Updating construction method of elevated box girder anti-collision wall
The invention provides a renewal construction method for an elevated box girder anti-collision wall, and relates to the technical field of viaduct construction, the renewal construction method comprises the following steps: dismantling an old wall: dismantling a main body part of the old anti-collision wall, and retaining a part, connected with a prestressed anchorage device of a box girder, on the old anti-collision wall; reinforcing steel bars are embedded for reinforcement, wherein connecting steel bars are embedded into the box girder; mounting and pouring are conducted, specifically, the prefabricated anti-collision wall is mounted, joints are formed between the prefabricated anti-collision wall and the box girder and between the prefabricated anti-collision wall and the part, connected with the prestressed anchorage device, of the old anti-collision wall, the connecting steel bars are arranged in the joints, and the joints are poured. The anti-collision wall has the effect that the new anti-collision wall and the old anti-collision wall can be rapidly replaced.
本申请提供了一种高架箱梁防撞墙的更新施工方法，涉及高架桥施工技术领域，其包括如下步骤：旧墙拆除：将旧防撞墙的主体部分进行拆除，并保留所述旧防撞墙上与箱梁的预应力锚具相连接的部分；植筋加固：在所述箱梁上植入连接钢筋；安装浇筑：安装预制防撞墙，在所述预制防撞墙与所述箱梁之间以及所述预制防撞墙与所述旧防撞墙上与预应力锚具相连接的部分之间形成接缝，且所述连接钢筋设于所述接缝内，并对所述接缝进行浇筑。本申请具有能够实现新旧防撞墙的快速更换的效果。
