Beam body jacking and deviation rectifying method for high-speed railway bridge
The invention provides a beam body jacking and deviation rectifying method for a high-speed railway bridge. The beam body jacking and deviation rectifying method comprises the following steps: installing a temporary support between a pier and a beam body to support the beam body; reaming a sleeve hole in a padstone; installing a vertical jacking device for jacking the beam body and a transverse pushing device for transversely moving the beam body; jacking and transversely moving the beam body to a preset position to generate a height difference between the support and the padstone; cushioninga steel plate between the support and the padstone so as to fill the height difference; and pouring the sleeve hole reamed by the padstone. According to the beam body jacking and deviation rectifyingmethod, the height difference 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 tosupport the beam body through the steel plate; and the longitudinal position of the beam body can be raised and kept through the cushioning steel plate, and the problem of bridge settlement is solvedon the premise that a support anchoring system does not need to be modified.
本发明提供了一种用于高速铁路桥梁的梁体顶升及纠偏方法，包括以下步骤：在桥墩与梁体之间安装临时支座以支撑所述梁体；对垫石上的套筒孔进行扩孔；安装顶升所述梁体的竖向顶升器和横移所述梁体的横向顶推器；顶升并横移所述梁体至预设位置，支座与所述垫石之间产生高度差；在所述支座与所述垫石之间垫设钢板以填充所述高度差；浇注所述垫石扩孔后的套筒孔。该梁体顶升及纠偏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的纵向位置升高并保持，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。
