Beam body jacking method for high-speed railway bridge
The invention provides a beam body jacking method for a high-speed railway bridge. The beam body jacking method comprises the following steps: installing a temporary support between a pier and a beambody to support the beam body; reaming a sleeve hole in the padstone; installing a vertical jacking device for jacking the beam body; jacking the beam body to a preset height to generate a height difference between the support and the padstone; cushioning a steel plate between the support and the padstone to fill the height difference; and pouring the sleeve hole reamed by the padstone. The heightdifference is generated between the support and the cushion stone, and the steel plate is cushioned between the support and the cushion stone to fill the height difference so as to support the beam body through the steel plate; and the cushion steel plate can enable the beam body to be kept at the preset height, and the settlement problem of a bridge is solved on the premise that a support anchoring system does not need to be transformed.
本发明提供了一种用于高速铁路桥梁的梁体顶升方法，包括以下步骤：在桥墩与梁体之间安装临时支座以支撑梁体；对垫石上的套筒孔进行扩孔；安装顶升梁体的竖向顶升器；顶升梁体至预设高度，支座与垫石之间产生高度差；在支座与垫石之间垫设钢板以填充所述高度差；浇注垫石扩孔后的套筒孔。该梁体顶升方法支座与垫石之间产生高度差，在支座与垫石之间垫设钢板填充上述高度差以利用钢板支撑梁体；垫设钢板能够使梁体保持在预设高度，在无需对支座锚固体系进行改造的前提下，解决桥梁的沉降问题。
