Bridge engineering construction method
The invention discloses a bridge engineering construction method which comprises the steps of preparation before construction, steel pipe pile construction, pile top distribution beam construction, bailey beam hoisting construction, bridge floor cross beam construction, bridge floor longitudinal beam construction and bridge floor steel plate and handrail construction. The bridge engineering construction method has the beneficial effects that the two pieces of 40b I-shaped steel which are parallel and transversely connected are adopted for the distribution beam and are used for transversely connecting the steel pipe piles, meanwhile, the load of the bridge floor is transmitted to the foundation of the steel pipe piles, so that the foundation is uniformly stressed, and the overall stability of the trestle is ensured; the lap joint of the longitudinal beam I-shaped steel and the cross beam I-shaped steel of the main trestle adopts a full-length welding mode; meanwhile, a bridge deck steel plate and longitudinal beam I-shaped steel are fully welded, so that lateral sliding of an upper structure is prevented; when the branch trestle and the steel platform are assembled through bailey beams, the branch trestle and the steel platform are limited through the limiting device. When the method is adopted for building the bridge, forming is fast, and the construction period is short.
本发明公开了一种桥梁工程施工方法，包括施工前准备、钢管桩施工、桩顶分配梁施工、贝雷梁吊装施工、桥面横梁施工、桥面纵梁施工、桥面钢板及栏杆施工。本发明的有益效果是：分配梁采用两根平行且横向连接的40b工字钢，用以横向连接钢管桩，同时传递桥面荷载到钢管桩基础，使基础均匀受力，保证栈桥的整体稳定性，主栈桥纵梁工字钢与横梁工字钢搭接处，采用满焊方式，同时桥面钢板与纵梁工字钢也采用满焊的方式，防止上部结构侧向滑动；支栈桥和钢平台采用贝雷梁拼装时，利用限位装置对其进行限位。而采用上述方法搭建桥梁，成型快，施工周期短。
