Construction method for removing old bridge and newly building bridge without interrupting traffic
The invention discloses a construction method for removing an old bridge and newly building bridges without interrupting traffic. The construction method comprises the following steps that a first bridge and a second bridge are newly built on the two sides of an original old bridge correspondingly; two-way traffic on the old bridge is guided to the first bridge firstly, and then the old bridge is dismantled; bridge decks flush with the surface of the second bridge are installed on the two sides of the second bridge, so that bidirectional widening of the second bridge is completed; two-way traffic on the first bridge is guided to the widened second bridge, and the first bridge is closed; bridge decks flush with the surface of the first bridge are installed on the two sides of the first bridge, so that bidirectional widening of the first bridge is completed; and then the traffic flow in one direction is guided to the widened first bridge, and only the one-way traffic flow in the other direction is reserved on the second bridge. According to the method, the transformation mode of double-side bridge building and two-way widening is adopted, the defects of existing single-side widening and double-side widening are overcome, the defects existing after double-width bridges are widened are overcome, and the later maintenance cost is reduced.
本发明公开了一种不中断交通的旧桥拆除并新建桥梁的建造方法，包括以下步骤：在原有旧桥的两侧分别新建一座第一桥梁和第二桥梁；将旧桥上的双向交通均先引导至第一桥梁上，而后拆除旧桥；在第二桥梁的两侧安装与其表面平齐的桥面板，以完成第二桥梁的双向拓宽；将第一桥梁上的双向交通引导至拓宽后的第二桥梁上，封闭第一桥梁；在第一桥梁的两侧安装与其表面平齐的桥面板，以完成第一桥梁的双向拓宽；而后将其中一个方向的车流引导至拓宽后的第一桥梁上，第二桥梁上仅保留另一方向的单向车流。本发明方法采用双侧新建桥梁+双向拓宽的改造方式，避免现有单侧拓宽、双侧拓宽的弊端，并规避了双幅桥拼宽后存在的弊端，减少后期维修养护成本。
