随着桥梁施工技术的不断提高,高墩、深桩、大体积混凝土、大跨度桥梁技术被广泛应用在桥梁施工中,其要求基础的结构尺寸不断增加,进而使得大体积基础的施工成为控制工程进度、安全、质量的重要因素。文章就新建黄织铁路歹阳河大桥6~#、7~#墩大体积嵌岩基础的混凝土施工技术、混凝土防裂和混凝土温度控制等谈几点体会。
With the continuous improvement of bridge construction technology, high pier, deep pile, large-volume concrete, long-span bridge technology is widely used in bridge construction, the basic structural dimensions of which are increasing, thus making large-volume foundation construction a control project Progress, safety, quality of the important factors. The paper talked about the concrete construction technology of large rock mass embedded rock foundation of No. 6 ~ #, No. 7 ~ # Pier of Huangyangzi Railway, cracking prevention of concrete and concrete temperature control.
