3、各种桥梁断面。当桥梁宽度，节段高度，翼板厚度发生变化时调整十分方便。,一般适用节块长度为3-5米，重量100-400吨。使用液压系统推进。横坡纵坡均可调整。 预制节块拼装挂蓝几乎可适用于未来项目的任何断面。,预制节块拼装用挂蓝,世界跨度最长的混凝土悬臂梁桥,重量轻: The use of rectangular hollow sections in the main structural components and recoverable high strength bars in all stays and ties reduces the total steel weight to a
4、minimum. 使用灵活: The Bridgebuilder may be adapted to almost any cross-section and is easily adjustable during operation to variations in segment length, box height, web thickness, deck width and road alignment (gradient, curvature, super-elevations). 挠度小: The vertical deflection at the front of the Br
5、idgebuilder is less than 25 mm at maximum load. Formwork beams are designed for a maximum deflection of L/400 of their length. 安装快捷: One Bridgebuilder may be assembled in one week.
