摘要
采用静水法对复合式防渗渠道、卷板式 U形混凝土渠道和滑模现浇 U形混凝土渠道的防渗效果进行了测试 ,其渗漏强度分别为 1 .92、7.1 3和 1 .6 8L/( m2 · h) ,分别比对应土渠降低 95 .5 %、71 .7%和 95 .8%。
The permeability of three types of impervious canals is measured with ponding test method. The three types of canals are: ① composite material impervious canal; ② U-shape prefabricated concrete canal; ③ U-shape cast-in-site concrete canal. The measurement results of permeability for the three types of canals are 1.92, 7.13, and 1.68 L/(m 2·h) respectively, and are 95.5%, 71.7%, and 95.8% less than corresponding soil canals respectively.
