NPD series Slurry Balance pipe-jacking machines：

1. The cutterhead with crushing function and high-pressure water nozzles can be selected according to the actual geological conditions.
2. The construction speed is fast as it can rely on the continuous delivery of soil through the slurry.
3. It has a wide applicable range of soil types and is particularly suitable for silt and sand layers. It especially performs outstandingly in strata with high underground water levels and large variations in soil quality.
4. The construction excavation face has strong stability, with minimal disturbance to the soil around the pipe being jacked during construction, resulting in extremely small ground settlement.
