Bridge pier underwater straining beam lifting, prefabricating and downward hanging installation system and construction method
The invention provides a pier underwater straining beam lifting, prefabricating and downward hanging installation system and a construction method. The construction method comprises the steps that a pile foundation is constructed; mounting a vertical component of the prefabricated platform; mounting the upper structure of the prefabricated platform; constructing a straining beam prefabricated part; cofferdam plates are installed; hoisting the precast beam and the cofferdam; constructing bottom sealing concrete and waterproofing; water in the cofferdam is pumped out, and the interior of the cofferdam is kept dry; constructing cast-in-place straining beam joints; and removing the cofferdam and the template. The middle section of the straining beam is lifted and prefabricated, the nodes at the two ends of the straining beam are cast in situ in water, straining beam prefabrication and cast-in-situ are organically combined, and the straining beam construction quality and efficiency are guaranteed; the cofferdam plate, the straining beam, the straining beam formwork and the joint formwork are put down as an integral structure, in-water cast-in-place of joint cast-in-place at the two ends of the straining beam is achieved, the integrated operation level is improved, the cofferdam construction difficulty is lowered, the cofferdam mounting and dismounting time is shortened, and a reliable and safe construction operation environment can be provided.
本发明提供一种桥墩水中系梁抬高预制下吊安装体系及施工方法，包括：步施工桩基；安装预制平台竖向构件；安装预制平台上部结构；施工系梁预制部分；安装围堰板；吊装预制梁与围堰；施工封底混凝土与防水；围堰内排水：将围堰内的水抽出，保持围堰内干燥；施工现浇系梁节点；拆除围堰与模板。本发明通系梁的中间节段抬高预制、系梁两端节点水中现浇，将系梁预制与现浇有机结合，保证了系梁施工质量与效率；通过围堰板、系梁及系梁模板、节点模板作为整体结构下放，实现系梁两端节点现浇的水中现浇，提高了集成化作业水平，降低围堰施工难度，又减少围堰安装与拆卸时间，并能提供可靠、安全施工作业环境。
