Summary of the invention
The purpose of this utility model is exactly at the problems referred to above, aims to provide a kind of simple in structurely, and materials are gathered materials on the spot, and can guarantee that safety of dam body is stable, the mine tailing storehouse of realizing increasing significantly dilatation.
For this reason, the technical solution taked of the utility model is:
A kind of dilatation tailing storehouse of increasing is to set up to increase the dilatation dam on the basis that original " upstream formula " mine tailing is built a dam, and is equipped with on the dam foundation of increasing the dilatation dam vertically and transverse row is oozed french drain, has the retaining dam along the toe place of increasing the dilatation dam.
Described retaining dam system adopts the building stones heap to build and forms, and retaining is established the infiltration body in the dam, makes dam body form the drainage rock-fill dam structure.
The described dilatation dam of increasing is to be piled up by the coarse fraction sand setting mine tailing that separates in the mine tailing to form.
The beneficial effects of the utility model are:
The utility model is built a dam with original " upstream formula " mine tailing and is the basis, utilize the discarded for many years mine tailing of piling up, through the sand setting mine tailing of resulting separation original mine tailing is built a dam to pile up and increase thickening, when reinforcing tailing dam, enlarging the mine tailing storage capacity, realized twice laid, both greatly reduce engineering cost, reduced the mine tailing storage capacity again.
Simultaneously, make full use of the physico mechanical characteristic of mine tailing, the geography in mine tailing storehouse, orographic condition and unemployed space, and carry out the mine tailing storehouse in conjunction with the engineering present situation in tailing storehouse and increase that drainage is reinforced in dilatation, base slope and ground row is oozed processing, not only greatly prolonged the length of service in mine tailing storehouse, avoid the investment and the occupation of land in newly-built mine tailing storehouse, and have that dilatation amount in mine tailing storehouse is big, the tailing dam security and stability is good, engineering construction is convenient, gather materials on the spot and reduce expenses and many advantages such as the maintenance management expense is low, have very big economic benefit and remarkable social benefit.
Description of drawings
Accompanying drawing is for increasing dilatation tailing storehouse generalized section.
Among the figure: mine tailing is built a dam 1, is increased dilatation dam 2, retaining dam 3, retaining dam infiltration body 4, row ooze french drain 5.
The specific embodiment
Below, in conjunction with the accompanying drawings the utility model is further described.
By accompanying drawing as seen, the utility model mainly by mine tailing build a dam 1, increase dilatation dam 2, retaining dam 3 and row ooze french drain 5 and formed.Its unitary construction is to build a dam at original " upstream formula " tailing to pile up the coarse fraction sand setting mine tailing that separates with the side from mine tailing above 1, forms and increases dilatation dam 2, thereby make whole mine tailing dam body increase thickening, enlarges the storage ore deposit capacity in mine tailing storehouse.
In order to prevent to increase the coarse fraction sand setting mine tailing flow further downstream that dilatation dam 2 is piled up, promptly with the building stones block retaining dam 3 is arranged one at the lower margin of increasing dilatation dam 2 along the whole toe of increasing dilatation dam 2, retaining 3 inside, dam are provided with a plurality of infiltration bodies, make the retaining dam body form a drainage rock-fill dam structure, to drain the moisture in the coarse fraction sand setting mine tailing, avoid coarse fraction sand setting mine tailing owing to the landslide phenomenon too much appears in water content, improve the stability of increasing dilatation dam 2 dam bodys.Coarse fraction sand setting mine tailing is to adopt hydrocyclone that discarded mine tailing is separated to obtain after handling with classification, and the overflow mine tailing that obtains is simultaneously handled by the mine tailing of storing.
In addition, be equipped with vertical transverse row that reaches and ooze french drain 5 on the ground of increasing dilatation dam 2, its effect also is the water seepage that reduces and discharge whole dam body, improves the intensity of dam body, the service life in prolongation mine tailing storehouse.
