Transformation operation structure of underwater single-column pier bridge and pier top transformation method
The invention discloses a reconstruction operation structure of an underwater single-column pier bridge and a pier top reconstruction method, and relates to the field of bridge maintenance and reinforcement engineering.The reconstruction operation structure comprises a simple buoyancy tank floating on the water surface and used for temporarily surrounding and fixing a single-column pier, and the simple buoyancy tank comprises two half buoyancy tanks which are symmetrically arranged; the steel cover beam comprises two symmetrically-arranged steel cover half beams, and the steel cover beam is used for movably surrounding the middle of the single-column pier before being lifted to the pier top and is further used for being fixed to the pier top after being lifted to the pier top; each half buoyancy tank is used for transporting and supporting one steel cover half beam; the lifting device comprises a lifting hanger and a plurality of electric hoists, and the lifting hanger is used for fixing the top end face of the single-column pier; and two ends of each electric hoist are respectively used for fixing the lifting hanger and the steel cover beam. According to the transformation operation structure and the pier top transformation method, under the premise of not interrupting bridge floor traffic and not filling soil to build a road, anti-overturning transformation of the single-column pier in water is completed.
本申请公开了一种水中独柱墩桥梁的改造作业结构及墩顶改造方法，涉及桥梁维修加固工程领域，包含：浮于水面且用于临时环抱固定于独柱墩的简易浮箱，其包含两个对称设置的半部浮箱；钢盖梁，其包含两个对称设置的钢盖半梁，所述钢盖梁用于在提吊至墩顶前活动环抱于独柱墩中部，还用于在提吊至墩顶后固定于墩顶；每个半部浮箱用于运输和支撑一个钢盖半梁；提吊装置，其包含提升吊架和若干电动葫芦，所述提升吊架用于固定独柱墩顶端面；每个电动葫芦的两端分别用于固定提升吊架和钢盖梁。本申请的改造作业结构及墩顶改造方法，在不中断桥面交通、不填土筑路的前提下，完成水中独柱墩抗倾覆改造。
