Abstract
The invention discloses an efficient and vertical drainage device of a tailing pond. The efficient and vertical drainage device comprises a drainage pipe (1) and connection pipes (2), wherein the drainage pipe (1) is vertically arranged in the tailing pond and is connected with a concealed drainage pipe and a drainage chute through the connection pipes (2) or is directly led out of the tailing pond, the drainage pipe (1) is composed of a pipe body (3), filter cloth (4) and a fixing net (5), the center of the pipe body (3) is provided with a plurality of through holes (31), and the filter cloth (4) covers the outer circumference of the pipe body (3). According to the drainage device, the drainage pipe with the through holes in the inner wall and the filter cloth covering the outside of the pipe body is vertically arranged in the tailing pond, so that tailings can achieve funnel-type drainage along the drainage pipe at the angle of 45 degrees, the drainage area gradually becomes large along with accumulation of the tailings, the closer the tailings are to the drainage pipe, the better the effect is, a seepage line is effectively lowered in the vertical direction, and safety of the tailing pond is guaranteed. Compared with a traditional horizontal drainage pipe, the drainage pipe of the drainage device is resistant to compression, not prone to being bent, capable of being used as a horizontal drainage pipe and also capable of being matched with the horizontal drainage pipe in use.
Description
Technical field
The invention belongs to mine engineering technical field, be specifically related to that a kind of working stability is reliable, row is oozed the in line device that oozes of Tailings Dam high-efficient vertical that efficiency is high, running cost is low.
Background technology
At the dam body of China's tailings reservoir preliminary dam, be that the native clitter that do not waited by water permeability power is built and formed.The heap mode of building on the sub-dam of Tailings Dam adopts upstream stacked more.The tailings filter structure body venting mainly forming by accumulation due to this pattern immerses the percolating water of inside, storehouse, therefore once drainage body structure is difficult to form or destroyed because of some reason (as too much in fine-graded placer deposits interburden layer in storehouse etc.), the phreatic line of inside, storehouse will be raised, percolating water just may be overflowed and form swamp land at dam facing from dam slope, even causes piping.Although inundating the dam by flood, crevasse, dam break, flood drainage system inefficacy, slope instability, seepage flow are out of control, earthquake liquefaction etc., be upper reaches method tailing dam mainly cause dangerous factor, wherein approximately have 1/4 dam-break accident to be controlled to lose efficacy by seepage flow and cause.Obviously, this working condition of Tailings Dam is unfavorable for himself stability and safety, does not also allow occur and must be prevented.Therefore, Tailings Dam should be controlled the height of phreatic line to guarantee seepage failure not to occur, and guarantees the safe operation of Tailings Dam.
Tailings Dam, in order to reduce dam seepage line, reduces dam body osmotic pressure, improves the kinetic stability of upstream type tailing dam, generally at tailing dam, fills in process, and engineering services are oozed in the row of layout.Common water seepage drainage facility has: deep-cut french drain, siphonic water-collecting well, light well point, open caisson, radial and vertical horizontal combined seeping water discharging etc.Water seepage drainage facility can significantly reduce phreatic line position, is conducive to prevent that dam slope seepage erosion, earthquake liquefaction, assurance dam body are stable.Reasonably arrange that water seepage drainage facility is the key that guarantees Tailings Dam Seepage Safety, the phreatic line of controlling Tailings Dam is more low safer, and it is the drainage pipe of laying the 2% left and right gradient that traditional row is oozed device, is connected to the gutter outside dam.Percolating water is discharged to outside dam body after horizontal drain pipe enters the collecting gutter on sub-dam again, and the phreatic line of Tailings Dam is controlled at below safe scope.The general row that one group of level is installed when 4 meters of left and right, tailings pile dam is oozed device, and this device is that the water below drainage pipe arrange, and row ooze device above too high water only have small part can be discharged in pipe, its sphere of action is subject to certain restrictions.And traditional horizontal seepage pipe is flexible, not resistance to compression, can only horizontal arrangement.
Summary of the invention
The object of the present invention is to provide that a kind of working stability is reliable, row is oozed the in line device that oozes of Tailings Dam high-efficient vertical that efficiency is high, running cost is low.
The object of the present invention is achieved like this, comprise drainage pipe, tube connector, described drainage pipe is vertically arranged in Tailings Dam and by tube connector, drainage chutes and connects or directly draw outside storehouse, described drainage pipe is provided with the body of a plurality of through holes by circumference, and the filter cloth and the fixed network formation that cover body excircle.
The drainage pipe that the present invention arranges through hole and covers filter cloth outward by inwall is vertically set in Tailings Dam, and be connected with Tailings Dam closed drain or drainage chutes by level or inclined connecting pipe, the funneling row who makes the vertical drainage pipe arranging in mine tailing formation edge be 45 ° is oozed structure, under the effect of gravity, along with the accumulation of mine tailing, making the row of drainage pipe ooze area progressively increases, better the closer to gutter water seepage drainage effect, thereby in the vertical direction effectively reduces the phreatic line of Tailings Dam, guarantees Safety of Tailings Dam.By drainage pipe through hole is arranged in excircle annular recess and/or axial notch and/or helical groove, thereby can increase drainage pipe excircle water conservancy diversion area, be conducive to arrange and ooze fast and efficiently; By in tube connector one end, draw-out device being set, drainage pipe upper end closed or inspiratory capacity by-pass cock is set, can control when needed and in drainage pipe, form negative pressure, thereby strengthen water seepage drainage effect; Or water section diameter is less than draining section diameter and/or tube connector arranges flow control valve for entering of being connected with drainage pipe at tube connector, also can not need to consume in the situation of the energy, make tube connector form siphonic effect, thereby make drainage pipe form negative pressure, strengthen water seepage drainage effect.
