Red Sea Sui Chi tunnels to Suifenhe section of the rail tunnel Mudanjiang expansion and reconstruction project, the design of tunnel-type import and export are used hat oblique Portal to meet the aesthetic requirements. The New Austrian Tunnel construction methods, lining are made of composite lining.Ⅲ ~ Ⅴ grade wall rock songs are used with the tunnel invert lining structure, Entrance by Myeong excavation, to advance support and overall lining. Tunnel ventilation with forced ventilation. Drainage design to take "anti-, row, section, block combined with local conditions in a comprehensive" principle; in the water-rich location and there are strict requirements on the water environment of the lot, take the "block-based, limited emissions"Principle. In accordance need to set up an inclined shaft of the tunnel as an auxiliary tunnel. Tunnel equipped with fixed lighting, additional emergency lighting, special chamber set to a fixed lighting. The construction, excavation by blasting, over and under strict control digging, shotcrete initial support wet spray process and carry out scientific construction management.
Key words: composite lining; ventilation; lighting; smooth blasting
Red pool tunnel suijiang line shore section railroad tunnel to 2000, mudanjiang, this design engineering revamping/import and export all USES tunnels DongMen crosswise type hats, in order to achieve beautiful and requirements. This tunnel adopted new Austrian tunneling method method, lining structure adopts composite linings. Ⅲ ~ Ⅴ level rock tunnel adopts curved wall lining structure form with arch supine by Ming hole hole section, excavation, advanced supporting and overall lining. Tunnel ventilation using pressure into type ventilation. Drainage design take "anti, platoon, cut, plugging union, adjust measures to local conditions, the comprehensive management" principle; In the watery section of water environment and strict requirements on the location, take "mainly limited emission, blocking principle. According to need this tunnel set up a slope as auxiliary tunnel. Tunnel with fixed ?
