What is Pipe Roofing Method?
Pipe Roofing Method is a method where a row of steel pipes are installed to form a roof as a support system for underground space below it. This method stabilizes the ground to minimize settlement and ground movement. This method has been widely applied for tunnel excavation with shallow earth cover. It is also applied for construction of multi-purpose space, as well as countermeasure against slope collapse, uneven earth pressure, and ground collapse, etc.

Unclemole Pipe Roofing Method

We use Unclemoles, our slurry-type tunnel boring machines, to form pipe roofs. Unclemoles make it possible to form longer pipe roofs under different conditions (e.g. deeper earth cover).
