针对高山狭谷地区,双曲拱坝混凝土垂直及水平运输困难,重庆市巫溪县双通双曲拱坝体采用泵送混凝土浇筑,并运用温度控制仿真计算,控制施工浇筑温度及进度,很好地解决了坝体施工运输问题。坝体2011年建成以来,运行良好,混凝土各项技术指标检测均达到设计要求。泵送混凝土浇筑技术在高山狭谷地区值得推广运用。
In view of the alpine narrow valley, the vertical and horizontal transportation of double curved arch dam concrete is difficult. The double-arch double-arch dam body in Wuxi County of Chongqing Municipality is constructed by pumping concrete and temperature control simulation is used to control the temperature and progress of construction pouring. Well solved the dam construction and transportation problems. Since the completion of the dam in 2011, it has been operating well and all the technical indexes of concrete have met the design requirements. Pumping concrete pouring technology in the valleys of the mountains worth promoting application.
