摘要
结合宜兴市丁蜀污水处理厂较大沉井结构施工实践,介绍了沉井施工技术工作流程和方法,采用管井降水技术确保施工,提出了分段下沉和边下沉边进行上部沉井结构制作的工艺,沉井下沉作业时,基于信息化施工,采用人工挖土和水冲法(干湿交替作业法)相结合的施工方法,可以节约工期、有效控制下沉速度,保证下沉垂直度,工程质量良好,对沉井施工是一个极其有效的施工方法。
The paper introduced work processes and methods of caisson construction with construction methods of the larger sewage caisson structure of Dingshu Sewage Treatment Plant in Yixing City.It wsed tube well precipitation,proposed the sub-sink and process of sink with the upper caisson fabrication,and the artificial excavation and hydraulic method combined with the caisson sinking operations based information construction.The method could save construction period,control sinking speed,ensure the vertical sinking and project quality,which is an extremely effective construction method.
