Product Description

NPD series of Slurry balance pipe jacking machine are most suitable for condition of high underground water pressure and various soil strata, commonly used for pipe diameter ranges from Φ800 to Φ4000 . The slurry system maintains the stability of the soil surrounding the pipe, enabling effective control soil settlement. It can also perform continuous unearthed action and the speed of pushing forward is fast.

Slurry shield pipe jacking machine has two types according to their different design in different application: Disc-wheel and Cone-wheel. each type can be manufactured in different size and configuration.
Slurry shield pipe jacking machine is capable of running for single long shaft length (up to 200m) without interjack shell.
