1800mm Slurry Balance Pipe Jacking Machine For Tunnel Construction

Device positioning:

Safe Tunneling Technology in Heterogeneous Ground

Geological condition:

Soft soils, heterogeneous formations (sand, gravel, high permeability and high water pressure)

The NPD series pipe jacking machine is mainly suitable for the geological conditions with high groundwater pressure and high soil permeability coefficient. The excavated slag is pumped out of the tunnel in the form of mud through the mud pump, so it has the characteristics of high working efficiency and clean working environment.

Main Technical Specification:
