Pressurized Ring Beam for Tunnel Stability and Installing Method of Pressurized Ring Beam

摘要

invention TBM (Tunnel Boring Machine) and by a method using TBM tunnel construction to time, the circular according as the installation structure in the jibojae tunnel excavation, the concrete is pressed by using a concrete-filled cell to expand the cross-section is formed by a circular structure as jibojae charged therein, a circular structure is jibojae more close contact and pressed against the tunnel face and thereby reduce the amount of the Girder Girder design and at the same time enhance the ability to support a greater load will pass through the load to the tunnel face excavation by the load relocation according to a cross section of a circular structure by further jibojae the pressure cell By permanently fixing the expanded state, the tunnel with concrete-filled pressure cell in the enhanced ability to configure Zibo new constitution will be continued excavation of the round jibojae structure and the construction method. ;
