简介:摘要本文以尼日尔二桥下部结构施工为例,对比了不同栈桥修筑方案的优缺点,介绍了一般河流水中桩基与系梁施工工艺和技术方法等,重点阐述了水中桩基及系梁施工的技术要点,为今后类似工程的施工提供一些借鉴与参考。
简介:摘要:中铁隧道局集团承建的跨石长铁路特大桥YDK29+815~+840处跨越石长铁路,铁路与线路夹角为25.78°,采用2跨32m简支梁跨越。根据新建线路与既有石长铁路的位置临近关系,33~35号桥墩桥面系施工采用限速(≤45km/h)及搭设防电棚的防护方式进行施工,具有施工成本投入大、搭设及拆除天窗点多、对既有铁路行车安全隐患较大的缺点,通过现场踏勘研究,并与既有铁路设备管理单位的充分沟通及论证,在施工时采取了简支T梁“兜底”的防护措施,此防护措施不仅成本投入少、实施方便、快速,更是大大降低了对既有铁路行车的安全隐患,并且加快了工程建设进度,为今后类似工程提供了可供借鉴的工程实例。
