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
The present invention relates to a kind of radial pumped well formula siphon drainage device.
Background technology
The place of carrying out ore and sort rear discharge mine tailing in order to store metal and nonmetal mine that Tailings Dam refers to that build a dam the interception mouth of a valley or exclosure form.At present, nearly more than 12000 of China's Tailings Dam quantity, more than 100 hundred million tons of volume of cargo in storages.The safety problem of Tailings Dam is outstanding, particularly in recent years, the Safety of Tailings Dam accident taking place frequently, to the people, caused larger Loss of Life and property, water resource, land resources have been caused to serious pollution, had influence on and build beautiful China, build a harmonious society, realize environmentally friendly development strategy.
The heap building technology of mine tailing has upper reaches method mine tailing to build a dam, middle collimation method is built a dam, downstream method is built a dam, and the safety device of Tailings Dam generally ooze system etc. by initial dam, fill dam, flood drainage system, row and form.It is closely bound up as the safety of important safety device and tailing dam that row is oozed system, in tailing dam, the height of phreatic line is the key index of determining tailing dam safety factor, by reducing the phreatic line height in tailing dam, can effectively improve the stability of dam body.In engineering practice, the normal water seepage drainage facility adopting has the forms such as drainage pipe, radial, water seepage drainage mattress pad, vertical-horizontal combined seeping water discharging.
Radial is a kind of large well with radiation transverse tube, in shaft bottom or the borehole wall by radiation direction, throw filter pipe into increase the water yield of well, general effect is better, from groundwater use engineering, develops.On tailing dam, implement radiation well array and ooze the phreatic line height that can effectively reduce in tailing dam, water yield can be several times as much as horizontal seepage pipe, at present, has been widely used in Safety of Tailings Dam and has administered in stabilization works.
The draining of radial has various ways, mainly comprises that horizontal drain pipe draining, mechanical pump draw water.Horizontal drain pipe draining is often subject to the restriction of condition to be difficult for implementing, and as the radial of constructing before rolled rockfill dam, is difficult in enrockment internal drilling, and construction level gutter in this external tailing dam, overhauls more difficult.Mechanical pump draws water, and be convenient to maintenance, but its operation needs labor management, inconvenience, and power plant for emergency need to be set, to use under powering-off state.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of easy and simple to handle, reliable, can effectively discharge the radial pumped well formula siphon drainage device of percolating water in radial.
The technical solution adopted for the present invention to solve the technical problems is: pumped well formula siphon drainage device for a kind of radial, comprise syphon, pumped well, described siphonal water inlet end is provided with filtering screen, described siphonal top is provided with an opening, described opening is communicated with the water inlet pipe of pumped well, the water inlet pipe of described pumped well is provided with water check valve, and described syphon is provided with outlet sealing control valve, and siphonal exit is provided with U-shaped bend pipe.
Described pumped well is that one is guided to ground instrument by underground water, is generally that cast iron is made, and has a base, well head is delivery port, and pit shaft is thicker than aqueduct, and afterbody is the pressure handle connecting together with the well heart, approximately there is twenty or thirty centimetre long, by the active force of diversion skin and the well heart, ground water pressure is drawn up.Have a piston above, have a valve below, this piston and valve are all one way valves, air is up walked and do not walked downward, when piston is up walked, valve opening, can be extracted into the air in pipe cavity above and come, when piston walks downward, valve closing, air comes up from piston limit, and so circulation will be evacuated in pipe below, water just, under atmospheric effect, has been drawn up.
The present invention utilizes the operating principle of pumped well, and the air in syphon is extracted out, makes to be full of water in syphon, utilizes siphonal siphon principle, and the water in radial is discharged.
Compared with prior art, the present invention has the following advantages: 1 operation and debugging, use for a long time; Can be by regulating syphon outlet sealing control valve to regulate syphon water yield, to control height of water level in radial; Can measure easily amount of seepage; Can be according to the variation of water percolating capacity, adjust water valve or increase siphoning installation tricks; Maintenance is with install needn't underground construction, safe; Needn't adopt plant equipment to draw water, can save the electricity charge and cost of equipment and operational management cost.
Utilize the present invention, construction level gutter or mechanical pump draw water again, low-carbon environment-friendly, estimating that each radial can be reduced investment outlay is no less than 50,000 yuan, reliable, maintenance facilitates, handling safety, is subject to the interference of external condition less, by the adjusting to siphon flow or increase siphon drainage device, can tackle flexibly the increase of radial seepage flow flow, be that other drainage patterns are incomparable.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention-radial pumped well formula siphon drainage device;
Fig. 2 is pumped well structure enlarged diagram embodiment illustrated in fig. 1;
Fig. 3 is the U-shaped bend pipe structure enlarged diagram in syphon exit embodiment illustrated in fig. 1.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the invention will be further described.
With reference to accompanying drawing, the present embodiment comprises syphon 2, pumped well 4, the water inlet end of described syphon 2 is provided with filtering screen 1, the top of described syphon 2 is provided with an opening, described opening is communicated with the water inlet pipe 8 of pumped well 4, the water inlet pipe 8 of described pumped well 4 is provided with water check valve 5, and described syphon 2 is provided with outlet sealing control valve 6, and the exit of syphon 2 is provided with U-shaped bend pipe 7.
Described U-shaped bend pipe 7 can effectively prevent that exit from entering air, keeps siphonage continuously and syphon stability of flow.
During draining, first close the outlet sealing control valve 6 of syphon 2, open the water check valve 5 of pumped well 4, to the interior interpolation diversion of pumped well 4, by pumped well 4, interior syphon 2 air is extracted out, after pumped well 4 water outlets, in syphon 2, be full of water, close the water check valve 5 of pumped well 4, the delivery port sealing control valve 6 of opening syphon 2, now syphon 2 starts draining, and water flow is descending, along with the interior water level of radial 3 reduces, syphon 2 water flows tend towards stability gradually.
