SO4 2-Deng red mud is to the pollution of environment based on alkali pollution.
Red mud dump uses filter cake dry method red mud stockpiling technique, main flow are as follows: contain filtering red mud to solid at present
After amount 67% or so, by filter cake automobile transportation to heap yarding.Dam body is generally first constructed when red mud pilling, then along stockyard week
The dry red mud transport routes of filter cake are built on side, then toward heap yarding red mud.
Red mud dump sanitary landifll difficulty is big at this stage, and stockyard massif side slope is often high gradient slope, and side slope is not easy out
Digging forms the measures such as Cut-off ditch and intercepts massif rainwater, this results in a large amount of massif side slope clear water to enter in stockyard and increase red mud
The rain flood pressure in stockyard.
Utility model content
In order to solve the above-mentioned technical problem the utility model provides a kind of filter cake dry method red mud storage yard slope drainage structure, mesh
Be to solve red mud dump high gradient slope not forming the reality of Cut-off ditch, effectively reduce into red mud dump rainwater, reduce
Red mud dump rain flood pressure, is conducive to red mud dump Recycle mechanism.
The technical solution of the utility model is as follows:
A kind of filter cake dry method red mud storage yard slope drainage structure, including the dam body constructed using the dry red mud of filter cake and along red mud
The dry red mud road of the filter cake that stockyard periphery massif side slope is constructed, the dry red mud road of filter cake go to red mud dump tail portion from the dam of dam body
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.
The utility model has the advantages of: the utility model, which solves red mud dump high gradient slope, can not form Cut-off ditch
It is practical, it effectively reduces into red mud dump rainwater, reduces red mud dump rain flood pressure, be conducive to red mud dump Recycle mechanism.
