三峡二期大坝和电站厂房施工是三峡工程中最艰巨的项目之一,混凝土浇筑量大、工期紧、施工强度高、温控要求严,如何合理布置混凝土拌和系统并选择经济合理的技术参数,是关系工程成败的大事。经过几年的运行实践表明,三峡二期混凝土拌和系统设计、建设是成功的。 Construction of the Three Gorges Dam and Powerhouse is one of the most difficult projects in the Three Gorges Project. The concrete pouring capacity is large, the construction period is tight, the construction intensity is high, the temperature control is strict, how to arrange the concrete mixing system rationally and select the economic and reasonable technical parameters , Is a matter of success or failure of the project. After several years of practice shows that the Three Gorges Project two concrete mixing system design and construction is successful.
