Abstract
The present invention is by chamber, and at the bottom of the river tunnel, pilot shaft, and vertical shaft, pumping plant is formed.Chamber is positioned at stratum at the bottom of the river, and the chamber wall has the seepage flow hole, and sleeve pipe stretches to natural filter bed gravel bed at the bottom of the river by the radiation of seepage flow hole, and cannula tip is equipped with strainer tube, the strainer tube top closure, and the porose or seam of tube wall, strainer tube is arranged in gravel bed, bottom.The present invention is from the water table aquifer water intaking of bottom, riverbed, and water quality, the water yield are not directly influenced by river all, obtains stable, the cleaning of the water yield, and construction costs is cheap, can replace traditional water intake well.
Description
The present invention and water intaking, catchment or the device or the method for water distribution relevant, especially with the Weeping well with natural filter bed water intaking, it is relevant to supply water.
Traditional water intake well such as motor-pumped well, big well, infitration galleries, the width of cloth penetrate and or the like all destroy the filter bed structure inevitably, the filter bed upper and lower part is communicated with, all contaminations matter has enlarged and has polluted dizzy scope constantly to the deep migration, river bed water water quality is destroyed.Traditional influent well is arranged on ground, takies consumption ground, destroys ecotope, is easy to be subjected to flood, the destruction of disasters such as silt, and its service discharge also is subjected to having a strong impact on of low water season.
The purpose of this invention is to provide a kind of ecotope balance of not destroying, not influenced by disaster, it is stable to obtain the water yield, cleaning, the Weeping well with natural filter bed that construction costs is cheap.
As everyone knows: the sand gravel layer decapacitation of riverbed surface is filtered into the surface water of muddiness outside the good clear water of transparency, and goes to purify surface water quality by the series of physical chemical action.Facts have proved that topped mud film in the sandy gravel surface is to remove the desirable biological filter membrane that ammonia is denitrogenated.Mankind's activity is discharged into fluviatic all contaminations matter, and big portion is formed to pollute and swoons by natural filter bed absorption, and diffusion or disperse migration reaches balance again.Studies show that, contain all contaminations matter river by the dissolving of filter bed in filtration procedure, effects such as absorption have reduced the concentration of many toxic substances effectively.In natural filter bed middle and lower part, underground river bed water cleans.Utilize the film formed natural filter bed filteration of topped sandy gravel layer of rivers riverbed surface and mud, surface water is changed into underground river bed water, from the dried leak source of the water table aquifer base plate person of setting, constitute the current that leakage face forms big flow, infiltration stream is taken out ground design of the present invention just.
The present invention realizes like this.
The present invention is by chamber, with tunnel at the bottom of the river of chamber and pilot shaft connection, vertical shaft, pumping plant composition.Chamber is positioned at riverbed sub-surface at the bottom of the river.The chamber wall has the seepage flow hole, and sleeve pipe stretches to natural filter bed gravel bed at the bottom of the river by the radiation of seepage flow hole, and cannula tip is equipped with strainer tube, filters the porose or seam of tube wall.Strainer tube is arranged in gravel bed, bottom, promptly is provided with some leak sources at this place.
Can there be branch in tunnel of the present invention, and each branch's tunnel ends all has a chamber.
Some seepage flow hole on the chamber wall of the present invention is penetrated with different angles natural filter bed layer width of cloth at the bottom of the river, filters the hole on the tube wall or be sewn on gravel bed to form the leakage face of being made up of some leak sources.
The size of leakage face of the present invention is by the angle in seepage flow hole, and number is controlled the size and the position of leakage face, by natural filter bed structure, and the water table aquifer watery, the pollution of estuary degree, the distance of pollution, pollution substance, the dizzy migratory direction of pollution require parameter decisions such as the water yield.
The present invention obtains wandering water from the river bed water of natural filter bed filtering cleaning, saved the expense of filtration treatment, and is with low cost.The present invention is easy to obtain a large amount of river bed waters from " natural filter bed ", can reach the daily output 1-5 myriametre or the bigger water yield, and this is that conventional intake technology is difficult to realize.The present invention has more significance for obtaining than big yield from aquitard.The water yield of the present invention is calculated the relation that adopts hydrostaticpressure and the water yield, the theory of the relation of the water level elevation and the water yield, derives and influences the coefficient of water yield equation, can design the amount of obtaining of evaluation water very reliably.Construction technology of the present invention also is very sophisticated, and construction costs is low.That the present invention is arranged on is underground, account for the arable land less, is not subjected to the influence of flood, silt, mountain region disaster, keeps the ecotope balance, has tangible economic results in society.
Following is accompanying drawing of the present invention
Fig. 1 is embodiments of the invention 1 structural maps
Fig. 2 implements example 2 figure.
Fig. 3 is that the A of Fig. 2 is to view.
Following is embodiments of the invention:
Embodiment 1:
Chamber 1 of the present invention is positioned at the bottom of the river, and chamber has supporting steelframe 2.The chamber wall has seepage flow hole 3, creeps into from seepage flow hole 3 to river basal conglomerate layer.When creeping into, sleeve pipe 4 and strainer 5 need not rotate synchronously with infiltrating in the discharge orifice 3.Special-purpose drill bit and hole enlarger outwards turn round in the drilling process, get out one than strainer 5 big other holes of level, when reaching required, drilling tool is counter to be bored, hole enlarger is turned back to its minimum diameter inward, and drill bit can withdraw from by the strainer of staying in the hole 5, and strainer plays the guard aperture effect simultaneously.Use a taper plug 6 then, plug is bumped in the gravel bed, seal filter end, prevent that silt from entering the seepage flow hole, make underground latent water reach the clean purpose of water sand removal through double filtration with high jarring method.Above technology is used to contain the natural filter bed of big erratic block and perpendicular hard dog's-head formation.The seepage flow hole of the sand gravel stratum that particle is less adopts strainer 5 that down will seal the end to hit or hit the method for creeping into and follows into gravel bed synchronously at the end with pushing up by the seepage flow hole on the basement rock.Chamber 1 is communicated with by tunnel at the bottom of the river 8 with vertical shaft 7.There is headrace 17 in the tunnel at the bottom of the river.Vertical shaft is pilot shaft 9 down.Hoistway wall adopts the pre-supporting of weldless steel tube support, the full supporting of reinforced concrete well letter.Tunnel two walls adopt that precast concrete is brick to be protected at the bottom of the river, and Ji Ding is the full supporting of cast-in-situ steel reinforced concrete.There is ventilation hole 10 in the tunnel at the bottom of the river.Vertical shaft has pump house 15 and deep well submerged pump 16.Present embodiment has the width of cloth to penetrate each eight of seepage flow hole and supporting sleeve pipe, strainers, and elevation angle minimum is 5 °, be to the maximum 18 ° day water yield be 25238 tons.
Embodiment 2:
Basic structure is identical with embodiment 1.Just there is Zhi Suidao 12 in tunnel 11 at the bottom of the river.The tunnel end has chamber 13,14.Chamber is positioned at the bottom of the river.9 seepage flow holes that each the oriented river of chamber wall basal conglomerate layer width of cloth is penetrated, sleeve pipe in the hole and strainer structure are with embodiment 1.
