摘要
安徽怀远涡河三桥主桥为钢管混凝土系杆拱桥 ,采用整体安装与分段不对称安装相结合的方法 ,将合拢段放在拱座内 ,合理地消化前部施工引起的累计误差。拱肋内混凝土采用具有自流、自平、自密实等特点的混凝土配比 ,简化了钢管混凝土灌注工艺。
The main bridge of Anhui Huaiyuan Wohe River No 3 Bridge is steel pipe concrete tied arch bridge, adopted the construction method combining integral installation with asymmetric segmentation installation. It was locked in the abutment of arch to remove accumulative construction error. Concrete used in arch\|rib had the mixture ratio with such features as self\|floating, self\|planing and self\|compactablity to simplify the pouring method of steel pipe concrete.
