移动式防护平台在跨既有线连续梁施工中的应用

摘要

以杭甬客专钱江铁路新桥南引桥连续梁跨越既有沪昆铁路施工为例,为解决沪昆线运输繁忙对铁路正常运营造成的影响,利用挂篮底模设置移动式防护平台与挂篮同步走行,从而确保了铁路运输及桥梁施工的安全。%Taking Nanyin bridge continuous beam of Hang-Yong passenger special railway line crossing existing Hu-Kun railway construction as an example,in order to solve the impact of Hu-Kun busy railway line upon normal railway operation,the paper puts forward synchronous orbit of hanging bottom-model setting movable protection platform and hanging basket.As a result,it ensures the security of railway transportation and bridge construction.
