Prestressed floating bridge temporary bridge and construction method thereof
The invention provides a prestressed floating bridge temporary bridge and a construction method thereof, and relates to the technical field of construction temporary bridges. The prestressed floating bridge temporary bridge comprises a floating bridge body and floating bridge abutments, and further comprises a prestressed steel beam and tensioning pedestals. The floating bridge body comprises a plurality of steel frame cross beams which are sequentially hinged end to end, a plurality of floating boxes are arranged at the bottoms of the steel frame cross beams, the floating bridge abutments arranged on the two banks respectively are hinged to the two ends of the floating bridge body respectively, the two tensioning pedestals are arranged on the two banks respectively, the middles of the prestressed steel beams are located below the floating boxes, and the middle of the prestressed steel beam is located below the floating boxes. The two ends of the prestressed steel beam are connected with the two tensioning pedestals correspondingly. By the adoption of the scheme, the arch type construction temporary bridge replacing a cable hoisting system can be provided, construction of a steel truss arch bridge is converted into a split ring dividing mode, the construction difficulty is lowered, the engineering cost is saved, and the construction risk is reduced.
本发明提供了一种预应力浮桥便桥及其施工方法，涉及施工便桥技术领域，包括浮桥本体和浮桥桥台，还包括预应力钢束和张拉台座；所述浮桥本体包括首尾依次铰接的多根钢架横梁，所述钢架横梁底部设有多个浮箱，分设于两岸的浮桥桥台分别和浮桥本体两端铰接，所述张拉台座为两个，两个所述张拉台座分设于两岸，所述预应力钢束中部位于多个浮箱下方，所述预应力钢束两端分别和两个所述张拉台座连接；采用本方案，能提供一种替代缆索吊装系统施工拱式施工便桥，将钢桁拱桥的施工转变为分部分环的方式形成，降低了施工难度，节省工程造价，减少施工风险。
