新型叠合装配式地铁车站结构施工与防水技术探析

Analysis of Construction and Waterproofing Technologies for New Composite Prefabricated Metro Station Structures

新型叠合装配式施工技术是2024年由无锡地铁5号线率先适用, 其与装配整体式车站的最大区别在于, 其预制构件更为细致, 分作梁、板、墙等小型预制件, 以“搭积木”的方式实施地铁车站。深圳地铁19号线为全国采用叠合装配式车站的第二条地铁线路, 相关防水技术相对不够成熟。文章结合了无锡地铁站的成功案例, 结合深圳当地的地质情况和项目实际, 通过对叠合装配式车站的施工工艺和防水做法开展研究, 总结了明挖装配式地铁站的相关施工要点, 为后续的叠合装配式建设提供参考依据。 

The new composite prefabricated construction technology was first applied on Wuxi Metro Line 5 in 2024. The biggest difference from monolithic prefabricated stations lies in its more detailed prefabricated components, which are divided into small prefabricated parts such as beams, slabs, and walls, allowing the metro station to be constructed in a “building block” manner. Shenzhen Metro Line 19 is the second metro line in China to adopt a composite prefabricated station, and its waterproofing technology is relatively immature. Combining the successful case of Wuxi Metro Station with the local geological conditions and actual project situation in Shenzhen, this paper studies the construction technology and waterproofing methods of composite prefabricated stations, summarizes the key construction points of metro stations, and provides a reference for subsequent composite prefabricated construction.
