The invention discloses a method for reconstructing and expanding a road under an existing operating railway bridge. The method is economical, efficient and safe in design and construction without interrupting railway operation, newly building a temporary railway and changing and moving an existing railway. The existing piers are reinforced to serve as auxiliary beam buttresses in the construction period, part of newly-built buttresses and old bridge bottom reinforcement are combined, it can be guaranteed that old bridge cutting and dismantling and new frame bridge jacking are conducted in order, and operation of existing railways is not affected. Old bridge bottom reinforcement and old pier reinforcement ingeniously solve the problem of construction auxiliary beam supporting points, and temporary reinforcement is high in economical efficiency, low in cost, safe and reliable. The method solves the problem that an existing method for transforming the road under the operating railway bridge is high in manufacturing cost.
本发明公开了一种既有营运铁路桥下道路改扩建方法，在不中断铁路运营、不新建临时铁路、不改移既有铁路，设计施工经济、高效、安全。加固既有桥墩使其在施工期间兼做便梁支墩，结合部分新建支墩及老桥梁底加固，可保证老桥切割拆除与新框架桥顶进有序进行，而不影响既有铁路运营。老桥梁底加固和加固旧墩巧妙的解决了施工便梁支点难题，临时加固经济性高、成本低且安全可靠。本发明解决了现有的既有运营铁路桥下道路改造方法存在造价高的问题。
