地铁车站盖挖法支撑系统施工技术

Construction Technology of Subway Station Supporting System with Cover Digging Method

佛山至东莞城际铁路番禺大道站采用局部盖挖顺做法施工,为保证地面正常通行,采用了贝雷桁架作为主梁的临时路面系统。施工实践表明,贝雷桁架作为主梁具有足够的承载能力和良好的安全稳定性,可作为一种新型的路面盖板支撑系统在地下车站等工程施工中推广应用。

The Panyu Avenue Station of Foshan to Dongguan Intercity Railw-ay is constructed by local cover digging. In order to ensure the normal passage of the ground, the Belee truss is used as the temporary pavement system of the main girder. Construction practice shows that the Beier truss as the main beam has enough bearing capacity and good safety and stability, and can be used as a new type of road cover support system in underground construction and other construction applications.
