Construction method for quick dismantling structure of overline overbridge
The invention relates to a construction method of a quick demolition structure of an overline overbridge. The construction method comprises the steps that the positions of all cutting parts and cutting positioning devices of the bridge are determined; installing a shaped protective fence structure and traffic guidance and modification; paving an under-bridge pavement protection structure; mounting a supporting frame at the bottom of the bearing inclined arch leg; assembling a bearing inclined arch leg, chiseling away and removing an isolation protection bracket; mounting a protective suspension bracket; a half-range road closure steel supporting structure is installed; a bridge jacking prepressing support structure is erected, and beam body structure form conversion is completed; mounting a crash barrier cutting and dismantling bracket and a crash barrier cutting and stabilizing bracket; mounting a crash barrier cutting guide frame; a movable support supporting structure is arranged; the reinforced concrete crash barrier is dismantled; arranging an advanced demolition plate lifting-away demolition device; cutting and hoisting the plate which is dismantled in advance; the bearing arch legs are dismantled; and dismantling and transporting the main beam and the bridge abutment. The demolition construction efficiency is improved, construction safety is guaranteed, influences on the environment and traffic are reduced, and the method has the advantages of being short in construction period, small in influence on traffic, high in safety and the like.
本发明涉及跨线天桥快速拆除结构的施工方法，包括确定桥梁各切割部位及切割定位装置的位置；安装定型化防护围挡结构及交通导改；铺设桥下路面保护结构；安装承重斜拱腿底部支撑架；拼装承重斜拱腿凿除拆除隔离保护支架；安装防护悬挂架；安装半幅封路钢支撑结构；搭设桥梁顶升预压支架结构并完成梁体结构形式转换；安装防撞栏切割拆除支架及防撞栏切割稳固支架；安装防撞栏切割导向架；布设移动支架支撑结构；拆除钢筋混凝土防撞栏；布设先行拆除板吊离拆除装置；切割及吊运先行拆除的板；拆除承重拱腿；拆除及运输主梁和桥台。本发明提高了拆除施工效率和保证施工安全，减少对环境和交通的影响，具有施工工期短、对交通影响小、安全性高等优点。
