开敞式溢洪道抗冲耐磨混凝土配合比设计及施工

根据溢洪道消能方式、水流流态、流速等提出了高强度抗冲耐磨混凝土的相关技术指标,通过对当地材料及多种抗冲耐磨外加剂的对比试验分析,确定混凝土配合比,在施工中采取有针对性的施工方法和措施,使在高速过流面混凝土满足相关要求,文章通过配合比设计和施工方法的总结,望能对类似工程提供借鉴。

According to the energy dissipation mode, the flow state of water flow and the velocity of flow of the spillway, the re-lated technical indexes of high-strength and wear-resistant concrete are put forward, and the comparative test and analysis of localmaterials and various anti-impact and wear-resistant admixtures are carried out, the concrete mix ratio is determined, and targetedconstruction methods and measures are adopted in the construction, so that the concrete in the high-speed flow surface can meet therelevant requirements. This paper summarizes the mix ratio design and construction methods, in the hope of providing reference forsimilar projects.
