drill is a new type of product designed by our factory. The drill is in the aligned hydraulic feeding system, so it can drill in the ways by pressuring and dispressuring. It can even load and unload drill tools, raise and pull down drill frame quickly and conveniently thanks to the devices driven by cylinders.
The drill adopts direct and reverse circulation drilling technology, and drill in quaternary period gravel terrain and hard terrain. This type of drill can be mainly in application of foundation piles construction in large diameter for pile holes drilling of highrise building, bridge, etc. and it can be used for water well for industry and agricultural irrigation.
