Discussion on Waterproofing Technology of the Entrance and Exit Floor Renovation of Shanghai Metro Station
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.
