Anti-seismic reinforcement construction method for inverted-T-shaped bent cap frame pier
The invention relates to an anti-seismic reinforcement construction method for an inverted-T-shaped bent cap frame pier. The anti-seismic reinforcement construction method comprises the following steps that S1, an inverted-T-shaped bent cap is rigidly connected with an end diaphragm plate of a main beam on one side or two sides of the inverted-T-shaped bent cap; s2, temporary supporting and jacking devices are arranged on the peripheries of the pier columns of the frame pier, then the joints of the pier columns and the inverted-T-shaped cover beams are cut off, and the inverted-T-shaped cover beams are jacked; s3, the truncated working face is cleaned, the pier top is reinforced through high-strength concrete, and then a seismic mitigation and isolation support is placed; and S4, the inverted-T-shaped cover beam falls back, the seismic mitigation and isolation support is fixedly connected with the inverted-T-shaped cover beam and the pier column, and the temporary supporting and jacking device is removed. Compared with the prior art, the construction method does not change the original total gap width of the beam end of the existing bridge, meanwhile, reduction of structural response under an earthquake is facilitated, and the overall construction method is simple, easy to operate, high in economical efficiency and convenient to apply and popularize.
本发明涉及一种倒T形盖梁框架墩的抗震加固施工方法，包括以下步骤：S1：将倒T形盖梁与其一侧或两侧主梁的端横隔板进行刚接；S2：在框架墩的各墩柱周围设置临时支撑顶升装置，随后将墩柱与倒T形盖梁的交接处截断，并顶升倒T形盖梁；S3：清理截断工作面并用高强混凝土加固墩顶，随后放置减隔震支座；S4：将倒T形盖梁回落，将减隔震支座与倒T形盖梁和墩柱固接，撤去临时支撑顶升装置。与现有技术相比，本发明的施工方法不改变既有桥梁梁端原有的总缝隙宽度，同时有利于减小地震下的结构响应，整体施工方法简单，易于操作，经济性强，便于推广和应用。
