Reverse Circulation Drilling (RCD)/ GPS-10B for Bored Pile Drilling
R.C.D Machine is large bored pile equipment of soil foundation. Our
model GPS-10B drilling rig is applied on large diameter
cast-in-situ piling with reinforced-concrete for high-rise
building, harbor, dam, bridge, and can also drill large diameter
hole of water well and engineering hole.The main models include GPS10,GPS15,GPS18 and GPS20, etc.
Main features
1,The rotary table is equipped with six speeds, remarkably
improving construction efficiency.
2,Rotary table drives drilling pipe through shifting rod, much more
convenient for operation, higher safety and greatly reducing labor
intensity.
3,Both main and auxiliary hoists adopt planetary gear structure,
easy for operation and more reliable.
4, Adopt round drill pipe, reducing the auxiliary operation time.
5, Equipped with gravel pump set (pump-suction reverse
circulation), can transfer to reverse circulation drilling if
needed, and can also matched with air-lift reverse circulation
drilling tools for deep hole drilling.
