Rapid sinking method for open caisson of rotational flow sedimentation tank
The invention relates to a rapid sinking method for an open caisson of a rotational flow sedimentation tank. The construction period and the construction cost are saved by reducing the sinking elevation of a first section of the open caisson and optimizing the sectional manufacturing and sinking sequence; meanwhile, the manufacturing and sinking quality is effectively controlled by adopting a padframe technology, an observation technology and a refined excavation method; the sinking depth of a first layer is greater than 5m, so that the actual sinking height can be reduced; meanwhile, the contact area of a soil body and the side wall is reduced, so that the frictional resistance is greatly reduced, and sinking is facilitated; the next section of the open caisson can be manufactured by utilizing the concrete curing time through one-time sinking of sectional manufacturing; and meanwhile, the problem of repeatedly erecting and disassembling a scaffold during sectional manufacturing and fractional sinking is avoided, so that the construction period and the construction cost are saved.
本发明涉及一种旋流沉淀池沉井快速下沉方法，通过降低首节沉井起沉标高，优化分节制作和下沉顺序节约工期和施工成本，同时采用垫架技术、观测技术及细化的挖土方法，有效控制制作和下沉质量；首层下沉深度大于5m，可以减少实际下沉高度。同时减少土体已侧壁接触面积，大大减小摩阻力，有利于下沉；分节制作一次下沉，可以利用混凝土养护时间进行下一节井壁制作。同时避免分节制作分次下沉时反复搭设和拆除脚手架的问题，节约工期和施工成本。
