日前,由中铁十四局承建的跨汉宜高铁特大桥顺利推进,该桥采用重载铁路混凝土箱梁顶推跨越既有高铁线施工在全国尚属首次,为蒙华铁路全线建成通车创造了条件。中国铁建十四局蒙华铁路项目经理刘志波介绍说,跨汉宜高铁特大桥全长6 584 m,是蒙华铁路湖北段重点控制性工程,跨汉宜高铁顶推邻近既有线作业项目工艺复杂,有效施工时间短,安全风险高。施工中,对施工平台、支架进行绝缘处理,将触电危险降至最低;在顶推过程中,技术人员随时对
Recently, the construction of the cross-Han-Yi Express Rail Bridge under the auspices of China Railway 14 has been successfully carried out. The construction of the bridge using the heavy-load railway concrete box girder over the existing high-speed railway is the first time in the whole country and created for the opening and closing of the entire Mongolia- condition. Liu Zhibo, project manager of Mongolia-Huayu Railway of China Railway Construction 14 Bureau said that the total length of the trans-Han High Speed Rail Bridge is 6 584 m, which is the key controlled project of the Mongolia-Huayu Railway in Hubei Province. The cross-Han high-speed railway is pushing the adjacent existing line operations Complex technology, effective construction time is short, high security risk. During the construction, the construction platform and the support shall be insulated to minimize the risk of electric shock. During the pushing process, the technicians may at any time
