前 言
为进一步规范全省交通基础设施建设和管理行为，全面提升建设管理水平，按照交通工作实现"标准化、规范化、集约化、人本化"管理的目标要求，适应在山东省内不具备钢箱梁运输与架设条件的河流、山区以及跨线桥等环境下架设钢箱梁，山东省交通运输厅提出并主持编制了本规程。
本规程内容包括了钢箱梁顶推施工工艺流程及主要环节的施工技术要求。对提高并推广我国钢箱梁顶推施工技术，及时指导工程施工实践，规范施工方法，保证施工质量，将起到行业技术指导作用。 目录 1 总则........................................................................................................4 2 术语........................................................................................................4 3 施工准备................................................................................................6 3.1 施工调查........................................................................................6 3.2 专项施工方案................................................................................6 3.3 施工测量........................................................................................8 4 临时结构................................................................................................8 4.1 一般规定........................................................................................8 4.2 顶推平台........................................................................................9 4.3 临时墩..........................................................................................10 4.4 导梁.............................................................................................. 11 5 顶推装置.............................................................................................. 11 5.1 一般规定...................................................................................... 11 5.2 滑动装置...................................................................................... 11 5.3 导向装置......................................................................................12 5.4 支承系统......................................................................................13 5.5 顶推动力与控制系统..................................................................15 6 结构设计与计算..................................................................................16 6.1 一般规定......................................................................................16 6.2 结构计算......................................................................................16 7 顶推施工..............................................................................................18 7.1 一般规定......................................................................................18 7.2 临时结构的施工..........................................................................19 7.3 钢箱梁拼装及顶推......................................................................19 7.4 落梁..............................................................................................20 7.5 临时结构的拆除..........................................................................21 8 施工监控..............................................................................................21 本规程用词用语使用说明......................................................................23 附件..........................................................................................................24 1 总则......................................................................................................25 2 术语......................................................................................................25 3 施工准备..............................................................................................25 4 临时结构..............................................................................................26 5 顶推装置..............................................................................................28 6 结构设计与计算..................................................................................31 7 顶推施工..............................................................................................32 8 施工监控..............................................................................................34 附 工程实例..........................................................................................36
