预应力混凝土节段式连续梁是近年来国际上最盛行的一种桥梁型式,它的安装工艺也在发展创新。逐孔节段拼装工艺是继悬臂拼装、悬臂浇筑、顶推法、PZ法、逐孔现浇之后的一项新工艺。在我国这项新工艺首次在福州洪塘大桥得到实现。施工实践证明,该方法简单、方便、安全、快速。一、基本情况1.福州洪塘大桥是316国道起点,位于
Prestressed concrete segment continuous beam is the most popular in recent years, a bridge type, its installation process is also developing innovation. Hole-by-hole segment assembly process is a new technology after cantilever assembly, cantilever pouring, pushing method, PZ method, hole-by-hole pouring. In our country, this new craft is realized for the first time in Fuzhou Hongtang Bridge. Construction practice has proved that the method is simple, convenient, safe and fast. First, the basic situation 1. Fuzhou Hongtang Bridge is the starting point of State Road 316, located
