Large-size special-shaped open caisson foundation construction method
The invention relates to a large-size special-shaped open caisson foundation construction method. The large-size special-shaped open caisson foundation construction method comprises the steps that foundation pit surveying and setting out are conducted, a site is leveled, an open caisson cushion layer is manufactured, and blade foot manufacturing is conducted; then a first open caisson section is prefabricated, an inner side scaffold and an outer side scaffold are erected on the inner side and the outer side of the well wall correspondingly, a formwork is mounted, and concrete is poured; afterthe first open caisson section reaches the design strength, in-well soil taking sinking is conducted; then a second open caisson section is prefabricated, an outer side scaffold is erected on the outer side of the well wall, an operation platform is erected at the top of the first open caisson section, and an inner side scaffold is erected on the operation platform; and the formwork is mounted, concrete is poured, after the second open caisson section is completed, in-well soil taking sinking is conducted, manufacturing sinking of the next open caisson section is conducted according to a manufacturing method of the second open caisson section, and finally open caisson bottom sealing is conducted. According to the open caisson construction method, the scaffold erecting, material using and erecting time can be saved.
本发明涉及一种大体积异形沉井基础施工工法，包括基坑测量放样、平整场地、制作沉井垫层并进行刃脚制作；然后预制第一节沉井，在井壁内外两侧分别搭设内侧脚手架和外侧脚手架，安装模板，浇注砼，待第一节沉井达到设计强度后，进行井内取土下沉，然后预制第二节沉井，在井壁外侧搭设外侧脚手架，在第一节沉井顶部搭设作业平台，在作业平台上搭设内侧脚手架，安装模板，浇注砼，待第二节沉井完成后井内取土下沉，按照第二节沉井的制作方法进行下一节沉井的制作下沉，最后进行沉井封底；本发明的沉井施工工法能够节省脚手架的搭设、用材、搭设时间。
