Underwater open caisson segmental prefabrication synchronous sinking construction control method
The invention discloses an underwater open caisson segmental prefabrication synchronous sinking construction control method. The method comprises the steps that a construction support and a platform are erected, and a jack set is arranged on the construction support and the platform; synchronous pressurization control is conducted on the jack set; synchronous lifting control is conducted on the first section of concrete; synchronous sinking control is conducted on the first section of concrete; synchronously sinking the open caisson section by section and monitoring suspender stress in real time; and cleaning the construction site. According to the underwater open caisson segmental prefabrication synchronous sinking construction control method, synchronous accurate control is achieved, and the situations that the well wall is stressed unevenly, concrete cracks due to over-limit deformation, and safety and quality accidents are caused by over-limit deviation in the sinking process are avoided.
一种水下沉井分节预制同步下沉施工控制方法，所述方法包括步骤：搭设施工支架与平台并在其上设置千斤顶组；对所述千斤顶组进行同步加压控制；对首节混凝土进行同步提升控制；对首节混凝土进行同步下沉控制；逐节同步下沉沉井并实时监测吊杆应力；清理施工现场。本申请提供的一种水下沉井分节预制同步下沉施工控制方法实现了同步性精确控制，避免了井壁不均匀受力、超限变形混凝土开裂以及下沉过程出现超限偏位导致安全质量事故等情况的出现。
