本文结合上海杨树浦电厂取水隧道盾构封门实例,通过室内试验以及强度验算,确定了作为轻质混凝土装配式封门的材料配比。经实践检验,这种材料可用作深埋的水工和交通隧道盾构进出工作井封门的优选材料。
In this paper, taking the example of shield door of water intake tunnel in Shanghai Yangshupu Power Plant, the ratio of materials used as light-weight concrete assembly-sealed doors was determined through indoor tests and strength checking. This material has been proven to be used as a preferred material for deep-buried hydraulic and tunneling tunnels in and out of service wells.
