谈桥梁下部构造的施工技术

Talking about the construction technology of bridge lower structure

结合伊丹河桥工程实例,介绍了公路桥梁下部构造施工前的准备工作,研究了桥梁下部结构钻孔桩施工、钢筋骨架的安装与水泥混凝土施工,探讨了公路桥梁下部构造桥墩与桥梁下部构造桥台施工技术,期望能够有效的提升我国公路桥梁工程的质量与效率,为之后桥梁下部构造施工技术的探讨提供参考。

Based on the example of the bridge project of the Edan River,this paper introduces the preparatory work before the construction of the lower part of the highway bridge. The construction of the bored pile,the installation of the reinforcement skeleton and the cement concrete construction are studied. The construction technology of the bridge pier in the lower part of the highway bridge and the construction technology of the bridge abutment construction are discussed. It is effective enough to improve the quality and efficiency of highway and bridge engineering in China,so as to provide reference for the construction technology of the lower part of the bridge.
