Partial pressure deviation rectifying method for damping shock insulation rubber support after cast-in-place beam bridge forming
The invention belongs to a partial pressure deviation rectifying method for a damping shock insulation rubber support after cast-in-place box girder bridge forming. The partial pressure deviation rectifying method comprises the following steps: firstly, preparing a multi-directional jacking translation device, a leveling seat, a shockproof partial pressure column, a temporary supporting block and a stiffening suspender for the partial pressure deviation rectifying method, and preparing accessories such as a hoop, a longitudinal beam, a cross beam, a lower fixing steel plate and an upper fixing steel plate which need to be replaced, a shock insulation rubber support and a fastening bolt; the method comprises the steps of building a construction working platform, arranging the multi-directional jacking and translating device, correcting the deviation of the shock insulation rubber support, arranging the shock-proof partial pressure column, preliminarily falling back a box girder, pre-deviating the support, falling back the box girder in place and the like. Deviation of the cast-in-place box girder and the shock insulation rubber support can be effectively rectified and reset, meanwhile, the vertical rigidity and the vertical bearing capacity of the shock insulation rubber are improved under the condition that the shock insulation function of the shock insulation rubber is kept, and the good using effect is achieved.
本发明属于一种现浇箱梁成桥后阻尼隔震橡胶支座的分压纠偏方法，首先制备用于分压纠偏方法的多向顶升平移装置、调平座、防震分压柱、临时支撑块、加劲吊杆，备好抱箍、纵梁、横梁、需更换的下、上固定钢板、隔震橡胶支座和紧固螺栓等辅件。方法包括搭设施工工作平台、设置多向顶升平移装置、对隔震橡胶支座的偏移纠正、防震分压柱的设置、初步回落箱梁、支座预偏、回落箱梁到位等步骤。本发明能有效对现浇箱梁和隔震橡胶支座偏位进行纠偏复位，同时在保持隔震橡胶隔震功能状态下增加其竖向刚度和竖向承载力，有良好的使用效果。
