天桥在黄土地区逆作施工方法应用

Application of Inverse Construction Method of Overpass in Loess Area

在黄土地区,天桥作为二级公路上跨国道或高速公路,主要连接村与村间连通要道,深挖路堑天桥在公路中较为常见,工法也较成熟,但工期长,支架搭设技术难度大,施工安全风险高。国道310洛三界至三门峡西段南移新建工程王沟天桥通过优化传统施工工艺流程,采取逆作工艺的技术措施,有效解决施工难题,降低安全风险,保证施工进度和质量。

In the loess region,the overpass as a cross-country road or highway on the secondary highway,the main connection between the village and the village connecting the main road,deep cut overpass in the highway is more common,the construction method is more mature,but the construction period is long,the technical difficulty of bracket construction,construction safety risk is high.By the optimization of the traditional construction process and adopting the technical measures of the reverse construction process,the construction problem is effectively solved,the safety risk is reduced and the construction progress and quality are guaranteed.
