Pushing construction dual-purpose pre-stress through bailey steel trestle and construction method of pushing construction dual-purpose pre-stress through bailey steel trestle
The invention belongs to the technical field of bridge construction, and particularly relates to a pushing construction dual-purpose prestress through bailey steel trestle and a construction method thereof. The Bailey steel trestle comprises two Bailey beam bodies arranged in parallel and a plurality of bridge deck distribution beams, a plurality of light bridge decks are arranged above the bridge deck distribution beams, the two ends of each Bailey beam body are provided with a prestress steel strand anchoring device and a Bailey beam end reinforcing structure respectively, and a triangular prestress tensioning assembly is arranged in the middle of each Bailey beam body. A pulley is arranged at the lower end of the triangular prestress tensioning assembly, the lower end of the pulley is connected with a prestress steel strand, and the two ends of the prestress steel strand are connected with the prestress steel strand anchoring devices respectively. By means of the design of the movable triangular prestress tensioning assemblies and the prestress steel strands, the problems that an existing beret steel trestle is poor in stress, poor in bearing capacity and troublesome in temporary reinforcement in a large-span structure are solved, the construction cost is saved, and the safety of the structure is improved.
本发明属于桥梁建设施工技术领域，特别涉及一种顶推施工双用预应力下承式贝雷钢栈桥及其施工方法。该贝雷钢栈桥包括两个相互平行设置的贝雷梁主体、多个桥面分配梁，桥面分配梁上方设有多个轻型桥面板，贝雷梁主体两端分别设有预应力钢绞线锚固器和贝雷梁端部加强构造，贝雷梁主体中间设有三角形预应力张拉组件，三角形预应力张拉组件下端设有滑轮，滑轮下端连接有预应力钢绞线，预应力钢绞线两端分别与预应力钢绞线锚固器相连接。本发明通过可活动的三角形预应力张拉组件以及预应力钢绞线的设计，解决了现有贝雷钢栈桥在大跨度结构中受力较差，承载能力较弱，临时加强较麻烦的问题，节约了施工成本，增大了结构的安全性。
