塞浦路斯的南方输水系统是一项投资几百万美元的工程,包括:建一条14.5km长的隧洞,改变德雷索斯(Dhiarizos)河的河道;建几道坝;铺设管道系统,以便把水输送到塞浦路斯的首都尼科西亚和法马古斯塔市。这个输水系统对于解决塞浦路斯夏季所面临的缺水问题,做出了巨大的贡献。隧洞的现浇砼里衬原来规定是用抗硫酸盐水泥的,然而在隧洞打通之前,才知道塞浦路斯仅有的两家水泥厂都不生产抗硫酸盐水泥了。塞浦路斯的水利发展部坚持隧洞里衬中的砼,必须具有良好的抗硫酸盐和氯化物的性能。从隧洞里取出的水样,确实发现其硫酸盐和
The southern delivery system in Cyprus is a multimillion-dollar project that includes the construction of a 14.5-km long tunnel to change the course of the Dhiarizos river, the construction of several dams, and the laying of piping systems Water is delivered to the cities of Nicosia and Famagusta, the capital of Cyprus. This water delivery system has made a significant contribution to solving the water shortage in the summer of Cyprus. In-situ concrete lining of the tunnel was originally provided with anti-sulfate cements but before the tunnel was opened, it was not known that the only two cement plants in Cyprus did not produce sulfate-resistant cement. The Ministry of Water Resources and Development in Cyprus insists on the concrete in tunnel linings and must have good resistance to sulphate and chloride. The water sample taken from the tunnel did find its sulfate and salt
