观音岩水电站工程地处我国西南地区,施工期间遇到高温季节长、昼夜温差大等温控技术难题。本工程在高温季节施工中,从原材料、出机口、运输过程、浇筑振捣、养护等环节采取了有效温度控制措施;高温差季节时段采取麻包装含泥砂保护等措施,解决了目前抗冲耐磨混凝土施工的温控技术难题,为抗冲耐磨混凝土在温控施工方面积累了经验。文章重点介绍抗冲耐磨混凝土温控措施和高温差季节保护措施。
Guanyinyan Hydropower Station project is located in China’s southwestern region, encountered during the construction of high temperature season, temperature difference between day and night temperature control and other technical problems. The project in the high temperature season construction, from the raw materials, the machine out of the mouth, transportation process, pouring vibration, conservation and other sectors to take effective temperature control measures; high temperature difference season to take hemp packaging sand and sand protection measures to solve the current impact Wear-resistant concrete construction temperature control technology problems for the impact of abrasion-resistant concrete construction has accumulated experience in temperature control. The article focuses on the temperature control measures of impact and abrasion resistance concrete and seasonal protection measures of high temperature difference.
