Able to resisting flood and drought.
Background technique
Karst depression refers to the bottom flat formed by karstification, and area is larger, conducive to the closing negative land form of cultivation.?
The subterranean stream in karst depression area, it is multiple to give birth to the spilling water skylight and sinkhole communicated with earth's surface, and these spilling water skylights and overboard
Hole is nearly all located at the bottom of karst depression.Rainy season underground stream stage, which goes up, to be overflowed by spilling water skylight and sinkhole, usually
Farmland is flooded, large area, long-time flood are caused；Dry season majority surface layer karst source is dry, and rare precipitation is also usually by spilling water
Skylight and sinkhole leakage, lead to drought and water shortage, crop production reduction, while also influencing periphery human livestock drinking water safety.This is asked
It inscribes more universal in Southwest China Karst Areas.
Normal practice is:
(1), gutter is built, rainy season flood is directly discharged into disappear water hole and the earth's surface river valley in subterranean stream downstream.This method
Existing main problem is: flood is directly discharged into downstream and disappears water hole and earth's surface river valley, does not on the one hand utilize the part resource rationally,
On the other hand downstream pool and earth's surface river valley load are increased, further causes flood.
(2), it in the spilling water skylight and sinkhole that karst depression bottom is blocked up, made ground is gone to river, avoids gushing on flood period underground water.
Main problem existing for this method is: due to the inhomogeneity of karst depression development, simply blocking up, fills out spilling water skylight and sinkhole
It cannot be effectively prevented on underground water and gush, also will cause the waste of front capital.
Both the above Normal practice or only solution flood or only solution arid, and there is some intrinsic lack
It falls into.It there is no the project slash that can be solved the above problems simultaneously at this stage.

Hole surrounds, and the highest reserve-water-level of reservoir must not be lower than at the top of water outlet；
The water outlet is equipped with immersible pump, and immersible pump can be put into subterranean stream by water outlet and carry out water lift storage library；
The reservoir is connected to water factory by aqueduct, for the water of reservoir to be delivered to water factory's central water supply, the water
Library postlude has built flume, disappears water hole or power station for the water of reservoir to be drained into downstream, or is used for periphery field irrigation.
The pipeline blocks up body as a preferred embodiment of the above solution, reservoir is built using armored concrete, water outlet, aqueduct
Using steel construction, flume is built using brick mix structure.It conveniently builds, saving is built and installation cost, and ensures integral strength.
Further preferably, the reservoir bottom is provided with waterproof layer, carries out anti-drain process.
Further preferably, reservoir has been built on the way in the flume two sides, it is generally existing to solve Karst Mountain
Water shortage problem.
Further preferably, water level monitor is installed in the upstream face that pipeline blocks up body, to control underground stream stage in real time
The variation of water is put into the depth of subterranean stream according to situation of change balancing reservoir water level and immersible pump.
The utility model has the beneficial effects that
(1), reservoir and pumping equipment are built in the throat for intercepting subterranean stream, effectively alleviate karst depression because of rainy season
Flood problem caused by underground stream stage goes up；
(2), immersible pump water lift and reservoir filling efficiently solve karst depression area dry season problem of water consumption；
(3), aqueduct net laying is set and flume is built, and alleviates subterranean stream downstream human livestock drinking water and dry season field irrigation
Problem；
(4), diversion and power, the expensive problem of alleviation remote mountain areas power shortage, electricity consumption；
(5), it ensure that karst depression area farmland irrigation water, slow down the damage caused by waterlogging of depression bottom, be conducive to improve farming
Produce amount, improves local farmers income, and promotion is precisely shaken off poverty.
In conclusion the utility model is by " blocking up, proposing, storing, drawing " able to resisting flood and drought system in karst depression area arrangement, effectively
It solves the flood of karst depression area, while alleviating karst depression area drought and water shortage problem, and combine local agriculture, industry hair
Exhibition, improves groundwater resources utilization rate.
Detailed description of the invention
Fig. 1 is the simple diagram of the utility model.
Fig. 2 is the position signal of karst depression in the utility model, reservoir and subterranean stream.
Specific embodiment
By way of example and in conjunction with the accompanying drawings, the utility model is described in further detail:
As shown in Fig. 1-Fig. 2, subterranean stream 1 is located at the lower section of karst depression, the bottom of karst depression naturally occurred with
The spilling water skylight and sinkhole 5 that subterranean stream 1 communicates.Spilling water skylight and sinkhole 5 have several, but are nearly all located at karst depression
Bottom.
A kind of able to resisting flood and drought system for karst depression area, also referred to as " blocks up, stores, proposing, drawing " engineering, comprising:
" stifled ": testing in conjunction with survey for the purpose of locating hydrogeological resources, physical prospecting, and establishes model and try stifled test and find the water that disappears, spilling water
Subterranean stream has built pipeline in the throat of subterranean stream 1 and has blocked up body 2 for cutting lifting 1 water level of subterranean stream.Preferably, for reality
When control subterranean stream water level and flow variation, water level monitor 3 is installed in the upstream face that pipeline blocks up body 2, according to situation of change
4 water level of balancing reservoir and immersible pump 7 are put into the depth of subterranean stream.Pipeline blocks up body 2 and builds preferably with armored concrete.
" storage ": in karst depression area, bottom trimming has reservoir 4, and covers the spilling water skylight and sinkhole in karst depression area
5.Reservoir 4 is built in karst depression area bottom, just can covering spilling water skylight and sinkhole 5.First to spilling water skylight
And sinkhole 5 is modified, and the spilling water skylight that is each covered of face and sinkhole 5 build the water outlet 6 of chimney-like,
6 bottom of water outlet surrounds spilling water skylight and sinkhole 5, and the highest reserve-water-level of reservoir 4 must not be lower than at the top of water outlet 6, is prevented
