ZJD2300/120 RCD Rig (Reverse Circulation Drilling Rig) for Large Diameter Bored Piling Works


ZJD series RCD rig is specifically used for foundation drilling of large diameter of bored pile(1.0-5.0m). This equipment is used for drilling a borehole through soft and hard rock layers for foundation construction.
Drill string with special drill bit is used for drilling in the borehole, and the sand-stone and mud are flushed out through the drill pipe rods by the pressure difference in the hole.


ZJD2300/120 full hydraulic drilling rig can be clamped in the pile casing and used for vertical pile and tilting pile drilling, This is an efficient, safe and environmentally solution for:

  • Large dia (about 2.3m)
  • Depth (more than 140m)
  • Hard rock (75Mpa ~ 250Mpa)
  • Bore piling in marine conditions, gulf area, port

Advantages and Features

1, High efficiency and energy saving, full hydraulic stepless speed change, reliable and stable transmission performance.
2, Large torque, large lifting force, especially suitable for complicated stratum such as gravel, hard rock etc.
3, The suspension tiltable power head and tiltable frame with compact and reasonable structure, easy to assembly and disassembly.
4, Large diameter drill pipe, using high-pressure gas lift seal device and advanced RCD method.
5, Optional additional weight to increase pressure in hole bottom, ensure the verticality of the hole.
6, Optional stabilizer to assist drilling, effectively control the verticality and hole diameter precision,

reduce drilling tool wear.
7, Simple operation, low maintenance cost, comfortable environment of operation room, optional installation of temperature adjusting device.
8. High cost efficiency. the overall drilling costs can actually be reduced by up to 40% when using RCD, safety and requires fewer man hours, requires less water than other method.
9. Easy to collect samples. Any depth of the sample will help to study and analysis of geological condition.
