古郊河大桥现浇板支架施工技术

On cast-in-place support construction technique of Gujiao River Bridge

以古郊河大桥支架施工为例,从支架与底模设计、荷载计算、纵桥向工字钢验算、钢管桩强度与稳定性验算等方面,介绍了该工程的具体施工方案,并总结了桥梁现浇板支架施工中的注意事项,保证了桥梁施工质量,节约了成本。

Taking the support construction of Gujiao River Bridge as the example,the paper,from the support and bottom die design,loading calculation,the calculation of longitudinal I-shaped steel,and strength of steel pipe piles and stability calculation,introduces the construction schemes for the project,and sums up some precautions in the cast-in-site support construction,so as to ensure the bridge construction quality and save cost.
