摘　　要：粗格栅及进水泵房是我国目前对污水进行二级生化处理的重要构筑物,但其设施结构较深,对地基不均匀沉降十分敏感,沉井施工措施稍欠缺,就可能造成偏斜。文章简要介绍江南某软塑土地区如何进行降水、主体结构如何沉井施工的实践,为同类工程的设计和施工提供参考。Coarse grid and intluent pump station are the important building structure for secondary wastewater treatment in our country nowadays. As the two units are based on deep foundation, the least uneven settlement of foundation and deficiency in construction process will lead to the deviation of them. The article introduces engineering practice on how to make dewatering and open caisson construction of the main structure in a project above soft ground. And it can be referred in the design and construction of similar projects.
