Abstract
The utility model discloses an anchoring structure of a tailings reservoir preliminary dam top leakproof geomembrane. A groove (2) is dug at one side of the inner slope of a dam body which needs the leakage prevention; the leakproof geomembrane (3) is paved along the inner wall of the groove (2); a landfill concrete layer (4) is cast on the leakproof geomembrane (3); and the landfill concrete layer (4) is filled in the whole groove (2). Compared with the prior art, by forming kinks in the groove which is dug at the dam top of the preliminary dam of the tailings reservoir, after the groove is filled with the landfill concrete layer, the leakproof geomembrane can realize rigid connection between the leakproof geomembrane and the preliminary dam top, greatly improves reliability, and further guarantees the rigidity and the reliability of the connection between the leakproof geomembran and the preliminary dam top since the landfill concrete layer and a road around the dam are simultaneously integrally cast with the same grade concrete.
Description
Technical field
The utility model relates to the anchor structure of a kind of mine tailing storehouse initial stage dam crest anti-seepage geomembrane, belongs to initial stage dam crest seepage control technique field, mine tailing storehouse.
Background technology
In alumina mine tailing storehouse; for the seepage that prevents wastewater from red mud pollutes environment; need in the stockyard, reach mine tailing storehouse initial dam inner slope anti-seepage geomembrane is set; and the anti-seepage geomembrane anchoring of dam crest in the early stage is a critical boundaries condition of place antiseepage, and the reliability of its anchoring is significant to the antiseepage and the environmental protection that realize the place.Present existing anchoring is that anti-seepage geomembrane is directly anchored into initial stage dam crest certain depth; this kind method has realized being articulated and connected of anti-seepage geomembrane and initial stage dam crest; but reliability is low; geomembrane is pulled out possibility under external force, is the extremely unfavorable factor of the whole antiseepage and the environmental protection of place.
The utility model content
Technical problem to be solved in the utility model is, the anchor structure of a kind of mine tailing storehouse initial stage dam crest anti-seepage geomembrane is provided, to solve the anchoring problem of mine tailing storehouse initial stage dam crest anti-seepage geomembrane and initial stage dam crest, realize both being rigidly connected, improve the connection reliability.
The technical solution of the utility model: need the dam body inner slope one side excavation of antiseepage fluted in the early stage on the dam, be equipped with anti-seepage geomembrane along the inwall of groove, be cast with the landfill layer of concrete on anti-seepage geomembrane, the landfill layer of concrete fills up whole groove.
The dam crest on dam is provided with dam crest ring field road in the early stage, and dam crest ring field road and landfill layer of concrete are to use that the concrete of same numeral is integrated poured to be obtained.
Compared with prior art, the utility model anti-seepage geomembrane forms bending in the groove of the dam crest excavation of mine tailing storehouse initial dam, after tamping with the landfill layer of concrete, can realize being rigidly connected of anti-seepage geomembrane and initial stage dam crest, significantly improved the connection reliability, it is integrated poured that the concrete of landfill layer of concrete and dam crest ring field road employing same numeral carries out the while, then further guaranteed rigidity and reliability that anti-seepage geomembrane is connected with the initial stage dam crest.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
The specific embodiment
Embodiment of the present utility model: the anchor structure of this mine tailing storehouse initial stage dam crest anti-seepage geomembrane, as shown in Figure 1, comprise initial dam 1, need dam body inner slope one side of antiseepage to excavate fluted 2 in the early stage on the dam 1, inwall along groove 2 is equipped with anti-seepage geomembrane 3, be cast with landfill layer of concrete 4 on anti-seepage geomembrane 3, landfill layer of concrete 4 fills up whole groove 2, and its dam crest ring field road 5 and landfill layer of concrete 4 are to use that the concrete of same numeral is integrated poured to be obtained.
Implementation step of the present utility model is as follows:
The first step
When initial dam 1 is built a dam to the dam crest position, need the inner slope one side excavation groove 2 of antiseepage at dam body, the geometry of groove 2 is seen shown in Figure 1, concrete size should be according to calculating such as the relevant mechanical property of anti-seepage geomembrane 3 such as tensile strength;
Second step
After groove 2 excavations finish, carry out the laying of anti-seepage geomembrane 3, and anti-seepage geomembrane 3 is involved in the groove 2 by shown in Figure 1;
The 3rd step
With concrete groove is tamped and to obtain landfill layer of concrete 4; Generally speaking, dam crest is provided with a ring road 5, landfill layer of concrete 4 should with dam crest ring field road 5 integral cast-in-situs and the concrete grade identical with its use.
Claims (2)
1. the anchor structure of a mine tailing storehouse initial stage dam crest anti-seepage geomembrane, it is characterized in that: the dam body inner slope one side excavation fluted (2) that needs antiseepage in the early stage on dam (1), inwall along groove (2) is equipped with anti-seepage geomembrane (3), be cast with landfill layer of concrete (4) on anti-seepage geomembrane (3), landfill layer of concrete (4) fills up whole groove (2).
2. the anchor structure of mine tailing according to claim 1 storehouse initial stage dam crest anti-seepage geomembrane, it is characterized in that: the dam crest of dam (1) is provided with dam crest ring field road (5) in the early stage, and dam crest ring field road (5) and landfill layer of concrete (4) are to use that the concrete of same numeral is integrated poured to be obtained.
