The invention discloses a dismounting and transporting integrated device and dismounting and transporting method for an existing expressway arched overbridge main arch, and belongs to the technical field of bridge engineering construction.The dismounting and transporting integrated device comprises two top-layer steel pipe supports, and the lower ends of the top-layer steel pipe supports are connected with middle-layer steel pipe supports; the end, away from the top-layer steel pipe support, of the middle-layer steel pipe support is connected with a bottom-layer steel pipe support, the end, away from the middle-layer steel pipe support, of the bottom-layer steel pipe support is connected with a leveling steel plate, and a self-propelled hydraulic module vehicle set is installed at the lower end of the leveling steel plate and comprises a plurality of self-propelled hydraulic module vehicles. The end, away from the middle-layer steel pipe support, of the top-layer steel pipe support is connected with a plurality of hydraulic winches. The whole device is simple in structure, material processing and equipment assembling are convenient, reliability is high, economical efficiency is high, the device can be repeatedly used on dismantling projects of similar arched overbridges of existing expressways, and the problem that batch flow construction cannot be achieved in a traditional bridge dismantling mode is solved.
本发明公开了一种既有高速公路拱形天桥主拱的拆运一体装置及拆运方法,属于桥梁工程建造技术领域,拆运一体装置包括顶层钢管支架,顶层钢管支架有两个,顶层钢管支架的下端连接中层钢管支架,中层钢管支架远离顶层钢管支架的一端连接底层钢管支架,底层钢管支架远离所述中层钢管支架的一端连接找平钢板,找平钢板下端安装有自行式液压模块车组,自行式液压模块车组包括数个自行式液压模块车,顶层钢管支架远离所述中层钢管支架的一端连接有数个液压绞车。本发明整个装置结构简单,材料加工和设备组装方便,可靠性高,经济性强且能在既有高速公路同类拱形天桥拆除项目上重复利用,解决了传统拆桥模式无法批量流水施工的问题。
