Large-span overpass integrally hoisted on single sides of multiple underpass railway business lines, and construction method thereof
The invention relates to a large-span overpass integrally hoisted on the single sides of multiple underpass railway business lines. The large-span overpass comprises an overpass mid-span, overpass side-spans, reinforced concrete stand columns, fixing and positioning devices and the multiple railway business lines. The large-span overpass is of a steel truss structure undercrossing multiple railwaybusiness lines and comprises the overpass mid-span and the overpass side spans, the overpass mid-span is fixed to the reinforced concrete stand columns through the fixing and positioning devices, andthe overpass side spans are positioned and fixed through the fixing and positioning devices. The integrally-assembled large-span steel truss overpass is prefabricated by adopting engineering, integral assembling is carried out on site, and finally hoisting is performed by using a large-tonnage crane, so the steel truss overpass is convenient to assemble and short in installation period, the application time of an existing line construction window is shortened, the existing line is changed into a non-existing line in upper construction, the influence on an operation line is greatly reduced, and considerable social benefits and high popularization value are achieved.
本发明涉及下跨多条铁路营业线单侧整体吊装大跨度天桥，包括天桥中跨、天桥边跨、钢筋混凝土立柱、固定定位装置和多条铁路营业线；大跨度天桥为下跨多条铁路营业线的钢桁架结构，大跨度天桥包括天桥中跨和天桥边跨，天桥中跨通过固定定位装置固定在钢筋混凝土立柱上，天桥边跨通过固定定位装置进行定位固定。本发明的有益效果是：本发明整体拼装大跨度钢桁架天桥采用工程预制，现场整体拼装，最后利用大吨位吊车吊装的方案，钢桁架天桥拼装便捷，安装周期短，减少了既有线施工窗口申请时间，使上部施工变既有线为非既有线，大大减少了对运行线路的影响，具有可观的社会效益和较高的推广价值。
