Bridge building method and bridge
The invention relates to a bridge building method and a bridge. The bridge building method comprises the steps that a whole-span main beam and a bridge pier with a bent cap are prefabricated; road traffic is blocked, and the prefabricated whole-span main beam and the pier with the bent cap are moved and transported; the prefabricated whole-span main beam is moved to the position of a bridge site, the whole-span main beam is supported, and then the pier with the cover beam is moved to the position below the whole-span main beam; prefabricating and assembling bridge piers with cover beams and bearing platforms located at bridge sites are prefabricated and assembled; and the whole-span main beam is supported on the bent cap. For the whole-span main beam which is changed from orthogonality to skew, the pier-beam cooperation synchronous construction method is adopted, the long edge of the whole-span main beam is not hindered by the pier in the moving and advancing direction, and new construction of the bridge is completed smoothly. And meanwhile, the assembly construction speed can be increased, and the construction efficiency is improved. In addition, by the adoption of the bridge building method, traffic only needs to be closed temporarily in the process of moving and transporting the whole span of the main beam and the bridge piers, the traffic closing time is shortened, and the influence of bridge building construction on road traffic operation is reduced.
本发明涉及一种桥梁新建方法及桥梁。桥梁新建方法包括预制整跨主梁，及带有盖梁的桥墩；封闭道路交通，移运预制的整跨主梁和带有盖梁的桥墩；先将预制的整跨主梁移运至桥位的位置，支撑整跨主梁，再将带有盖梁的桥墩移运至整跨主梁的下方；预制拼装带有盖梁的桥墩和位于桥位的承台；将整跨主梁落架在盖梁上。对于正交转斜交的整跨主梁，采用上述“墩梁协同”同步施工的方法，整跨主梁的长边在移运前进方向不受桥墩的阻碍，保证桥梁新建施工顺利完成。同时，还能够加快装配化施工速度，提高施工效率。此外，采用该桥梁新建方法只需在移运整跨主梁及桥墩的过程中短暂封闭交通，缩短交通封闭的时间，减小桥梁新建施工对道路交通运营的影响。
