Product Description

Earth pressure pipe jacking machine are suitable for all kinds of soil condition from soft to weathered sandstone. It can keep working well even when the soil depth down to machine shell is 1.0 times of pipe diameter. By applying proper grouting (injecting bentonite), surrounding soil structure improved, stability of cutter disc maintained and also ground subsidence is minimized. 

Earth pressure balance (EPB) pipe jacking machine is widely used for those projects who needs large diameter pipes and longer shaft jacking distance.

EPB machine brings a lot of benefits to customer: easy excavation and spoil transportation, simple and safe operation, long-life of machine running.
