增加应力释放孔的胀管式管道更新施工工法内容介绍br增加应力释放孔的胀管式管道更新施工工法格式br/工法内容简述：针对传统的胀管法容易引起地下土整体位移胀管过程产生较大的胀破力会引起地面（路面）隆胀对周围的管线、设施等造成破坏,施工过程须大面积的拆迁配合等缺点我司组织技术研究小组进行专门研究对传统胀管法进行技术性创新改进：在旧管道和可能受破的结构（路面、管线、管井等）之间设置应力释放孔应力释放孔的位置和大小需根据管周土体特征（土质、密度、含水量、埋深等）和需保护设施的特性综合考虑后经计算和通过试验段确定。br/目 录一、工法申报表·········································3二、工法文本···········································131.前言………………………………………………………………………152.工法特点…………………………………………………………………173.适用范围…………………………………………………………………184.工艺原理…………………………………………………………………195.工艺流程及施工要点……………………………………………………206.设备与材料………………………………………………………………317.质量控制…………………………………………………………………328.安全措施…………………………………………………………………339.环境措施…………………………………………………………………3410.效益分析 ………………………………………………………………3511.应用实例 ………………………………………………………………36三、企业级工法批准文件·····································43四、关键技术鉴定证书·······································45五、工法应用证明、经济效益证明、项目研究合作协议···········55六、科技查新报告···········································64七、工法实际施工照片·······································71img src=http://f.99jianzhu.com/v1/tfs/T14RVTB7CT1RCvBVdK.png
