摘要
本文以既有车站新建旅客地道工程为背景,介绍旅客地道出入口施工中基坑上方铺设贝雷梁临时便桥的设计与施工。既可最大限度地减少对既有线干扰,减少对车站站台接发旅客列车影响,又能在贝雷梁桥下按明挖顺作法施工旅客地道出入口结构;既安全可靠的加快新建旅客地道的施工进度,又很好地解决站台接发旅客与基坑施工的立体交叉矛盾,为类似工程提供了参考,能广泛推广应用。
Based on the background of the new passenger tunnel project at the existing railway station, this paper introduces the design and construction of the temporary belay beam laying above the foundation pit in the entrance and exit construction of the passenger tunnel.It can not only minimize the interference to the existing railway lines, reduce the impact on passenger trains receiving and dispatching at stations, but also construct the entrance and exit structures of passengers under the Bailey bridge under the open excavation method; It not only accelerates the construction progress of the newly-built passenger tunnels in a safe and reliable manner, but also satisfies the threedimensional cross-contradictions between passengers receiving and receiving at the platform and the construction of the foundation pits. It provides a reference for similar projects and can be widely applied.
