    NPD Series Slurry Balance Pipe Jacking Machine For Tunneling In Soft-Soil


    The NPD Series slurry balance 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.

    Feature and advantages of NPD1200 slurry balance pipe jacking machine​:


    According to the different ways of controlling the mud on the excavation surface, the NPD series pipe jacking machine can be divided into two types: direct control type and indirect control type (air pressure composite control type).


    a. The direct control type pipe jacking machine can control the working pressure of the mud water tank by adjusting the speed of the mud pump or adjusting the opening of the mud water control valve. This control method is simple and convenient, and the failure rate is low.


    b. The indirect control pipe jacking machine indirectly adjusts the working pressure of muddy water tank by changing the pressure of the air cushion tank. This control method has a sensitive response and high control accuracy.


    1. The automatic control air cushion can provide precise support for the tunnel face, so as to ensure the safety of tunnel driving to the greatest extent.

    2. Tunneling can also be carried out when the water pressure is above 15bar.

    3. Use mud as the main medium to balance the formation pressure on the excavation surface of the tunnel, and discharge the slag through the mud conveying system.

    4. NPD1200 slurry balance pipe jacking machine is suitable for tunnel construction with high water pressure and high ground settlement requirements.

    5. High driving efficiency, safe and reliable, with two balance modes of direct control and indirect control.

    6. The NPD1200 slurry balance pipe jacking machine with advanced and reliable cutter head design and mud circulation.
