The invention provides a construction method of an assembly type open caisson method of a rotational flow well. The construction method is implemented through the following steps that S1, prefabricated sections of the side wall of the rotational flow well are spliced into a ring; S2, earthwork is excavated in the rotational flow well to the designed well bottom elevation; and S3, a bottom plate ofthe rotational flow well is constructed. By adopting the construction method, foundation pit supporting and formwork and scaffold erecting are avoided, and on-site pouring is omitted, so that the construction work amount and dangerous factors in construction are reduced, and the construction cost is saved; and meanwhile, the construction period is greatly shortened by adopting factory prefabricated section assembly type construction.
本发明提供了一种旋流井装配式沉井法施工方法，通过以下步骤来实施：S1，将旋流井侧壁预制段拼接成环；S2，旋流井内开挖土方至设计井底标高；S3，施工旋流井底板。采用本发明的施工方法，避免做基坑支护以及搭设模板和脚手架，省去现场浇筑，从而减少了施工工程量和施工中的危险因素，节约了施工成本，同时采用工厂预制段装配式施工大大缩短了施工工期。
