Construction method for dismantling bridge concrete pavement layer
The invention discloses a bridge concrete pavement layer dismantling construction method, which belongs to the technical field of bridge maintenance, and comprises the following steps: firstly, marking grid lines on the surface of a to-be-dismantled concrete pavement layer of a bridge; secondly, the concrete pavement layer is cut along the grid line, and the concrete pavement layer is divided into independent concrete pavement layer blocks; then, a working face is selected, and concrete pavement layer blocks within the range of the working face are crushed and cleaned; thirdly, the concrete pavement layer blocks adjacent to the working face are entirely dismantled, and the range of the working face is expanded; and finally, dismantling the blocks one by one along the working face until all the bridge concrete pavement layer blocks on the bridge floor are dismantled. The concrete pavement layer is demolished mainly through static force, repeated action on a bridge body is not needed, damage to an original bridge structure is reduced, and high demolishing efficiency is achieved.
本发明公开一种桥梁混凝土铺装层拆除施工方法，属于桥梁养护技术领域，首先，在桥梁的待拆除混凝土铺装层表面标记网格线；其次，沿网格线切割混凝土铺装层，将混凝土铺装层分割为独立的混凝土块铺装层块；然后，选取工作面，将工作面范围内的混凝土铺装层块破碎并清理；接着，将与工作面相邻的混凝土铺装层块整拆除，扩大工作面范围；最后，沿工作面逐块拆除，直至拆除桥面的全部桥梁混凝土铺装层块。本发明主要通过静力拆除混凝土铺装层，无需对桥梁梁体反复作用，减小对桥梁原有结构的损伤，具有较高的拆除效率。
