Integrated prefabricated pump station open caisson construction method and reinforcing mold
The invention relates to an integrated prefabricated pump station open caisson construction method and a reinforcing mold. The integrated prefabricated pump station open caisson construction method comprises the steps of open caisson excavation, in-well mud clearing and conveying, concrete bottom sealing and pump station hoisting and debugging which are conducted in sequence, wherein the step of open caisson excavation comprises the sequential steps of excavating a well mouth, specifically, excavating downwards by unit depth from the ground in a construction area; reinforcing the well mouth, specifically, installing the reinforcing mold at the well mouth, enabling the lower ends of an inner cylinder and an outer cylinder to be attached to the well bottom, enabling the upper ends of the inner cylinder and the outer cylinder to be higher than the ground, and pouring concrete slurry into a formed space; conducting open caisson deep excavation, specifically, excavating downwards continuously by unit depth in the construction area; conducting well wall reinforcement, specifically, forming a reinforcing ring after concrete in the formed space is solidified, enabling the reinforcing ring to move downwards till the lower end of the reinforcing ring is attached to the well bottom, and pouring the concrete slurry into the formed spaced again; and repeating the steps of open caisson deep excavation and well wall reinforcement till excavation of the preset depth is completed. Downward excavation and concrete solidification are conducted synchronously, and the construction efficiency is improved.
本申请涉及一种一体化预制泵站沉井施工方法及加固模具，施工方法包括依次进行的沉井开挖、井内泥浆清运、混凝土封底、泵站吊装及调试；步骤沉井开挖包括依次进行的：井口开挖，在施工区自地面向下挖掘单位深度；井口加固，在井口处安装加固模具，并使得内筒及外筒的下端贴合井底，且内筒及外筒的上端高于地面；再向成型空间内浇注混凝土浆料；沉井深挖，在施工区继续向下挖掘单位深度；井壁加固，成型空间中的混凝土凝固后形成加固环，加固环向下移动，直至加固环的下端贴合井底；并再次向成型空间内浇注混凝土浆料；重复步骤沉井深挖及井壁加固，直至完成预定深度的挖掘。向下挖掘与混凝土凝固同步进行，提高施工效率。
