A water drainage channel of the tailing dam further can convey oozed sewage from a tailing to a specified area along a specified channel for treatment without polluting the environment, thereby being suitable for popularization and implement. The tailing dam is fixed by a water-blocking device in a tailing fluid period, a tailing layer is formed by water drainage, a dam body is formed by sequentially overlapping, and therefore, a fixed angle (identical with a repose angle) is formed after the dam body tailing is dried, the tailing dam can be formed naturally without depending on the water blocking device and stress, and a simple tailing dam structure is achieved. The tailing dam is easy to construct, short in construction period and stable in structure.

Description

Tailing dam

Technical field

The utility model relates to the tailing dam in a kind of hydrotechnics field, particularly relates to a kind of tailing dam.

Background technology

Tailing dam is the dam formula building that utilizes mud ore deposit quarrel (mine tailing) or local material behind the hydraulic beneficiation to build up, and tailing dam need be considered moisture fluid mine tailing seeped water to handle when building to form fixedly dam body.Existing tailing dam utilizes the natural terrain of fluctuating to construct usually and forms, and building the dam is to need to consider dash infiltration structure, and charging aperture, discharge gate and clarified solution retrieval system, causes complex structure, and the difficulty of construction large period is long, and cost is high.

Summary of the invention

In order to overcome the deficiency that prior art exists, the utility model provides a kind of tailing dam special-purpose baffle device for water tailing dam of constructing.

Technical scheme: the special-purpose baffle device for water of a kind of tailing dam; Comprise the truss-like braced structures; This truss-like braced structures lower end is fixed on the concrete bearing platform, and fixing watertight shutter on this truss-like braced structures is distributed with drain hole on each watertight shutter; Be respectively arranged with rhone on the vertical pillar of each crossbeam of lattice supporting framework and both sides, the transverse row tank is communicated with water treatment system after being summarized in the vertical drainage groove.

Said trussed construction is the combining structure of a plurality of minutes truss, each minute truss each pillar suit and fixing successively.

A kind of tailing dam; Comprise mine tailing and geomembrane; Formed by several layers mine tailing layer stack combinations successively, the upstream face angle of inclination of this combining structure is consistent with the natural angle of repose of use geomembrane, and wherein said mine tailing layer is enclosed with geomembrane at least on three faces of upper and lower and upstream face.

Be provided with vertical well at tailing dam near upstream face one side, the different elevation position distribution of the borehole wall have water inlet, and the shaft bottom is communicated with at the bottom of the dam or dam outboard row aquaporin.

Impervious barrier is set at the bottom of the riverbed.

The beneficial effect of the utility model: the tailing dam of the utility model is through baffle device for water it to be fixed period at the mine tailing fluid; Draining forms the mine tailing layer; Stack forms dam body successively; Because the angle of inclination of baffle device for water adapts with the angle of repose of mine tailing dry state,, can not rely on baffle device for water and get final product the nature moulding and the power that do not suffer oppression so treat the fixed angle that forms after the dam body mine tailing drying.Thereby realized simple tailing dam structure, construction easily, short construction period, and Stability Analysis of Structures.

The tailing dam baffle device for water of the utility model is made up of the watertight shutter of main body frame and each layer; The installation that can successively superpose according to actual needs of every layer of watertight shutter; Simple in structure, easy to use, its drainage channel can be transported to the appointed area along special modality with the sewage that oozes out in the mine tailing again and handle; Free from environmental pollution, be fit to promotion and implementation.

The specific embodiment

Embodiment one: referring to Fig. 1-Fig. 7; A kind of tailing dam special-purpose baffle device for water of constructing comprises the truss-like braced structures, and this truss-like braced structures lower end is fixed on the concrete bearing platform 35; Fixing watertight shutter 5 on this truss-like braced structures; Be distributed with drain hole on each watertight shutter 5, each crossbeam 34 inboard of lattice supporting framework are provided with rhone, are respectively arranged with rhone 32 on the vertical pillar 31 in both sides; The transverse row tank is communicated with total rhone 36 again after being summarized in the vertical drainage groove, and total rhone 36 is communicated with water treatment system.

Trussed construction is designed to the combining structure of a plurality of minutes truss, each minute truss each pillar suit and fixing successively, also can fix respectively.

When present embodiment is implemented, stop gauge is set, the inclination angle of stop gauge is set according to the angle of repose of use mine tailing dry state in back side one side; Baffle device for water comprises the truss-like braced structures; The baffle device for water lower end is fixed on the concrete bearing platform; Fixing watertight shutter on this truss-like braced structures; Be distributed with drain hole on each watertight shutter, be respectively arranged with rhone on the vertical pillar of each crossbeam of lattice supporting framework and both sides, the transverse row tank gather with the vertical drainage groove after be communicated with water treatment system.Impervious barrier at first is set at the bottom of the riverbed.On impervious barrier, lay one deck geomembrane again, geomembrane is positioned at back side one end, and to leave surplus subsequent use.

Discharging mine tailing fluid on geomembrane, under baffle effect, the mine tailing fluid forms one deck mine tailing layer after being stopped draining.

With remaining geomembrane along inflection on the in type mine tailing course once, form the overlapping geomembrane that is positioned at the tailing dam upside, geomembrane is positioned at back side one end, and to leave surplus subsequent use.

On above-mentioned mine tailing layer and overlapping geomembrane, continue discharging mine tailing fluid, under baffle effect, the mine tailing fluid forms second layer mine tailing layer after being stopped draining.

Repeat above step successively, meet the tailing dam main body of height of dam requirement until formation; According to the mine tailing layer height, the height that increases stop gauge gradually perhaps increases the watertight shutter of stop gauge gradually.

Behind the tailing dam main body dryness finalization, cancel stop gauge, form the dam body of forming by tailing dam fully.

Vertically dig a well near upstream face one side at tailing dam, the different elevation position distribution of the borehole wall have water inlet, and the shaft bottom is communicated with at the bottom of the dam or dam outboard row aquaporin.According to the mine tailing composition, if mine tailing has noxious material, need discharge at the bottom of the dam or dam outboard row aquaporin is that water is handled.
