Bridge anti-seismic support device and jacking replacement construction method thereof
The invention discloses a bridge anti-seismic support device and a jacking replacement construction method thereof.The anti-seismic support device comprises an anti-seismic support, a wedge block, a perforated steel sleeve and a self-leveling concrete heightening block, the anti-seismic support comprises a support lower sealing layer steel plate, a support upper sealing layer steel plate and a support body, the perforated steel sleeve is provided with a support hole and a pier column hole, and the self-leveling concrete heightening block is arranged in the support hole; the perforated steel sleeve is sleeved on a lower structure pier column, a containing space is formed between the perforated steel sleeve and a support cushion stone located at the top of the pier column, and the self-leveling concrete heightening block is of a structure formed by solidifying after the containing space is filled with concrete in a cast-in-place mode. A support lower sealing layer steel plate of the anti-seismic support is placed in a support hole, the anti-seismic support is further provided with a support upper pre-buried steel plate and a support upper anchor rod, and the wedge block is of a structure formed by cast-in-place concrete with the support upper pre-buried steel plate as a pouring formwork. The invention further discloses a construction method for jacking and replacing the bridge anti-seismic support device.
本发明公开了一种桥梁抗震支座装置及其顶升更换的施工方法，该抗震支座装置包括抗震支座、楔形块、开孔钢套筒和自流平混凝土加高块，抗震支座包括支座下封层钢板、支座上封层钢板以及支座主体，开孔钢套筒开设有支座孔和墩柱孔，所述开孔钢套筒套装下部结构墩柱，开孔钢套筒与位于墩柱顶部的支座垫石之间形成容置空间，所述自流平混凝土加高块为混凝土现浇充满所述容置空间后凝固形成的结构；所述抗震支座的支座下封层钢板安放在支座孔中，抗震支座还具有支座上预埋钢板和支座上锚杆，所述楔形块为以所述支座上预埋钢板为浇筑模板现浇混凝土形成的结构。本发明同时公开了该桥梁抗震支座装置顶升更换的施工方法。
