介绍了灌河大桥主桥桩基钢筋笼主筋净距小,钢筋笼长度大,对接节段数量多及吨位大等特点,对钢筋笼施工中关键的吊点的加固及打梢施工工艺进行了介绍。并通过在施工中的应用,证明了该施工工艺是成功的,不但操作简便,安全可靠,而且大大提高了工作效率。 This paper introduces the characteristics of the main reinforcement, such as the small spacing, the length of the reinforcement cage, the large number of butt joints and the large tonnage of the main reinforcement of the main reinforcement of the main bridge of the main bridge in the Irrigation Bridge. The reinforcement and the construction of the key lifting points in the construction of the reinforcement cage are carried out Introduction. And through the application in the construction, the construction process is proved to be successful, not only easy to operate, safe and reliable, but also greatly improve work efficiency.
