Bridge deck pavement system and pavement method suitable for pedestrian steel overpass
The invention relates to the technical field of pedestrian steel overbridges, and provides a bridge deck pavement system and method suitable for a pedestrian steel overbridge, and the pavement system comprises a shear key structure which is used for being connected with the top surface of a steel bridge; and the UHPC pavement layer is paved on the top of the steel bridge, the thickness of the UHPC pavement layer is uniform, and the UHPC pavement layer covers the top surface of the shear key structure. According to the method, the durability of overbridge pavement can be improved, and the diseases such as pavement falling, swelling, cracking and water seepage can be reduced or avoided, so that the pavement system structure is firmer, the method can adapt to the stress requirement of a steel overbridge under crowd load, the ultrathin UHPC pavement matched with the actual stress requirement of the overbridge can also have good economical efficiency, and the method is suitable for popularization and application. And meanwhile, the UHPC combined pavement system of the overbridge improves the rigidity of the bridge deck of the steel overbridge, and the problem of local tremor of the steel overbridge is effectively solved.
本发明涉及人行钢天桥技术领域，提供一种适用于人行钢天桥的桥面铺装系统及铺装方法，铺装系统包括：剪力键结构，用于铺装与钢桥的顶面连接；UHPC铺装层，铺设于钢桥的顶部，UHPC铺装层的厚度均匀，且UHPC铺装层覆盖住剪力键结构的顶面。本发明能够提升天桥铺装的耐久性，减少或避免铺装脱落、鼓包、开裂、渗水等病害，以使铺装系统结构更加牢固，既能适应钢天桥在人群荷载下的受力需求，与天桥实际受力需求相匹配的超薄UHPC铺装也能具有较好的经济性，同时这种天桥的UHPC组合铺装体系提高了钢天桥桥面板的刚度，有效改善钢天桥局部震颤的问题。
