Novel two-way curved arch bridge deck broadening and reinforcing method
The invention discloses a novel two-way curved arch bridge deck broadening and reinforcing method, which comprises the following steps of dismantling a bridge deck on an original two-way curved arch bridge, then cleaning and removing arch filler on the original two-way curved arch bridge, and dismantling an arch side wall on the original two-way curved arch bridge, planting steel bars between archwaves and arch ribs of an original two-way curved arch bridge, arranging newly-built reinforced concrete arch upper side walls on the two sides of the top face of the original two-way curved arch bridge respectively, and meanwhile when the newly-built reinforced concrete arch upper side walls are constructed, arranging pre-buried overhanging profile steel on the side walls, away from the center of the original two-way curved arch bridge, of the newly-built reinforced concrete arch upper side walls, and pouring bubble lightweight concrete into a cavity between the upper side walls of the newly-built reinforced concrete arch for filling. A large amount of repeated consumption of natural resources and equipment resources caused by demolition and reconstruction can be avoided, the bearing performance of the bridge can be remarkably improved, and meanwhile the method has the advantages of being convenient to construct, large in bridge deck broadening proportion, capable of greatly improving the arch rib bearing capacity and the like.
本发明公开了一种新的双曲拱桥桥面扩宽加固方法，拆除原来的双曲拱桥上的桥面板，然后清理刨除原来的双曲拱桥上的拱上填料，以及拆除原来的双曲拱桥上的拱上侧墙；在原来的双曲拱桥的拱波、拱肋间进行植筋；在原来的双曲拱桥的顶面两侧上分别新建钢筋混凝拱上侧墙，同时新建钢筋混凝拱上侧墙在施工时，新建钢筋混凝拱上侧墙远离原来的双曲拱桥中心的侧壁上设置有预埋悬挑型钢；新建钢筋混凝拱上侧墙之间的空腔内浇筑气泡轻质混凝土进行填充；本发明可以避免拆除重建带来的自然资源、设备资源的大量重复耗用，能够显著增加桥梁的承载性能，同时具备便于施工、桥面扩宽比例大、拱肋承载能力大幅提高等优点。
