Bridge deck structure and expressway maintenance construction process
The invention relates to a bridge deck structure and an expressway maintenance construction process, and the bridge deck structure comprises a steel beam top plate which is welded with studs; stud holes matched with the studs are reserved in the UHPC prefabricated slab, the UHPC prefabricated slab is laid above the steel beam top plate and is positioned with the studs through the stud holes, and slurry is filled between the UHPC prefabricated slab and the steel beam top plate; and the wearing layer is laid on the upper layer of the UHPC prefabricated slab. The construction period can be effectively shortened by adopting the UHPC prefabricated slab as the pavement lower layer, the steel beam top plate is connected with the UHPC prefabricated slab through the studs, so that the UHPC prefabricated slab and the steel beam top plate can be firmly bonded and cooperatively stressed, and the pavement layer problem caused by fixed-point starting and braking of a heavy-load vehicle can be effectively solved; the method has the advantages of high efficiency, convenience in construction, reliable quality, suitability for factory prefabrication and on-site rapid construction and the like, and has a wide application prospect in related rapid road maintenance and construction.
本发明涉及一种桥面结构及快速道路维修施工工艺，其包括：钢梁顶板，其焊接有栓钉；UHPC预制板，所述UHPC预制板上预留有与所述栓钉相匹配的栓钉孔洞，所述UHPC预制板铺设于所述钢梁顶板的上方，并通过所述栓钉孔洞与所述栓钉定位，所述UHPC预制板与所述钢梁顶板之间灌有浆料；磨耗层，其铺设于所述UHPC预制板的上层。采用UHPC预制板作为铺装下层可有效缩短施工工期，钢梁顶板通过栓钉与UHPC预制板连接，使得UHPC预制板与钢梁顶板可以粘结牢靠，协同受力，可以有效解决重载车定点启动、制动所造成的铺装层问题，具有高效、施工便捷、质量可靠、适宜工厂化预制及现场快速施工等优点，在相关道路快速维修及施工中具有广阔的应用前景。
