In the operation process, the ship body is moved according to the requirements of the water level in the reservoir and the clarification distance; the other is water taking from backwater structures, water is taken from structures such as backwater wells built in the storeroom, backwater chutes and the like, and the cover plate of the backwater well (or the backwater chute) needs to be plugged or dismantled according to water level change and water quality requirements by adopting the mode for taking water.

The adoption of a storage boat type pump station for water taking has higher capital construction cost. In addition to the hull costs, the costs of the pontoon between the hull and the shore (transport, maintenance, etc. use) are also taken into account, since this type requires a longer pontoon to be arranged.

In conclusion, the water taking method in the tailing pond according to the embodiment of the second aspect of the invention has the advantages of low capital cost, simple operation and maintenance and small safety risk.

According to one embodiment of the second aspect of the present invention, the first through nth stage ramps 1 are all the same height. It can be understood that, the first-stage ramp 1 to the nth-stage ramp 1 have the same height h from the bottom end to the top end of each stage ramp 1, so that the length of the water inlet pipe 3 does not need to be changed when the self-priming water pump 2, the water inlet pipe 3 and the water outlet pipe 4 are shifted step by step, the cost is reduced, and the water taking efficiency is improved.

According to an embodiment of the second aspect of the present invention, the tops of the first-stage ramp 1 to the nth-stage ramp 1 are all horizontal planes or all top slopes in the length direction of the dam section bank slope 5 of the tailings pond or the bank slope in the pond. It can be understood that the tops of the first-stage slope ramp 1 to the nth-stage slope ramp 1 can be horizontal planes or top slopes, when the tops of the slope ramps 1 to the nth-stage slope ramp 1 are top slopes, the self-priming water pump 2 can move on the top slopes along the length direction of the dam section bank slope 5 of the tailing pond or the bank slope in the tailing pond along with the rise of the water level of the upper clear water body 6 in the tailing pond, and water taking is convenient.
