某主跨为4×100m预应力混凝土简支T梁桥,主墩基础采用直径2.2m的钻孔灌注桩,设计深度为25m,采用回转钻进施工法钻孔。施工单位严格按照设计文件和相关施工技术规范的要求进行施工,为了保证工程质量、工程进度,工程安全和控制工程成本,项目经理部分别组成了工程质量控制小组、工程进度控制小组、工程安全控制小组和工程成本控制小组。
工程施工过程中,各控制小组的部分工作如下。
工程质量控制小组设置了桥梁上部结构施工中的质量控制点是:
(1)预拱度的控制;
(2)拱肋拱轴线的控制;
(3)主缆架设线型控制;
(4)支座预埋件的位置控制;
(5)伸缩缝安装质量控制。
工程质量进度控制小组根据现场实际情况,编制了本工程施工组织设计。
工程安全控制小组提出了如下安全技术要求:
(1)高处作业操作平台的临边要设置高度为0.8m的防护栏杆。
(2)遇有七级以上大风、大浪应停止水上作业。
(3)拆除工程应自上而下进行,先拆除承重部分,后拆除非承重部分。
