Hollow slab bridge maintenance method and hollow slab bridge
The invention relates to the technical field of hollow slab bridges, in particular to a hollow slab bridge maintenance method which comprises the following steps: S1, detecting along a hollow slab bridge deck, marking and counting damaged hollow slabs, and dividing the damaged hollow slabs into structural damaged hollow slabs and non-structural damaged hollow slabs according to whether the damaged hollow slabs are structurally structured or not, measuring the size of the structural damaged hollow slab, and determining the size of the steel beam structural member for repairing according to the measured size; s2, milling and removing a bridge deck pavement layer and a concrete cast-in-place layer of the structure-damaged hollow slab, milling and removing the bridge deck pavement layer and the concrete cast-in-place layer to an anti-collision guardrail in the transverse bridge direction, then removing concrete structures in hinge joints on the two sides of the structure-damaged hollow slab, disassembling the structure-damaged hollow slab, arranging a steel beam structural part at a vacant site, forming a spacing joint between the steel beam structural part and a hollow slab beam on the side, and carrying out construction; the problems that according to an existing maintenance method, the hollow slab bridge cannot be subjected to different maintenance according to the damage condition, and maintenance operation is inconvenient can be effectively solved.
本发明涉及空心板桥梁技术领域，尤其为一种空心板桥梁维修方法，包括以下步骤：S1，沿空心板桥梁桥面进行检测，标记并统计损坏的空心板，将损坏的空心板根据是否发生结构性分成结构损坏空心板和非结构损坏空心板两类，测量结构损坏空心板的尺寸，并根据测量尺寸确定修复用的钢梁结构件尺寸；S2，铣除结构损坏空心板的桥面铺装层和混凝土现浇层，并沿横桥向铣除至防撞护栏处，再清除结构损坏空心板两侧铰缝处内的混凝土结构，将结构损坏空心板拆下，在空位处布置钢梁结构件，钢梁结构件与旁侧的空心板梁形成间隔缝，本发明可以有效解决现有的维修方法无法根据损伤情况对空心板桥梁进行不同维修，维修操作不方便的问题。
