Pipe Jacking Machine Easy, control ground surface, subside and may come true, to continuous unearthed, work, jack speed fast - details see: https://www.machineto.com/realtop-pipe-jacking-machine-tunnel-boring-machinery-tbm-10114039

First Thanks for your interest, Ms. Aileen Zhu is at your service now~

The whole system allows the construction of an open caisson with the minimal inner dimension 4m×6m.

Besides the high efficiency, it also has effect on the traffics on surface. Furthermore, it is good for the environment, and can lower the cost of the construction.

We could supply you pipe jacking machinery diameter from 400mm to 4000mm (round or square)
