水工建筑物下游反滤层的设置,有两种型式:一种是水平铺设,如涵闸下游护坦底部的反滤层。另一种是倾斜铺设,如扬水站压力池下部护坡底部的反滤层。水平铺设的反滤层,施工比较容易。但设置在斜坡上的反滤层,施工中如果控制不好,往往会出现各层反滤料互相掺杂的现象,会影响反滤效果。所以必须采取有效的施工措施,防止这一弊病的产生。我县王信扬水站压力池前部1:1的斜坡上,设置三层反滤料(图1)。在反滤层
There are two types of anti-filtration layers in the downstream of a hydraulic structure: one is a horizontal anti-filtration layer that is laid horizontally, such as the bottom of a retaining gate downstream of the culvert. The other is inclined laying, such as pumping station bottom of the pressure tank bottom of the anti-filtration. The horizontal laying of the filter, the construction easier. But set in the slope of the anti-filter layer, if the construction is not well controlled, there will often be layers of anti-filter material doped with each other, will affect the filter effect. Therefore, we must take effective construction measures to prevent the occurrence of this malady. My county Wang Xin Yang water pressure in front of the pool 1: 1 slope, set three layers of filter material (Figure 1). In the filter layer
