Sectional type quick dismantling and replacing method for anti-collision wall of bridge
The invention discloses a sectional type quick dismantling and replacing method for a bridge anti-collision wall. The sectional type quick dismantling and replacing method comprises the following steps that 1, an old anti-collision wall is divided into a plurality of old anti-collision wall sections; 2, all old anti-collision wall sections are lifted away through a crane; 3, an old anti-collision wall root left after the old anti-collision wall section is removed is broken and removed, and embedded steel bars, used for being connected with the main beam, of the old anti-collision wall in the old anti-collision wall root are reserved; 4, a new anti-collision wall section is hoisted in place at the position of the broken old anti-collision wall through a crane; and 5, pouring a UHPC material between the new anti-collision wall section and the main beam, so that the embedded steel bars and the overhanging anchoring steel bars of the new anti-collision wall section are anchored to form a force transmission system. The replacement speed of the bridge anti-collision wall can be increased, meanwhile, the influence of construction on the surrounding environment is reduced, and the component quality of the newly-built anti-collision wall is guaranteed.
本发明公开了用于桥梁防撞墙的节段式快速拆除更换方法，包括如下步骤：1、在旧防撞墙分割出多个旧防撞墙节段；2、采用吊机吊离所有旧防撞墙节段；3、破除旧防撞墙在被去除了旧防撞墙节段后留下的旧防撞墙根部，并保留旧防撞墙根部内旧防撞墙用于与主梁连接的预埋钢筋；4、采用吊机在完成破除的旧防撞墙的位置吊装就位新防撞墙节段；5、在新防撞墙节段和主梁之间浇筑UHPC材料，使预埋钢筋与新防撞墙节段的外伸锚固钢筋锚固成传力体系。本发明能够提高桥梁防撞墙的更换速度，同时减少施工对周边环境的影响，并保证新建防撞墙的构件质量。
