Bridge with continuous simply-supported bridge floor and reinforcing and construction method
The invention provides a bridge with a simple structure and a continuous bridge deck and a reinforcing and construction method. The bridge comprises a pier, a first precast beam, a second precast beam, an integration layer, an asphalt concrete layer and an ultra-high performance concrete layer. The first precast beam and the second precast beam are arranged on the pier. The gap between the first precast beam and the second precast beam is located in the corresponding area of the working face of the pier. The integration layer is located on the sides, away from the piers, of the first prefabricated beams and the second prefabricated beams. The asphalt concrete layer and the ultra-high performance concrete layer are located on the side, away from the pier, of the integration layer and cover the integration layer. Wherein the ultra-high performance concrete layer at least covers the area above the pier top of the pier. Asphalt concrete in the area above the pier top is replaced by ultra-high performance concrete (UHPC), the ultra-high tensile property and crack resistance of the UHPC are used for improving the crack resistance of a bridge deck continuous layer, rainwater on the bridge deck is prevented from permeating into an existing integrated layer, and therefore the appearance and durability of a bridge are improved.
本发明提供了一种结构简支桥面连续的桥梁、加固及施工方法。该桥梁，包括桥墩、第一预制梁、第二预制梁、整体化层、沥青混凝土层及超高性能混凝土层。第一预制梁及第二预制梁设置于桥墩上。第一预制梁及第二预制梁的间隙位于桥墩的工作面的对应区域内。整体化层位于第一预制梁及第二预制梁远离桥墩一侧。沥青混凝土层及超高性能混凝土层位于整体化层远离桥墩一侧，并覆盖整体化层。其中，超高性能混凝土层至少覆盖桥墩的墩顶上方区域。在墩顶上方区域内的沥青混凝土采用超高性能混凝土（UHPC）代替，利用UHPC超强的抗拉性能和抗裂能力提高桥面连续层的抗裂能力，并防止桥面雨水渗透进入现整体化层，从而提高桥梁外观和耐久性。
