青银公路分离立交钢管混凝土拱桥施工

The construction of separated cross tubular concrete arch bridge

介绍了青银公路分离立交钢管混凝土拱桥施工方案。从钢管拱肋制造安装、横梁预制吊装、钢管混凝土灌注工艺等方面进行了详细的论述 ,经检测 ,保证了安装精度和灌注密实度 ,并确保了工期 ,降低了费用。

combined with Qingying road, the construction plan of separated cross tubular concrete arch bridge is in detail introduced. At the same time the fabrication and installing of steel pipe arch rib, the pre-fabrication and hoisting of beam, the pouring crafts of the tubular concrete and so on are expounded. The actual project had proven that this construction plan guaranteed the precision of installing and the degree of density of pouring, ensured time limit and abated cost.
