Bridge hollow slab dismantling method
The invention discloses a bridge hollow slab dismantling method. The method comprises the following steps that S1, an asphalt pavement layer in a bridge deck pavement layer is dismantled; s2, a concrete pavement layer in the bridge deck pavement layer is subjected to transverse and longitudinal joint cutting, so that two adjacent bridge hollow slabs are separated, and a hinge joint between two adjacent single hollow slabs in each bridge hollow slab is exposed; s3, drilling holes towards the corresponding hinge joints from the longitudinal kerfs of the concrete pavement layer by using a drilling tool to form pushing holes into which a jack can extend; s4, a jack extends into a pushing hole between the to-be-dismantled single hollow slab located on the outer side and the adjacent single hollow slab located on the inner side, and the jack is used for applying force to the to-be-dismantled single hollow slab so that the to-be-dismantled single hollow slab can be separated from the adjacent single hollow slab; and S5, the separated single hollow slabs are hoisted to set storage points one by one through hoisting equipment. The hollow slab can be quickly dismantled in a low-cost and environment-friendly mode.
本发明公开了一种桥梁空心板拆除方法，包括以下步骤：步骤S1：拆除桥面铺装层中的沥青铺装层；步骤S2：对桥面铺装层中的砼铺装层进行横向和纵向切缝，以将相邻两跨桥梁空心板进行分离及使各跨桥梁空心板中的各相邻两片单片空心板之间的铰缝露出；步骤S3：利用钻具自砼铺装层的各纵向切缝朝对应的铰缝钻孔，形成可供千斤顶伸入的顶推孔；步骤S4：将千斤顶伸入位于外侧的待拆除单片空心板和位于内侧且与其相邻的单片空心板之间的顶推孔中，利用千斤顶对此待拆除单片空心板施力而将此待拆除单片空心板和相邻单片空心板进行分离；步骤S5：利用吊装设备将分离出来的单片空心板一一吊装至设定存放点。其能够实现快速、低成本且绿色环保地拆除空心板。
