Method for replacing height-adjustable support
The invention discloses a method for replacing a height-adjustable support. The concrete construction technology of the method comprises the following steps of: mounting a temporary support at a position close to the side surface of the support, and adjusting the temporary support to be tightly attached and fixed with an upper structure and a lower structure; lowering the height of the support, and unloading the load of the support; disassembling the support to be replaced, and installing a new support; and adjusting the support to the initial position, and detaching the temporary support. A synchronous jacking technology can be replaced, rapid replacement of a single support in the operation period is achieved, a bridge does not need to be jacked, the technical difficulty is small, the danger coefficient is low, the occupied area is small, the coordination workload is small, medium-broken bridge operation is not needed, and the cost is low.
本发明公开了一种高度可调节支座的更换方法,具体施工工艺包括以下步骤:在临近支座侧面位置处安装临时支撑,调节临时支撑使其与上部结构和下部结构密贴、固定;降低支座高度,将支座卸去载荷;拆除待更换支座,并安装新支座;调节支座至初始位置,拆除临时支撑。本发明可取代同步顶升技术,实现运营期单支座的快速更换,无需顶升桥梁,技术难度小,危险系数低,占地少,协调工作量小,无需中断桥上运营,成本低。
