Description

Vertical seepage drainage device of tailing dam

Technical Field

The utility model relates to a technical field that the tailing storehouse was arranged and is oozed, concretely relates to vertical row of tailing dam oozes device.

Background

The safety factor of the accumulation of the initial dam and the later sub-dam of the tailing pond is one of the most important links for ensuring the safety of the tailing pond, and in recent accidents of the tailing pond, the tailing pond breaks due to poor water seepage effect of the tailing dam, so that villagers living in the downstream bear huge artificial debris flow disasters, and the life and property safety of the villagers is seriously harmed. In order to solve the problem that the tailing dam is untimely in water seepage and enhance the stability of the tailing dam, a novel water seepage device is arranged on a sub-dam of the initial dam, and the important link for ensuring the later safe operation of a tailing pond is achieved. The common tailing dam drainage in China is a horizontal drainage method, a drainage pipe is buried at the bottom of each stacking dam, water seeped out from the stacking dam is guided into a water collecting channel by using a filter pipe and the drainage pipe, the water collecting channel is guided to main channels on two sides of a dam body by using an open channel, and finally the water flows into a water return pipeline for secondary utilization. The blockage of the drainage pipe and the loss of drainage capacity often occur in the drainage process of the accumulation dam; the drainage is not uniform and the drainage effect is not good; the drainage and seepage pipe device is unreasonable, which causes insufficient drainage and seepage capability and directly affects the operation safety of the accumulation dam.

Disclosure of Invention

In order to overcome above-mentioned prior art's shortcoming, the utility model discloses an aim at provides a vertical row of tailing is piled up dam and is oozed device can make row's infiltration ability reinforcing, increases row and oozes the effect, improves the factor of safety of piling up the dam.

In order to achieve the above purpose, the utility model discloses the technical scheme who takes does:

the utility model provides a dam is piled up to tailing vertical row oozes device, including piling up dam 4, pile up and bury row in the dam 4 and ooze the person in charge 1 underground, arrange and ooze the person in charge 1 downward sloping, arrange and ooze the one end of being responsible for 1 and connect the water inlet of piling up the collector pipe 2 of placing on the dam 4 through first connecting pipe 3, arrange and ooze the middle part of being responsible for 1 and connect a plurality of vertical ascending row through a plurality of second connecting pipes 5 respectively and ooze branch pipe 6, arrange and ooze branch pipe 6 and arrange in the dry stand department of piling up dam 4 perpendicularly, arrange and ooze the outside parcel one deck nonwoven geotechnological cloth 6-1 of branch pipe 6, arrange and ooze the.

Furthermore, the top of the drainage and seepage branch pipe 6 is exposed out of the water surface, and the drainage and seepage branch pipe 6 is flush with the sub-dam height of the accumulation dam 4.

Furthermore, the top of the seepage drainage branch pipe 6 is respectively provided with a second plugging body 7.

Furthermore, the seepage drainage branch pipe 6 adopts a slotted hole seepage drainage pipe with the straight length of 50 mm-100 mm.

Furthermore, the main drainage pipe 1 is a steel pipe with the diameter of 100 mm-200 mm.

Furthermore, the water collecting pipe 2 adopts a PVC drain pipe with the diameter of 100 mm-200 mm.

Further, the first blocking body 8 and the second blocking body 7 are blocked by adopting non-woven geotextile and a white steel net.

Compared with the prior art, the utility model has the advantages of it is following:

1. the drainage and seepage branch pipes 6 are additionally arranged at the middle tail part of the drainage and seepage main pipe 1, so that the seepage area is enlarged, the drainage speed is accelerated, the drainage and seepage effect is more remarkable, the dry spreading length is powerfully ensured, and the safety factor of a tailing dam is improved.

2. Arrange drainage and seepage branch pipe 6 perpendicular in the dry stand department of tailing dam, drainage and seepage branch pipe 6's top surface of water that exposes, drainage and seepage branch pipe 6 and the high parallel and level of sub-dam of piling up dam 4 have replaced the horizontal drainage and seepage method in the past, the horizontal drainage and seepage method will be according to discharging the height and constantly adjusting plastics blind pipe height, can consume more manpower and materials, and the vertical drainage and seepage method can one step put in place, the later stage need not consume the manpower and adjust, and the infiltration rate is fast, and the effect is good, has more reduced labour's input.
