Problems solved by technology

Horizontal drainage pipe drainage is often limited by conditions and is difficult to implement. For example, it is difficult to drill holes in the rockfill when constructing radiation wells in front of rolling rockfill dams. In addition, it is difficult to overhaul and repair horizontal drainage pipes in tailings accumulation dams.
Mechanical pumps pump water, which is convenient for maintenance, but its operation requires manual management, which is inconvenient, and it is necessary to set up backup power generation equipment for use in case of power failure

Embodiment Construction

[0015] The present invention will be further described below in conjunction with embodiment and accompanying drawing.

[0016] With reference to accompanying drawing, present embodiment comprises siphon 2, pressurized well 4, and the water inlet end of described siphon 2 is provided with filter screen cover 1, and the top of described siphon 2 is provided with an opening, and described opening and the water inlet pipe of pressurized well 4 8 connected, the water inlet pipe 8 of the pressurized well 4 is provided with a water stop valve 5, the siphon pipe 2 is provided with an outlet water stop regulating valve 6, and the outlet of the siphon pipe 2 is provided with a U-shaped elbow 7.

[0017] The U-bend 7 can effectively prevent air from entering at the outlet, and keep the siphon effect continuous and the siphon flow stable.

[0018] When draining water, first close the outlet water stop regulating valve 6 of the siphon tube 2, open the water stop valve 5 of the pressurized ...

Abstract

The invention discloses a water-filling type siphon drainage device applicable to a radioactive well. The water-filling type siphon drainage device comprises a siphon pipe and a water pumping well, wherein a filter screen shield is arranged at a water inlet end of the siphon pipe; an opening is formed in a top of the siphon pipe and communicated with a water inlet pipe of the water pumping well; a water check valve is arranged on the water inlet pipe of the water pumping well; an outlet water check adjusting valve is arranged on the siphon pipe; and a U-shaped elbow pipe is arranged at an outlet of the siphon pipe. The water-filling type siphon drainage device applicable to the radioactive well is reliable to operate, convenient to maintain, safe to operate with less interference from external condition.

Description

technical field [0001] The invention relates to a pressure well type siphon drainage device for radiation wells. Background technique [0002] Tailings pool refers to the place where dams are built to intercept valley mouths or enclosures to store metal and non-metal mines for ore sorting and then discharge tailings. At present, there are more than 12,000 tailing ponds in my country, with a storage capacity of more than 10 billion tons. The safety problems of tailings ponds are prominent, especially in recent years, the frequent safety accidents of tailings ponds have caused great loss of life and property to the people, caused serious pollution to water resources and land resources, and affected construction Beautiful China, building a harmonious society, and realizing an environment-friendly development strategy. [0003] Tailings stacking techniques include upstream tailings damming, midline damming, and downstream damming. The safety facilities of tailings ponds genera...
