Construction method for cofferdam with bottomed steel hanging box suspended by steel casing of complex deepwater riverbed
The invention relates to a construction method of a complex deepwater riverbed steel casing suspended bottomed steel suspension box cofferdam, a steel casing supporting steel cofferdam bottom plate assembly system can realize preliminary load bearing of a bottom plate through a primary keel and a secondary keel, and meanwhile, factory prefabrication of a bottom plate unit can be realized by adopting a prefabrication and assembly module unit technology. And mounting grooves and second sealing rubber are arranged on the prefabricated assembly module units, so that the side formworks can be positioned, the sealing performance of the joints of the side formworks and the bottom plate can be improved, and water is prevented from permeating into the cofferdam in the cofferdam downward hoisting process. Meanwhile, the rapid bottom plate joint plugging device adopts a prefabricated assembly module unit technology, factory prefabrication of the bottom plate unit can be achieved, the hoisting efficiency and safety of the side formworks are high, and the sealing performance of the side formworks is remarkably improved due to the fact that sealants are arranged at the connecting joints of the side formworks. And in the sinking process of the cofferdam, water on the outer bottom surface of the cofferdam is discharged into a water storage space preset in the cofferdam through a second hose and a bottom plate conversion hole, so that the influence of water resistance at the bottom surface of the cofferdam on downward lifting of the cofferdam is reduced.
本发明涉及一种复杂深水河床钢护筒悬吊有底钢吊箱围堰的施工方法，钢护筒支撑钢围堰底板拼装体系通过主、次龙骨可实现对底板的初步承重，同时采用预制拼装模块单元技术，可实现底板单元的工厂化预制。预制拼装模块单元上设有安装槽和第二密封橡胶，可对侧模板进行定位与提高侧模板与底板连接处密封性，避免围堰下吊过程中水体渗入围堰内。同时，底板快速堵缝装置采用预制拼装模块单元技术，可实现底板单元的工厂化预制，且侧模板吊装效率及安全性高，且其连接缝隙处设置密封胶，显著提高侧模板的密封性。围堰下沉过程中，围堰外底面的水通过第二软管和底板转换孔排入围堰内预先设置的储水空间，以减小围堰底面处水阻力对围堰下吊的影响。
