Abstract
This invention discloses one red earth bump level anti-transparency layer and discharge shaft connection method and its structure, which comprises the following steps: setting concaved tank on discharge shaft and ring edge in concaved tank; then processing level anti-transparency pad layer with top part align to ring edge; then paving compound geomembrane; then drilling concrete into concaved tank; finally processing anti-transparency protection layer.
Description
Technical field:
The present invention relates to the method for disposal of a kind of alumina producer waste water processing station mud, belong to the alumina producer technical field of waste water processing.
Technical background: technical field:
The present invention relates to a kind of method of attachment and structure that is applicable to red mud dump horizontal impervious layer and draining shaft, belong to red mud dump seepage control technique field.
Background technology:
Be the protection environment, prevent that wastewater from red mud from leaking, red mud dump is provided with impervious barrier.What generally adopt is to be the horizontal leakage preventing mode of core with artificial impervious material-composite geo-membrane.The composite geo-membrane bottom is provided with bed course, and top is provided with topping.
Draining shaft is one of key facility of red mud dump collection wastewater from red mud.Draining shaft can join with horizontal impervious layer inevitably in work progress.The plastics geomembrane is that strip is laid, and vertical shaft is cylindrical steel structure or reinforced concrete structure, both realize difficulty of seamless link, and horizontal impervious layer and draining shaft can produce the difference in the sedimentation under following red mud weight, and the junction easily produces the crack and causes wastewater from red mud along the borehole wall contaminated environment that leaks.
Summary of the invention:
For addressing this problem, the present invention proposes a kind of method of attachment and structure that is applicable to red mud dump horizontal impervious layer and draining shaft, can effectively solve the sealing of junction and the leakage problem that uneven settlement of foundation causes.
The present invention is achieved in that
Groove (2) is set on draining shaft (1); groove (2) is provided with annular edge (3); bed course (4) in the construction level impervious barrier then; its top is concordant with annular edge (3); re-lay composite geo-membrane (5); placing of concrete in groove (2) afterwards, TOC is concordant with annular edge (3), the clay topping (6) of the impervious barrier of constructing at last.
Composite geo-membrane (5) is gone up inflection once in annular edge (3), and the sidewall along groove (2) is routed to groove (2) bottom always then.
Joint construction of the present invention: go up connection groove (2) at draining shaft (1), the outside of groove (2) is provided with annular edge (3); Bed course in the horizontal impervious layer (4) be in annular edge (3) below, its top is concordant with annular edge (3); Composite geo-membrane (5) is between bed course (4) and the clay topping (6), is layer of concrete in groove (2).
Groove (2) is a square, and its material is identical with draining shaft (1), and as a whole with draining shaft (1).
Groove (2) degree of depth is 0.8～1.2m.
It is simple that the present invention has job practices, and antiseepage is put Lou effective, can effectively solve the sealing of red mud disposal drainage shaft and horizontal impervious layer junction and the leakage problem that uneven settlement of foundation causes.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment:
Square indentations (2) is set on draining shaft (1), and its material is identical with vertical shaft.Groove (2) is as a whole with draining shaft (1).If draining shaft (1) is a steel work, then groove (2) is made of steel plate; If draining shaft (1) is a reinforced concrete structure, then groove (2) is also made of steel bar concrete and is together constructed with vertical shaft.Groove (2) degree of depth is about 1m.
Groove (2) outside is provided with annular edge (3).Its width is estimated according to settlement of foundation.
Bed course (4) in the construction level impervious barrier then, its top is concordant with annular edge (3).
Re-lay composite geo-membrane (5).Composite geo-membrane is gone up inflection once in annular edge (3), and the sidewall along groove (2) is routed to groove (2) bottom always then.Placing of concrete in groove (2) afterwards, TOC is concordant with annular edge (3).
Construct the at last clay topping (6) of impervious barrier is finished whole impervious barrier construction.
