Description

A kind of water intaking gallery of gravity flow groundwater reservoir
Technical field
The present invention relates to draw in the hydraulic engineering phreatic method or device, particularly a kind of arid biogeographic zone that is suitable for covers the water intaking gallery that river valley area and diving overflow the gravity flow groundwater reservoir of band place building deeply.
Background technology
U.S.'s 21 century water resource strategic research achievement proposes, and groundwater reservoir is the main means of 21 century water resource regulation and control.According to studies show that both at home and abroad, the Nature reaches 12,000,000,000,000 m by the water yield of underground circulation for many years 3, be equivalent to 30% of surface flow total amount, and the at present human water yield of regulating by face of land reservoir 20,000 hundred million m only 3, this shows that underground have at least 6 times in the face of land of the being equivalent to reservoir storage capacity that catchments to develop for people.For groundwater reservoir, external formulation commonly used is " aquifer stores and back production (ASR-aquiferstorage and recovery) ", the ASR construction plan that the U.S. is implementing, to in July, 2002, the ASR system that has moved has 56, the system of the ASR that builds up is nearly more than 100, Florida downstate only, 26 ASR engineerings have been built the Gulf bank, 330 mouthfuls of ASR wells are arranged approximately, Sweden, Holland, Germany, Australia, Japan, states such as Iran are all implementing the ASR construction plan, to solve the shortage and the problem of regulating and storing of water resource, Sweden, the artificial recharge aquifer engineering of Holland and Germany, shared share reaches 20% respectively in its total water supply at present, 15% and 10%.Groundwater reservoir has remarkable advantages at technology, environment and economic aspect: the simple investment of groundwater reservoir engineering structures is less, and the surface evaporation amount is few relatively, does not have the dam break disaster, long service life is dispatched, is managed simply, and storage capacity sediment deposition problem is outstanding, do not account for the soil, need not migrate; The groundwater reservoir storage capacity can play the rich withered regulating action for many years of adopting of holding greatly, and it can not trigger the landslide avalanche on slope, bank, storehouse, does not destroy the ecological environment of straddling fish stocks yet; The practice of home and abroad shows that the groundwater reservoir water resource of regulating and storing has remarkable economy, and its water supply cost generally is 1/5~1/10 of a face of land reservoir.Build regulate and store water resource in the basin of groundwater reservoir, development and use meaning for the inland river basin in arid zone water resource is very great, the inland river basin in arid zone water resource is not only very in short supply, and the spatial and temporal distributions inequality, in water resources development and utilization, the effect of the engineering of regulating and storing is very important, shortage is regulated and stored water resource that engineering causes, and invalid waste is very serious, water is by changing normal spring by the pouring in winter before the broadcasting of cotton, for obtaining same irrigation effect, it is clean irritate quota must be by 70m 3/ mu is increased to 110m 3/ mu, invalid and water resources quantity poor efficiency reaches 57%, medium and small basin, the landlocked river of arid biogeographic zone adopts the mountain reservoir water resource of regulating and storing to need certain one-tenth storehouse condition, for some landform or the comparatively abominable river of geological conditions, building face of land reservoir is often invested very huge, make the construction of engineering lose economy, simultaneously, the amount evaporation loss of the face of land, mountain area reservoir is generally 10~20% of reservoir capacity, Wall in Plain Reservoir is then more up to 25~40%, therefore, adopting the mode of groundwater reservoir that water resource is carried out regulating and storing on the space-time, is one of efficient means of utilizing of inland river basin in arid zone water resource.Little through flowing, drop is big, silt particle is many, flow process is short, no terminal lake is medium and small basin, the landlocked river of an arid biogeographic zone common characteristic, medium and small basin, the landlocked river of arid biogeographic zone, along the river flow by landform unit and vertically to be divided into the mountain area, alluvial-proluvial fan in front of the mountains, alluvial-proluvial plain, oasis and desert intermediate zone and desert, surface flow results from the mountain area, therefore, the mountain area is called the runoff yield district again, each landform unit in front of the mountains below the alluvial-proluvial fan is owing to infiltrate, evaporation is strong, runoff reduces gradually, so be referred to as surface flow dissipation district again, in surface flow dissipation district, since surface water go into to blend in front of the mountains the phreatic acting in conjunction of side direction, just formed a natural lower storage reservoir hugely at underground, this groundwater reservoir in the groundwater table of the lower edge of alluvial-proluvial fan in front of the mountains generally apart from ground 0~10m, the groundwater flow condition is good, transmission coefficient is generally at 20~100m/d, the underground water update cycle is short, therefore, here just become the desirable place that people large-scale develop and utilize groundwater resources, all the year round, utilize groundwater resources in order to exploit, people carried out unremitting effort, the history of underground water intaking gallery is remote more than Electrical Well, the kanat in Xinjiang is typical representative, be suitable for the radiation vertical shaft type collecting well (being commonly called as large open well) in the sand and gravel stratum, still by people's widespread.At present, medium and small basin, the landlocked river of arid biogeographic zone is in order to solve regulating and storing and shortage problem of water resource, adopt built face of land reservoir more, the technical scheme of dynamo-electric gang of wells and water intaking gallery are only as the ancillary method as the water resource of regulating and storing, though it is little that its main cause is that the technical method of dynamo-electric gang of wells has an one-time investment, control advantage easily, yet, it need adopt power-lift to ground the water yield in the well casing, operating cost is high, water yield of well is little, simultaneously, build and disperse, be unfavorable for concentrating of the water yield, be difficult to that the water yield is imported the trunk canal and be used to the water resource of regulating and storing, by the existing collection gallery groundwater reservoir technical method that the alluvial-proluvial fan place constitutes in front of the mountains, flow and the water intaking scope of catchmenting is very limited again, the small scale of the groundwater reservoir that forms can not effectively substitute the function of face of land reservoir, as: the scale of the kanat maximum in Xinjiang is 2m 3/ s, collection gallery is long, and uncontrollable flow is difficult to implement below sand ovum gravel aquifer, and existing radiation vertical shaft type collecting well is fought separately again, and the individual well scale is generally at 0.5m 3Below/the s, and needing the power water lift, therefore, although very outstanding, the disposable input of face of land reservoir caused " dam and environment " problem is huge, less economical, but still is the engineering mode of regulating and storing that generally adopt in medium and small basin, the landlocked river of arid biogeographic zone.

Fig. 3 is the structural representation of motor-pumped well formula water intake well 6, it and motor-pumped well are quite similar, it is that well casing 12 is provided with delivery port 13 that institute does not exist together, make the current gravity flow enter tunnel, delivery port 13 can directly enter charge for remittance tunnel 3, also can be by entering charge for remittance tunnel 3 after the general valve control, convenient in order to control, it is a kind of cheap that the present invention also provides, the weight piston type adjusting control valve of superior performance, it is to be provided with cavity Weight type piston 14 in motor-pumped well pipe 12, cavity Weight type piston 14 is and motor-pumped well pipe 12 piston movingly that it axially is being provided with the water flowing chamber of up/down perforation.Its cavity effect is the water yield that connects in the pipe up and down on the one hand, make launching stress unanimity on the cavity Weight type piston 14 on the other hand, it is up and down to be convenient to it, move up and down by control cavity Weight type piston 14, can control effective water-outlet area of delivery port 13, thereby reach the purpose of control and regulation water yield, because control is very convenient, therefore, adopt this control method highly beneficial to the realization automation control scheduling and the operation maintenance of this water intaking gallery.Fig. 4 is the structural representation of hybrid water intake well 7, it is mixed by motor-pumped well formula water intake well 6 and existing vertical shaft type water intake well and forms, it is provided with vertical shaft 15 on the top of motor-pumped well pipe 12, in vertical shaft 15, be provided with radiant type intake pipe 16, radiant type intake pipe 16 is an end opening, the pipeline of other end sealing, its openend is communicated with motor-pumped well pipe 12 or vertical shaft 15, and it is positioned at uniform inlet opening on the tube wall in aquifer 10.Radiant type intake pipe 16 directly can be fed in the motor-pumped well pipe 12 in order to control the water yield, on motor-pumped well pipe 12, be provided with delivery port 13, cavity Weight type piston 14 is installed in motor-pumped well pipe 12.The cost of hybrid water intake well 7 is higher, and main effect is to be convenient to that tunnel construction is slagged tap and operational management.Fig. 5 is the structural representation of radiation vertical shaft type water intake well 8, the steel pipe 12 that has water inlet is being set in vertical shaft 15, be distributed on the radiant type intake pipe 16 in aquifer 10, its openend and vertical shaft 15 connect, and by manifold trunk device 17 uniform radiant type intake pipe 16 openends are communicated with the water inlet of steel pipe 12, radiant type intake pipe 16 directly is communicated with steel pipe 12.
When stratum when being aquifer 10 with relative impervious layer 9 interlaced structures, the suitable preferred motor-pumped well formula water intake well 6 that adopts of the concrete pattern of water intake well, can expose relative impervious layer 9 like this, increase the leak factor of vertical shaft, thereby increase water withdrawal and widen the water intaking scope, the water withdrawal of water intaking gallery is improved.When the stratum structure was comparatively single, the concrete pattern of water intake well also can be chosen as radiation vertical shaft type water intake well 8.Slag tap conveniently and the operation maintenance facility for tunnel construction, in the layout of water intaking gallery, should establish a hybrid water intake well 7 every several vertical shafts, hybrid water intake well 7 can also be as middle collection station or the starting point in the jacking construction.
One of necessary condition of sand ovum gravel bed cavitation is that the groundwater table at tunnel place should be not too high, yet, it is again that this water intaking gallery is necessary below 11 that charge for remittance tunnel 3 is built in phreatic line, one of important part of the present invention, be to reduce the groundwater table at tunnel place by the formed funnel of the water intaking of vertical shaft, for the construction of tunnel creates favorable conditions, thus the present invention construction drainage and permanent water intaking, temporary works and permanent works are integrated, thereby engineering construction cost is greatly reduced.
In order to reduce the construction drainage expense, should adopt the gravity flow draining as far as possible, therefore, the construction that should make progress from the downstream of water intaking gallery, elder generation's construction diversion tunnel 4, back construction charge for remittance tunnel 3, first vertical shaft, back tunnel, camp step by step, thereby reach the purpose that reduces construction costs, meanwhile, because this water intaking gallery has adopted the mode based on vertical shaft, the water yield in the vertical shaft can be controlled again, so not only operation maintenance is convenient for the water intaking gallery, but and the limit construction, performance benefit in limit very is suitable for by stages, builds step by step.
This water intaking gallery also can directly be fetched water in the dark riverbed that covers, and suitable to the intermountain water intake system of lower storage reservoir and other pattern groundwater reservoir hollowly.
Now further brief concise description basic principle of the present invention: by the hydraulics theory as can be known the regime flow of a common complete well be:
Q = k H 2 + h 0 2 0.731 og R r 0
In the formula symbol see shown in Figure 6, the flow Q of motor-pumped well falls dark S with saturating coefficient k and design and is closely related, existing Electrical Well generally is arranged near the place, farmland, pumping equipment is among the well casing, general design is fallen dark many in 10m, be subjected to the influence of osmotic coefficient k, and consider operating line loss and power consumption, the individual well flow is many at 0.1m 3In/the S, and the delivery port of motor-pumped well of the present invention can be identical with the diameter of motor-pumped well, line loss is little, design is fallen deeply also can be in conjunction with the terrain slope design more than 10m, meanwhile, this water intaking gallery can be arranged in alluvial-proluvial fan lower edge top, and osmotic coefficient k herein is bigger, so can be with its individual well flow design bigger than existing Electrical Well.If this vertical water intake well by Fig. 1 be " one ' font is arranged; and establish impervious layer and be positioned at the gallery bottom; when the vertical shaft spacing is closeer; its computation model can be reduced to water intaking gallery as shown in Figure 8; the depth of water of gallery promptly is effective water intaking degree of depth of motor-pumped well; for the performance of this water intaking gallery that explains the main points briefly, now descending impervious layer hypothetically is flat slope, by the hydraulics theory as can be known its one-sided discharge per unit width be:
q = k ( H 2 - h 0 2 ) 2 L
This shows, fall in identical design under the situation of dark S that it is than big many of the water draw rate of common water intaking gallery, example, when dark S=20m falls in design, a h 0The common water intaking gallery of=3m is compared with this water intaking of motor-pumped well formula gallery that the degree of depth of effectively fetching water is 50m, its water draw rate is 6.1 times of common water intaking gallery, therefore, the scale of the groundwater reservoir that is formed by the present invention generally also can satisfy the regulate and store task of basin to water resource.
The landlocked river of arid biogeographic zone since surface water go into to blend side direction supply in front of the mountains, the interflow subsurface drainage amount of the lower edge of alluvial-proluvial fan generally accounts for 8~15% of discharge of river amount in front of the mountains, phreatic flow direction is general consistent with the earth grade direction, arrange this underground water intaking gallery along the underground contour of water table, can be by regulate and store water resource in the basin of aquifer, natural groundwater storehouse, the upstream water yield, if year water withdrawal of water intaking gallery is less than descending run-off natively, can be restored in formed exploitation funnel year, then can form a complete groundwater reservoir by this water intaking gallery.If year water withdrawal of water intaking gallery then needs to cover measure accordingly, thereby forms a complete groundwater reservoir greater than descending run-off naturally.Because, middle small watershed in front of the mountains as the natural groundwater storehouse before the alluvial-proluvial fan storage capacity very big, therefore, generally all have regulating power for many years by the formed groundwater reservoir of this water intaking gallery.
The interflow subsurface drainage water yield in the landlocked river of arid biogeographic zone, in entering the process of alluvial-proluvial plain, a part returns the face of land uniformly with the form of spring, another part dissipates with the form of evaporation from phreatic water and crop transpiration, when underground runoff water amount is big, the groundwater table at alluvial-proluvial plain place is too high with causing, make progressively salination of soil, the utilization rate of this part interflow subsurface drainage water yield is very low, utilize this water intaking gallery exploiting groundwater, not only uniform spring can be become the water resource that can regulate and store, and can effectively reduce the groundwater table at alluvial-proluvial plain place, therefore, the formed groundwater reservoir of water intaking gallery involved in the present invention has the dual performance of regulating and storing and efficiently utilizing water resource.
