用碾压法建筑混凝土坝的技术,在国外已有不少研究。这种方法的特点是坝体内部使用干硬性贫混凝土、大面积通仓薄层铺筑和用震动压路机碾压震实。它是对柱状浇筑施工方法的一次革命,其优点是能大量节约模板和接缝灌浆工作量,从而节约投资、缩短工期,而且由于水泥用量较少,铺筑层薄,减少了水化热温升,使坝体温度状况改善,可大大简化温控措施。 The technology of building concrete dam by rolling method has been studied abroad. This method is characterized by the use of dry and hard lean concrete inside the dam, a large area of ​​the storey floor paved and vibrated roller compacting. It is a revolution of the column pouring construction method, which has the advantage of saving a great deal of template and joint grouting workload, thus saving investment and shortening the construction period, and because the amount of cement is less, the paving layer is thin, the hydration heat temperature is reduced L, so that dam body temperature conditions improve, can greatly simplify the temperature control measures.
