Slurry Balance Pipe Jacking Machine
Inquire NowDescription
CRCHI’s slurry balance pipe jacking machine represents cutting-edge technology ideal for micro tunneling. This versatile machine excels in a wide range of ground conditions, including silt, sand, rock, and high water pressure geologies. It is extensively utilized in various construction projects such as urban cable tunnels, water supply and drainage tunnels, gas pipelines, underground passages, and utility tunnels.
The machine operates through a rotating cutterhead equipped with cutting tools that excavate material from the tunnel face. The excavated material is mixed with mud in the excavation chamber to create slurry, which is then transported via a slurry pipe to a separation plant above ground. A jacking device, located at the launch shaft or intermediate jacking stations within the shield, pushes the shield and specially designed pipes through the ground.
Basic components of the standard slurry balance pipe jacking machine include:
- Cutterhead
- Main drive
- Shield
- Hydraulic system
- Slurry feeding pipeline
- Slurry pump
- Slurry discharge pipeline
- Backup system
- Thrust device
