Bridge widening method
The bridge widening method comprises the following steps that a first supporting frame is erected between a first bridge and a second bridge, a second supporting frame is erected on the side, away from the second bridge, of the first bridge, and a third supporting frame is erected on the side, away from the first bridge, of the second bridge; the first steel box girder is hoisted to the top of the first supporting frame, the second steel box girder is hoisted to the top of the second supporting frame, the third steel box girder is hoisted to the top of the third supporting frame, and the first steel box girder, the first bridge, the second steel box girder, the second bridge and the third steel box girder are sequentially arranged; a plurality of supporting piles are formed at the bottom of the first steel box girder, the bottom of the second steel box girder and the bottom of the third steel box girder in a pouring mode; and the first supporting frame, the second supporting frame and the third supporting frame are dismantled. According to the technical scheme, two or more existing bridges are combined and widened.
本发明公开一种桥梁拓宽方法，包括以下步骤：在第一桥梁和第二桥梁之间搭设第一支撑架，在第一桥梁远离第二桥梁的一侧搭设第二支撑架，在第二桥梁远离第一桥梁的一侧搭设第三支撑架；将第一钢箱梁吊装至第一支撑架的顶部，将第二钢箱梁吊装至第二支撑架的顶部，将第三钢箱梁吊装至第三支撑架的顶部，使第一钢箱梁、第一桥梁、第二钢箱梁、第二桥梁和第三钢箱梁依次设置；在第一钢箱梁的底部、第二钢箱梁的底部和第三钢箱梁的底部分别浇筑形成若干支撑桩柱；拆除第一支撑架、第二支撑架和第三支撑架。本发明的技术方案对两个或以上的既有桥梁进行合并和拓宽。
