Pipe Jacking Machine (TBM), trechless laying pipes, underground,, Easy control on ground surface,, continuous jack, speed fast - details see: https://www.machineto.com/d2500mm-pipe-jacking-machine-tunnel-boring-machinery-tbm-10114040

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.
