摘　　要：上海地铁运营线网中,有为数不少的车站出入口缺少下行自动扶梯,根据相关部门要求,上海地铁已开展了一部分出入口的加装扶梯改造,并计划未来几年覆盖全网;加装扶梯过程中,有部分出入口需要局部开挖结构底板增设扶梯基坑,施工风险较大。以此类涉及出入口改造项目为例,介绍运营车站出入口底板改造中的防水关键技术,以期为今后同类型改造项目的防水设计提供借鉴。In the network of Shanghai Metro,there are a large number of station entrances and exits that lack escalators.According to the requirements of relevant departments,Shanghai Metro has carried out the renovation of some entrances and exits with escalators,and plans to cover the whole network in the next few years.In the process of installing the escalator,some entrances and exits need to excavate the structure floor to add the escalator foundation pit,and the construction risk is greater.Taking this kind of renovation project involving entrance and exit as an example,this paper introduces the key technology of waterproofing in the renovation of entrance and exit floor of operating station,in order to provide reference for the waterproofing design of similar renovation projects in the future.
