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/pipe-jacking-machine-tunnel-boring-machinery-tbm-10114043

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.
