Suspended and assembled segment heightened sinking double-wall steel cofferdam and construction method
The invention provides a suspension assembly segment heightening sinking double-wall steel cofferdam and a construction method. The construction method comprises the key steps of large-size underwater obstacle removal, in-situ assembly platform building, in-situ assembly, inner support installation, guide pulley limiting, system suspension, intelligent monitoring, heightening assisting, water injection sinking, bottom sealing concrete pouring and the like. The intelligent detection system is introduced to realize real-time monitoring, and the construction precision and safety are improved; the in-situ assembly technology and the large-size underwater obstacle breaking technology are applied to improve the efficiency and overcome geological problems; a guide pulley and a steel strand suspension system guarantee vertical lowering of the cofferdam, and loss is reduced; the structure stability and perpendicularity are ensured through the self-floating height-connecting limiting device; and accurate sinking is realized by a water injection technology. The method is suitable for a deepwater complex geological environment and has a wide application prospect.
本发明提供一种悬吊拼装节段接高沉放双壁钢围堰及施工方法，包括大体积水下障碍物清除、原位拼装平台搭建、原位拼装、内支撑安装、导向滑轮限位、悬吊系统、智能监测、接高辅助、注水下沉和封底混凝土浇筑等关键步骤。本发明引入智能检测系统实现实时监控，提升施工精度与安全；运用原位拼装技术与大体积水下障碍物破除技术提高效率并克服地质难题；导向滑轮与钢绞线悬吊系统保障围堰垂直下放，减少损耗；自浮接高限位装置确保结构稳定与垂直度；注水技术实现精确下沉。本发明适用于深水复杂地质环境，具有广泛应用前景。
