因墩柱高度和地形条件限制 ,盖梁不能采用落地支架的施工方法 ,通过在墩顶预埋工字钢牛腿 ,设计安装吊架解决了盖梁模板的支承与吊装贝雷桁架 2个难题 ,同时混凝土浇注顺序的安排增加了桁架的安全储备 ,预拱度的设置确保了盖梁外形达到设计规定 ,因此该施工技术解决了高墩盖梁的施工难题 Due to the height of pier and the limitation of terrain conditions, the construction method of the floor girder can not be adopted for the girder girder. Through the prefabricated I-beam cowholes on the pier top, two problems of supporting and lifting the Beilun truss are solved by designing and installing the hanger , While the arrangement of concrete pouring sequence increases the safety reserve of the truss. The pre-camber setting ensures that the profile of the capping girder meets the design requirements. Therefore, the construction technique solves the construction problems of the capping girder with high pier
