Direction is constructed, and is equipped with gutter in excavation of the dry red mud road of filter cake by massif side slope side, the row of laying in gutter
Ditch HDPE geomembrane, gutter HDPE geomembrane are welded to connect by massif side slope side and slope seepage control layer HDPE geomembrane,
Gutter HDPE geomembrane is anchored by stockyard side on the dry red mud road of filter cake and through anchoring groove.
Gutter on the dry red mud road of filter cake connects with the dam abutment gutter of dam body.
A kind of construction method of filter cake dry method red mud storage yard slope drainage structure, includes the following steps:
Step 1, dam body is constructed with the dry red mud of filter cake；
Step 2, the dry red mud road of filter cake is constructed along red mud dump massif side slope, the dry red mud road of filter cake goes to stockyard from dam
Caudal directions are constructed, and the dry red mud road of filter cake is kept in certain drainage grade slope aspect red mud dump and dam body；
Step 3, gutter is excavated by massif side slope side along the dry red mud road of filter cake, gutter, which is excavated, keeps one away from side slope
Set a distance；
Step 4, HDPE geomembrane in gutter is laid in gutter；
Step 5, HDPE geomembrane in gutter is welded to connect by massif side slope side and slope seepage control layer HDPE geomembrane；
Step 6, by stockyard side, the excavation and anchorage ditch on the dry red mud road of filter cake anchors gutter HDPE geomembrane；
Step 7, after the completion of above-mentioned steps, the gutter formed will be excavated and connected with dam abutment gutter, massif rainwater is arranged
To outside red mud dump；
Step 8, it when constructing next stage red mud fill dam, repeats the above steps until the final absolute altitude of red mud dump, maximum
The guarantee rainwater of limit does not enter in red mud dump.
Advantages of the present invention effect: the present invention, which solves red mud dump high gradient slope, can not form the reality of Cut-off ditch, have
Effect, which is reduced, enters red mud dump rainwater, reduces red mud dump rain flood pressure, is conducive to red mud dump Recycle mechanism.
