冶勒水电站沥青混凝土心墙施工新工艺研究

Study on new technology of asphalt concrete core wall in Yele Hydropower Station

为克服气候条件的不利影响,冶勒水电站沥青混凝土心墙在施工前进行了十多次反复试验,总结出一整套冬季低温,夏季多雨、每日连续多层摊铺、每层铺筑厚度25 cm的施工新工艺,使沥青混凝土心墙的铺筑每天可上升0.5 m,加快了施工进度,取得了比较满意的结果。

To overcome the adverse cilmatic conditions, more than ten tests had been made repeatedly before the construction of the asphalt concrete core wall of the dam. Through these tests, some new construction techniques have been gained. These technologies solved such problems as low temperature in winter and rainy climate in summer in the construction. In any weather, continuous multi-layer pouring per day has been achieved and the pouring thickness per layer reaches twenty-five centimeter. Thus the height of the asphalt concrete core has been heightened 0.5 meter every day, so the construction speed has been accelerated and the pouring results has been gained acceptably.
