近年来城市交通变得越来越拥挤,为了缓解交通压力,政府部门在主要交通路口修建了许多地下过街通道,改变人流、车流相互干扰的混乱局面。结合实例,本文介绍了地下通道的防水设计,主要包括结构主体、暗挖地下通道和特殊部位的防水设计和施工工艺。 In recent years, urban traffic has become more and more crowded. To ease traffic pressure, government departments have built many underground passageways at major traffic intersections to change the chaotic situation in which people and traffic flow interfere with each other. Combined with examples, this article describes the waterproof design of underground channels, mainly including the structure of the main body, undercutting underground channels and special parts of the waterproof design and construction process.
