Construction system and construction method of steel truss bridge
The invention relates to a construction system of a steel truss bridge and a construction method thereof, and belongs to the technical field of steel truss bridge construction. A construction system of a steel truss bridge comprises a plurality of construction platforms arranged in the length direction of the steel truss bridge, a plurality of pushing devices and a steel guide beam arranged at the end of a box girder of the steel truss bridge. The pushing device comprises a sliding base fixedly arranged at the top of the construction platform, a pushing oil cylinder arranged on the sliding base, a plurality of jacking oil cylinders vertically arranged on the pushing oil cylinder, a limiting top plate arranged at the movable end of the jacking oil cylinder, a pushing rod arranged at the bottom of a box girder of the steel truss bridge and a hydraulic station assembly. The sliding base is arranged in the direction parallel to the length direction of the steel truss bridge, the pushing oil cylinder is connected with the sliding base in a sliding mode, a limiting groove consistent with the pushing rod in width is formed in the upper surface of the limiting top plate, and the hydraulic station assembly is communicated with the pushing oil cylinder and the jacking oil cylinder. The construction method has the advantages of high construction precision and high efficiency.
本申请涉及一种钢桁架桥的施工系统及其施工方法，属于钢桁架桥施工的技术领域。一种钢桁架桥的施工系统，包括多个沿钢桁架桥长度方向布设的施工平台、多个顶推装置、和设在钢桁架桥箱梁端部的钢导梁；所述顶推装置包括固定设在所述施工平台顶部的滑移底座、设在所述滑移底座上的顶推油缸、多个垂直设在所述顶推油缸上的顶升油缸、设在所述顶升油缸活动端的限位顶板、设在钢桁架桥箱梁底部的顶推杆和液压站总成；所述滑移底座沿平行于钢桁架桥长度方向设置，所述顶推油缸与所述滑移底座滑动连接，所述限位顶板上表面开设有与所述顶推杆宽度一致的限位槽，所述液压站总成与所述顶推油缸和所述顶升油缸连通。本申请具有施工精度高、效率高的优点。
