1、温州市高教园区北入口4#桥防撞护栏施工方案一、工程概况:4#桥起点桩号K1+311.17,终点桩号K1+428.71。全长117.54米,桥型分为东、西幅成反“S”型。防撞护栏布置在东、西幅内侧位置,4#桥防撞护栏混凝土采用C30,防撞护栏采用定型钢模,一次浇筑成型。二、施工技术方案1、主要施工流程钢筋绑扎模板安装安装预埋件浇筑混凝混凝土养护拆模2、主要施工方法在施工桥梁防撞护栏之前,用水在其施工的表面冲洗干净,然后开始绑扎桥梁防撞护栏的钢筋。钢筋绑扎施工前,必须检查钢筋、焊条和预埋件的品种、规格和质量必须符合设计要求和现行有关钢筋、焊条的标准
2、规定。钢筋工序施工时绑扎一定要牢固,钢筋应平直,表面不应有裂纹,油污和片状老锈。桥梁防撞护栏的钢筋绑扎一定要整齐,规格、间距、保护层厚度一定要符合设计及规范要求。钢筋绑扎好以后,再放置预埋件,预埋件安装一定要准确,以利于以后下一道安装工序。以上工作施工完毕以后,通过班组和质检部门自检合格后,通知监理验收,监理验收合格后,方能进行模板安装工作。钢筋工序完成以后,进行模板工序的立模工作。防撞护栏的模板采用装配定型钢模板,模板的每节长度为1.feelfreetolistentotheirvoicesandhelpthemassessolveprobl
