Flood draining and water returning in-common device used for tailing reservoir

Abstract

The invention discloses a flood draining and water returning in-common device used for a tailing reservoir. The flood draining and water returning in-common device comprises a headframe, a well seat, a flood draining pipe and a water returning pipe. The headframe is composed of vertical columns and ring beams. A plurality of flood draining inlets are defined by the vertical columns and the ring beams. Water returning vertical pipes are arranged in the vertical columns and provided with a plurality of water returning inlets. The well seat serves as a foundation of the headframe. A flood draining channel and a water returning channel which do not communicate with each other are formed in the well seat simultaneously. The flood draining pipe communicates with the flood draining channel arranged on the well seat. The headframe, the flood draining channel and the flood draining pipe constitute a communicating flood draining system. The water returning pipe communicates with the water returning channel formed in the well seat, and the water returning vertical pipes, the water returning channel and the water returning pipe constitute a communicating water returning system. According to the flood draining and water returning in-common device, a flood draining facility and a water returning facility are structurally combined and functionally independent to each other to achieve the functions of flood draining and water returning, the building engineering amount is little, the investment is low, the construction period is short, and operation and management are convenient.

Description

technical field [0001] The invention relates to the technical field of mine safety facilities, in particular to a flood discharge and backwater sharing device for tailings ponds. Background technique [0002] At present, the two sets of facilities for flood discharge and backwater of the tailings pond are independent of each other. The flood discharge facility of the tailings pond realizes flood discharge independently, and the backwater facility realizes backwater independently. Flood discharge from tailings ponds usually adopts a combination of drainage wells + backwater culverts or tunnels, or a combination of flood discharge chute + backwater culverts or tunnels, and backwater usually uses floating pumping stations, sub-dam pumping stations, and backwater wells Wait. [0003] However, the above-mentioned flood discharge and water return methods require the construction of two sets of facilities, which requires a large amount of construction work, high investment, and a ...

AI Technical Summary

Problems solved by technology

[0003] However, the above-mentioned flood discharge and water return methods require the construction of two sets of facilities, which requires a large amount of construction work, high investment, and a long construction period. It cannot make full use of the terrain height difference, wastes potential energy, and is inconvenient for operation and management.
