Abstract
The utility model discloses a device for relieving tailings pond flood drainage pressure. The device comprises a tailings pond, a flood-control dam and flow drainage pipes. The flood-control dam is arranged in an upstream area of the tailings pond, the flow drainage pipes are arranged in a dam body of the flood-control dam, and axes of the flow drainage pipes are perpendicular to a lateral axis of the dam body of the flood-control dam. The device for relieving the tailings pond flood drainage pressure has the advantages that the flood-control dam and the flow drainage pipes together play the roles of 'flood interception', 'flood detention' and 'peak-load regulation', peak flood flow of flood entering the tailings pond is greatly reduced, and therefore the flood drainage pressure of a flood drainage system in the tailings pond is relieved, accordingly, the size of a flow drainage cross section of the flood drainage system can be reduced, project cost of the flood drainage system is reduced to a large degree, and safety reliability of the flood drainage system is improved. The flood-control dam can also intercept quicksand and rolling stones carried by upstream flood and prevent the quicksand and the rolling stones from depositing to occupy valuable flood regulation storage capacity of the tailings pond and blocking flood drainage flow drainage ports, and therefore safe flood drainage capacity of the tailings pond is ensured. The device for relieving the tailings pond flood drainage pressure is a good water and soil loss prevention and cure project measure.
Description
Technical field
The utility model relates to the Mine Safety Technology field, especially a kind of alleviation Tailings Dam pressure apparatus that drains off floodwaters.
Background technology
Tailings Dam is the association of the various structure of the mine tailing that produces behind the safe storage mine ore dressing.The security and stability of Tailings Dam depends primarily on two aspects: the firstth, and the security and stability of tailing dam; The secondth, the security and stability of flood drainage system.According to statistics, China's nonferrous metal mine causes 50% of the whole Tailings Dam accident that almost accounts for of disaster because of the flood drainage system accident.Therefore the reliable flood drainage system of science, safety are set, and to get rid of swimmingly the flood of Tailings Dam most important for the security and stability of Tailings Dam.
In view of having stored these particular job characteristics of a large amount of mine tailings in the Tailings Dam, follow following principle during the design of the flood drainage system of Tailings Dam as far as possible: the first, as far as possible by cut big vast the measure such as flood diversion reduce the water yield (W of flood into reservoir
p); The second, take measures to reduce the peak flood flow (Q of flood into reservoir
m), prolong under the flood and let out the time, alleviate the pressure of flood discharge water under the Tailings Dam flood drainage system, i.e. " peak regulation ".
The utility model belongs to the second measure, can reduce the peak flood flow (Q of flood into reservoir
m), prolong under the flood and let out the time, alleviate the pressure of Tailings Dam flood drainage system, thereby improve the safety of Tailings Dam flood drainage system, ensure the security and stability of Tailings Dam.
Summary of the invention
The purpose of this utility model is to provide a kind of alleviation Tailings Dam pressure apparatus that drains off floodwaters, and this device can be alleviated the pressure of Tailings Dam flood drainage system, reduces the flood drainage system cross dimension, thereby improves the safety of flood drainage system, ensures the safety and stability of Tailings Dam.
The technical solution of the utility model is: a kind of alleviation Tailings Dam pressure apparatus that drains off floodwaters, and this device comprises: Tailings Dam, regulating dam, leak-off pipe; Regulating dam is arranged in the Tailings Dam upstream region, and leak-off pipe is arranged in the regulating dam dam body, and leak-off pipe tubular axis line is perpendicular to the transversal line of regulating dam dam body.Regulating dam is waterproof dam type.The influent stream pipe end of leak-off pipe arranges flange.Movable blind plate is set, with control opening and closing flange in the flange.
The utility model has the advantage of: regulating dam and leak-off pipe play " cutting flood ", " flood detention ", " peak regulation " effect jointly, prolong lasting of letting out under the flood of upstream, greatly reduce the peak flood flow that enters the Tailings Dam flood, thereby extenuated the pressure that drains off floodwaters of flood drainage system in the Tailings Dam, and can reduce the earial drainage cross dimension of flood drainage system thereupon, not only reduced flood drainage system by on cover mine tailing load weight and the risk of damaging, and reduced the construction costs of flood drainage system largely, improved the safety reliability of flood drainage system.Regulating dam can also be tackled quicksand, the Rolling Stone that the upstream flood carries, and prevents that the alluvial of quicksand, Rolling Stone from taking the reservoir capacity for flood control of Tailings Dam preciousness, and prevents its obstruction relief port of drainning off floodwaters, and ensures the safe flood discharge capacity of Tailings Dam.It is a kind of preferably prevention and control of soil erosion engineering measure.

Fig. 2 is the utility model A-A sectional view;
Fig. 3 is the utility model B-B sectional view.
The specific embodiment
When flood is come in Tailings Dam 1 upstream, regulating dam 2 with flood all or major part retain in the flood retention storehouse, flood finally enters in the Tailings Dam 1 gradually by leak-off pipe 3, flange 5 and the blind plate 6 that can arrange by adjusting leak-off pipe 3 influent stream pipe ends 4, come controlled discharge pipe 3 to be in opening or closed state: can be according to the rising of tailings face, progressively open flange 5 and the blind plate 6 of leak-off pipe 3 influent stream pipe ends 4 settings of each elevation, by calculating in advance the discharge capacity of all leak-off pipe 3 of this layer, reach the flow of the lower flood discharge water of control, reduce the peak flood flow Qm that enters Tailings Dam 1 flood thereby play, prolong under the flood and let out time t, alleviate the pressure of Tailings Dam 1 flood drainage system, thereby improve the degree of safety of Tailings Dam 1.The great flood that surpasses design standard is drained from flood spillway 7 overflows of regulating dam side.
The quantity of leak-off pipe 3 and caliber are to need the slow flood discharge of letting out of interception to calculate configuration, general recommend adoption high density polyethylene (HDPE) DN300HDPE water service pipe, SDR17 type, PE80 level according to regulating dam 2; Can arrange 1～n root in same elevation horizontal direction, the level interval between the leak-off pipe 3 of same elevation should not be less than 5.0m; Arrange along with the continuous rising of Tailings Dam 1 interior tailings face that in vertical direction pre-plugged is in dam body when building regulating dam, the pipe end shutoff advises being the blossom type interlaced arrangement.Suggestion 5% falls in leak-off pipe 3 longitudinal gradients.When tailings face elevation is lower than leak-off pipe 3 outlet axis elevations and is not more than 0.5m, need to adopt blind plate 6 to insert flanges 5 with sealing leak-off pipe 3.When the tailings face rises, when flooding lower one deck leak-off pipe 3, leak-off pipe pipe end flange 5 and the blind plate 6 of last layer are removed, and are enabled new leak-off pipe 3, by this principle until go up a drainage flow pipe 3 most and enable.
Regulating dam 2 is waterproof dam type.The high density polyethylene (HDPE) material is adopted in blind plate 6 suggestions.
In order to improve the water conservation ability of regulating dam as far as possible, regulating dam 2 should be in " empty storehouse " state in the non-flood season, with the flood of retaining in the storehouse emptying of trying one's best, the leak-off pipe 3 double effects of playing " blow-down pipe " this moment, namely by leak-off pipe 3 with the flood of retaining in the storehouse emptying of trying one's best.And need periodic cleaning to transport quicksand, the Rolling Stone that deposits before the regulating dam.
