Hexi Reservoir Project, applying filter design, is introduced, which is made up of clay central core and sandy gravel dam according to the gradation curve of clay and gravel.
介绍了合溪水库工程的概况，选用坝型为粘土心墙砂砾石坝，根据粘土和砂砾石料场的颗分曲线，对反滤料进行了设计。
Considering the structural characteristics of the impervious components of the dam, several types of filter are set up in the design.
在大坝设计过程中，根据大坝防渗体结构的特点，设计了包括控制性反滤和非控制性的多层反滤组合。
Compared with with other part, the area near overflow point could be more easily destructed. Therefore, the filter protection to the downstream of the primary dam should be done early.
各种工况下的渗流溢出点附近相对于整个坝体其它部位更易于发生渗透破坏，故应做好初期坝下游坝坡的反滤保护。
The clear water I, II, III are recycled in the subsequent production flow. The ore is used for constructing dam. The filter residues are removed for dry stack or burned for building bricks.
清水一、清水二和清水三可直接进入后续生产流程循环利用，矿沙用于堆积筑坝，滤渣可运走干堆或烧制建筑用砖。
