Novel cofferdam structure for underwater straining beam construction and construction method of novel cofferdam structure
The invention belongs to the technical field of bridge construction, and particularly relates to a novel cofferdam structure for underwater straining beam construction and a construction method thereof.The novel cofferdam structure comprises a plurality of pile foundation construction steel platforms, a cofferdam bottom end supporting frame, a straining beam bottom die, a steel formwork assembly, a hoisting system and a tensioning assembly; a cofferdam bottom end supporting frame is installed on each of the two adjacent supporting cross beams, a straining beam bottom die is installed between the two cofferdam bottom end supporting frames, the steel formwork assembly is arranged on the cofferdam bottom end supporting frames and the straining beam bottom die in a surrounding mode to form an overall cofferdam structure, and the tensioning assembly is installed on the steel formwork assembly. And hoisting systems are erected between the two foundation construction steel platforms. The construction method has the technical characteristics that a hoisting system descending mode is adopted, divers do not need to go into water to block internal gaps, sealing of the gaps around the cofferdam structure and the pile foundation steel casing is achieved by arranging the leaking stoppage plate, a large amount of underwater operation can be reduced, and the construction efficiency is greatly improved.
本发明属于桥梁施工技术领域，具体涉及一种水中系梁施工用的新型围堰结构及其施工方法，包括多个桩基施工钢平台、围堰底端支撑框架、系梁底模、钢模板组件、吊装系统和拉紧组件，桩基施工钢平台平行架设有支撑横梁，相邻两根支撑横梁均安装有一个围堰底端支撑框架，两个围堰底端支撑框架之间安装有系梁底模，且围堰底端支撑框架和系梁底模上围设有钢模板组件以形成一个围堰整体结构，拉紧组件安装在钢模板组件上，两个基施工钢平台之间均架设有吊装系统。本发明具有采用吊装系统下放方式，不用潜水员下水封堵内部的间隙，且设置堵漏板的方式实现围堰结构与桩基钢护筒周围空隙的封模，可以减少大量的水下作业，大大提高了施工效率的技术特点。
