在已建成的小型水库中,大多数坝基均存在渗漏问题。目前,一般都采用心墙、铺盖以及斜墙等防渗结构,但效果均不理想。俄罗斯利用生物技术研制出人造潜育土防渗墙,防渗效果好,是值得在小型水库和渠道工程中推广的一种新型防渗结构形式。人造潜育土是用粉碎的植物与当地粘土按一定的配合比组成的活性土。它的防渗原理是:在水中,植物里的厌氧菌繁殖迅速,可使活性土 In the completed small reservoirs, most of the dam bases have leakage problems. At present, the impervious structures such as the heart wall, the bedding cover and the inclined wall are generally used, but the effects are not satisfactory. Russia used biological technology to develop artificial seepage cutoff walls with impervious effect and is a new form of impervious structure that is worth popularizing in small reservoirs and channel projects. Artificial jaundice soil is crushed plants and local clay by a certain proportion of active soil composition. Its anti-seepage principle is: in the water, plant anaerobic bacteria multiply rapidly, can make active soil
