苏刊《水工建设》1987年7期报道:对水电站机械设备的调查情况表明,在高水头(超过120m)下,传统的橡胶止水是不够可靠的。莫斯科水工金属结构设计院专业设计处通过试验证实,装有高压聚乙烯(15803—020 OCT16337—77)止水的闸门能在200m和更高水头下可靠地封闭水工建筑物
Su Journals “Hydraulic Construction” 1987Year 7Report: Investigation of hydropower station machinery and equipment shows that in the high water head (more than 120m), the traditional rubber water stop is not reliable enough. Professional Design Office of Moscow Hydraulic Metal Structure Design Institute confirmed through experiments that the gate equipped with high-pressure polyethylene (15803-020 OCT16337-77) water-stop can reliably close the hydraulic structure under the pressure of 200m and higher
