METHOD FOR SUPPORTING OF TUNNEL CROWN AND STABILIZING OF TUNNEL FACE BY CONTROLLING GROUTING DIRECTION, SUPPORT AND VACUUM DRAIN THROUGH STEEL PIPE |
摘要 |
PURPOSE: A method for draining water in vacuum using a steel pipe and stabilizing a tunnel face by controlling grouting direction is provided to improve waterproof performance and reduce subsurface water flowing into a turner face. CONSTITUTION: A method for draining water in vacuum using a steel pipe and stabilizing a tunnel face by controlling grouting direction comprises following steps. Steel pipes(10) are arranged in the shape of arch within a ceiling ground which is adjacent to an excavation side of the tunnel face according to the curve shape of the tunnel. The inside of the steel pipe installed is made in a vacuum condition and underground water is absorbed and drained. Grout material is injected into the steel pipe and an arch shaped cut-off structure is formed.
