防渗渠道漏水少我们对全县三种不同土质渠道进行防渗对比试验,结果:1.砂壤土渠50米,渠首流量88米~3/时,渠尾流量64米~3/时,渠道利用系数73%,当改成水泥石子砂子(1:2:4)防渗渠道后,渠道利用系数提高到98%。2.黑粘土渠200米,渠首流量13米~3/时,渠尾流量7米~3/时,改成水泥防渗渠后,渠道利用系数由54%提高到91%。3.山丘土渠150米,改成石渠 Leakage prevention seepage channel We compare the three different soil quality of the county impermeable control test results: 1 sand soil channel 50 meters, canal flow of 88 meters to 3 / hour, when the tail flow of 64 meters to 3 / hour, Channel utilization factor of 73%, when converted to cement gravel sand (1: 2: 4) seepage control channels, the channel utilization factor increased to 98%. 2. After 200m of black clay drainage and 13m ~ 3 / d of canal flow, drainage flow of 7m ~ 3 / h is changed to cement impermeable canal, the coefficient of channel utilization is increased from 54% to 91%. 3. Hill soil 150 meters, replaced by stone canals
