Construction method of prefabricated arch structure channel bridge
The invention provides a construction method of a prefabricated arch structure channel bridge. The construction method comprises the following steps of construction of a lower structure, production of prefabricated arch pieces, maintenance and transportation. Prefabricated arch pieces are installed; pouring an arch back wet joint; pouring wet joints of the arch feet; laying a waterproof layer; building a retaining wall and synchronously backfilling earthwork; construction of a hat stone and an anti-dazzle screen; and greening work. The method has the advantages of improving the construction efficiency, shortening the construction period, standardizing prefabrication production, ensuring the bridge forming quality and the like.
本发明提供了一种预制拱结构通道桥的施工方法,包括以下步骤:下部结构施工,预制拱片生产、养护运输;预制拱片安装;拱背湿接缝浇筑;拱脚湿接头浇筑;铺设防水层;搭建挡土墙并同步回填土方;帽石与防眩屏的构建以及绿化工作。本发明具有提高施工效率、缩短施工工期、标准化预制生产、保证成桥质量等优点。
