UHPC simply supported truss trestle and construction method thereof
The invention belongs to the technical field of construction of bridge large temporary facilities and emergency rush pass bridges, and particularly discloses a UHPC simply-supported truss trestle and a construction method thereof.The UHPC simply-supported truss trestle comprises a prefabricated UHPC upper chord, a prefabricated UHPC lower chord, a prefabricated UHPC vertical web member, a prefabricated UHPC inclined web member and a prefabricated UHPC bridge deck slab; fine steel wire meshes are arranged in the truss rod pieces; high-strength bolt hole sleeves are pre-buried in bolt holes of all UHPC components; stainless steel plates wrap angles. The components are connected through high-strength bolts according to a prefabricated assembly mode to form UHPC single trusses, and the multiple UHPC trusses and the UHPC bridge deck slabs are assembled to form the trestle. The UHPC material is adopted to prefabricate the truss members and the bridge deck slabs, the steel consumption can be greatly reduced, the construction cost of the trestle is reduced, the operation noise of the trestle is weakened, the whole is broken up into parts, and construction and replacement are convenient.
本发明属于桥梁大临设施及应急抢通桥梁的建造技术领域，尤其公开了一种UHPC简支桁架栈桥及其建造方法，包括预制UHPC上弦杆、下弦杆、竖向腹杆及斜向腹杆，预制UHPC桥面板；桁架杆件中配置细钢丝网；UHPC各构件螺栓孔预埋高强度栓孔套；不锈钢板包角。按照预制装配方式使用高强螺栓将构件连接形成UHPC单片桁架，多片UHPC桁架与UHPC桥面板组拼形成栈桥。本发明采用UHPC材料预制桁架构件和桥面板，可大幅减少用钢量降低栈桥建造成本，减弱栈桥运行噪音，化整为零，施工及更换方便。
