为满足金塘大桥工程百年使用寿命的耐久性要求,在试桩承台、墩座、塔座、塔柱及墩身底部等结构部位均采用了环氧树脂涂层钢筋。根据环氧树脂涂层在施工中容易损坏,对现场操作的要求高等特点,在施工过程中我们反复试验摸索,采取了一系列应对措施。文中简要介绍了涂层钢筋的施工质量控制方法,以期能给类似工程提供一些经验。
In order to meet the durability requirements of 100-year service life of Jintang Bridge Project, epoxy-coated steel bars are used in the structural parts of test pile cap, piers, pylons, pylons and piers. According to the epoxy coating in the construction of easily damaged, the requirements of the operation of the higher characteristics of the construction process, we repeatedly trial and error to explore and adopted a series of countermeasures. This paper briefly introduces the construction quality control methods of coated steel bars, with a view to providing some experience for similar projects.
