Urban tunneling is one kind of TBM projects. When we mention the TBM, Tunnel Boring Machine, one must think of some in-city constructions like the subway, cross-mountain tunnel and etc. Exactly correct! In history of TBM, the tunnel diameter can range from as small as I meter by micro-TBM, to as large as 19.25 meters.

In TBM projects, there is special requirement that the surface of the working ground is better not disturbed or damaged. In this condition, the operator must pay enough attention to keep the soil pressures during and after construction of the tunnels. And also, pre-planning is vital to these projects, existing pipelines, and existing infrastructures must be taken into consideration.
