Description
Technical field
The present invention relates to a kind of radial pumped well formula siphon drainage device.
Background technology
Tailings Dam refer to build a dam interception the mouth of a valley or exclosure form carry out in order to store metal and nonmetal mine the place that ore sorts rear discharge mine tailing.At present, China's Tailings Dam quantity reaches more than 12000 seats, volume of cargo in storage more than 100 hundred million tons.The safety problem of Tailings Dam is given prominence to, particularly in recent years, the Safety of Tailings Dam accident taken place frequently, larger Loss of Life and property is caused to the people, serious pollution is caused to water resource, land resources, has 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 Tailing dam construction, centre-line damming, downstream method is built a dam, and the safety device of Tailings Dam are generally oozed system etc. formed by initial dam, fill dam, flood drainage system, row.It is closely bound up as the safety of important safety device and tailing dam that row oozes system, in tailing dam, the height of phreatic line is the key index determining tailing dam safety factor, by reducing the phreatic line height in tailing dam, the stability of dam body effectively can be improved.In engineering practice, the normal water seepage drainage facility adopted 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, throws filter pipe into increase the water yield of well in shaft bottom or the borehole wall by radiation direction, and general effect is better, develops from groundwater use engineering.Tailing dam is implemented radiation well array and oozes 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 horizontal drain pipe draining, mechanical pump draws water.Horizontal drain pipe draining is often not easily implemented by the restriction of condition, as radial of constructing before rolled rockfill dam, is difficult in enrockment internal drilling, 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, inconvenient, and needs to arrange power plant for emergency, 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, effectively can 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: a kind of radial pumped well formula siphon drainage device, 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 underground water is guided to ground instrument by one, is generally that cast iron is made, has a base, well head is delivery port, and pit shaft is thicker than aqueduct, and afterbody is the pressure handle connected together with the well heart, about have twenty or thirty centimetre long, ground water pressure draws up by the active force by diversion skin and the well heart.Have a piston above, have a valve below, this piston and valve are all one way valves, air is made up to walk and not walk downward, when piston is up walked, valve opening, can be extracted into cavity above and come by the air in pipe, 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 pressure, has been drawn up.
The present invention utilizes the operating principle of pumped well, is extracted out by the air in syphon, makes to be full of water in syphon, utilize siphonal siphon principle, is discharged by the water in radial.
Compared with prior art, the present invention has the following advantages: 1 operation and debugging, Long-Time Service; Syphon water yield can be regulated, to control height of water level in radial by regulating syphon outlet sealing control valve; Amount of seepage can be measured easily; According to the change of water percolating capacity, water valve can be adjusted or increases siphoning installation tricks; Maintenance is with install need not underground construction, and safety is high; Plant equipment need not be adopted to draw water, the electricity charge and cost of equipment and operational management cost can be saved.
Utilize the present invention, can construction level gutter or mechanical pump draw water again, low-carbon environment-friendly, estimate that each radial can be reduced investment outlay and be no less than 50,000 yuan, reliable, maintenance is convenient, handling safety, the interference by external condition is less, by the adjustment of siphon flow or increase siphon drainage device, can tackle the increase of radial seepage flow flow flexibly, 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.
Detailed description of the invention
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 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, diversion is added in pumped well 4, by pumped well 4, air in syphon 2 is extracted out, after pumped well 4 water outlet, in syphon 2, be full of water, close the water check valve 5 of pumped well 4, open the delivery port sealing control valve 6 of syphon 2, now syphon 2 starts draining, and water flow is descending, along with water level in radial 3 reduces, syphon 2 water flow tends towards stability gradually.
