富阳县岩石岭水库总干渠,是岩石岭水库的配套工程,它既是四万亩农田的灌溉渠道,又是岩石岭二级电站的引水渠道。渠长6560米。设计流量16.5秒立米,校核流量18秒立米,流速0.65秒米,渠道比降七千五百分之一。花坞口渠段长60米,横跨花坞,系全部用石渣填筑的填方渠道,填筑高度9.70米,边坡系数为1.5和1.75。原方案用1.0米厚的黄泥辅盖,斜墙防渗。1983年5月28日通水后,至1983年9月初,一直渗漏严重,较大的管涌出现了四次,其中最大的一次,在渠床下面出现直径70厘米左右的大漏洞;并不断出现纵阳裂缝,危及工程安全。渠道停水修复几次,渗漏问题一直得不到解决,使渠道不能正常运行,二级电站不能正常发电。
The main channel of the Rocky Ridge Reservoir in Fuyang County is a supporting project of the rock ridge reservoir. It is not only an irrigation channel for 40,000 mu of farmland, but also a diversion channel for the Second Rocky Ridge Power Station. Channel length 6560 meters. The design flow of 16.5 seconds, check the flow of 18 seconds of legislation, the flow rate of 0.65 seconds, the channel down one-five-one-fifth. The flower dock channel 60 meters long, across the flower dock, all filled with gravel fill channels, filling height of 9.70 meters, the slope factor of 1.5 and 1.75. The original program with 1.0 m thick yellow mud auxiliary cover, inclined wall seepage. After the water was passed on May 28, 1983, by mid-September 1983, there was a serious leakage and the occurrence of larger pipework occurred four times. The largest of these was a large hole of about 70 centimeters in diameter under the canal bed; Longitudinal cracks appear, endangering the safety of the project. Water channel repair several times, the leakage problem has not been resolved, so that the channel can not be normal operation, two power plants can not be normal power generation.
