Specifications:

Pipe roof method is an advanced supporting structure for shallow underground excavation in underground structure engineering. Its essence is buried in arc arch lining implicit quasi excavation of the underground tunnel or structural engineering, pre drilled and thick wall steel pipe installation high inertia, temporary shoring, prevent soil collapse and surface subsidence, excavation and support to ensure the follow-up process safety operation.

Pipe roof support method is a newly developed technology for tunnel excavation in soft rock. Pipe roof method was first used as an auxiliary method of tunnel construction, through the loose belt, belt, soft ground breaking in soft rock tunnel, inflow of water, sand play an important role. Because the embedded piperoof roof and side wall support. To lay a solid foundation for the follow-up of the tunnel excavation, and the construction speed, high safety, short construction period. The construction method is considered to be the most effective and reasonable solution of roof collapse in tunnel construction.
