4)  sand case dam with clay core
粘土心墙砂壳坝
1.
Analyses of the monitored seepage data of the sand case dam with clay core of Jilihe Reservoir show that the impervious effect of the clay core is good, that the blanket in the front of the dam has little impervious effect, and that seepage failure will probably take place because of the weak cutoff groove and the large seepage gradient.
对吉利河水库粘土心墙砂壳坝的渗流观测资料分析表明,该坝粘土心墙的防渗效果较好,但坝前铺盖没起到防渗作用,且截渗槽较薄弱,渗透比降较大,可能发生渗透破坏。

补充资料:砂壳虫属
      原生动物门肉鞭动物亚门根足纲表壳目砂壳科的 1属,通称砂壳虫。大小因种类而异,30~300微米不等(见图)。除和变形虫一样能伸出片状或叶状的伪足外,整个原生质包在一个硬壳内。壳内层有几丁质膜,外面粘附着由矿物屑、岩屑、砂粒、硅藻空壳等构成的粗糙表层。壳呈半球形、卵圆形、梨形等。有的壳向前延伸成颈,有的壳冠突出几个长角,也有的壳覆盖着桑椹状的突起。壳的横切面大都呈圆形。口在壳体的一端,位于主轴正中。壳口的外缘有的光滑、有的齿状、有的分成3~4叶瓣状。虫体摄食或行走时,可伸出2~6个指状伪足,把壳体顶起,象蜗牛似地在基质上爬行。遇刺激或敌害时,伪足立即缩入壳内。细胞质占壳腔的大部分,用原生质线固着于壳的内壁。核一般只有1个,伸缩泡1至多个。
  
  砂壳虫分布在淡水的池塘、湖泊、沼泽、水库以及森林土壤中。如在中国长江中下游湖泊中常见的冠砂壳虫。砂壳虫可作为鱼类的饵料。
