以苏州市轨交2号线为例,介绍了起减振作用的钢弹簧浮置板钢筋笼的预制及其道床快速施工。通过钢筋笼加工预制、吊装、运输及道床混凝土快速输送、浇筑工艺的革新,大大地压缩了钢弹簧浮置板道床的施工工期,节省了人力和物力,取得了一定的社会和经济效益。 Taking Suzhou Rail Transit Line 2 as an example, the prefabricated steel spring floating cage reinforcement cage and rapid ballast bed construction are introduced. Through the steel cage processing prefabrication, hoisting, transportation and rapid transfer of concrete ballast bed, pouring process innovation, greatly reducing the construction period of steel spring floating slab bed, saving manpower and material resources, and achieved some social and economic benefits.
