Abstract
The present invention provides a method for making membrane dam reservoir (pool). The membrane 2 clings to the dam 6, so the dam and the reservoir bottom become a water-tight integration. The siphon 4 having the shower nozzle 3 spans on the dam 6, the shower nozzle 3 extends into the inmost depth of the reservoir, another end outlet 9 extends into the lower part of the dam, the reservoir water flows into irrigation system via the outlet 9 of the siphon 4. Said membrane and siphon can be volume produced in factory.
Description
The invention provides the preparation method of a kind of film dam reservoir (pond).
Traditional reservoir engineering is that a designing requirement is tight, and the construction requirement strictness involves great expense and has the to a certain degree construction work of hidden danger.Though the making in pond need not tight design and strict construction sequence, needs fragment of brick and cement, with regard to the unit water retention capacity, cost is also higher than reservoir.The object of the present invention is to provide a kind of cheaply, the method in reservoir (pond) is built in easy construction and can be fast on the hillside on the foot of the hill and the mild ground.The present invention is specially adapted to a flood takes place once raining, the loess plateau building reservoir (pond) of one day fine drought that just makes a noise, keeping water and soil there, and reach that to save rainwater (comprising silt) on the spot on rainy day not a flood takes place, water vegetation and crop with the water of saving at fine day.Fundamentally administer the soil erosion in loess plateau, make whole loess plateau become mountain green grass or young crops, light green.
The preparation method of film dam reservoir is: address (the estimation collective area of selecting to build reservoir earlier, look for a corresponding comparatively smooth plot), determine to build the position of dykes and dams again, (for safety, the dykes and dams height is controlled at below 3 meters), on the dykes and dams position, built dykes and dams with the sandy soil in the location, storehouse then, selected suitable place system one groove simultaneously on the dykes and dams both sides, and leveling has been struck in fact in the dykes and dams surface as flood spillway by planning heap.At the bottom of the internal side of dyke or dam dam of newly building, dig Yi Tiaogou then; lay nylon membrane (two nylon membrane junction overlaid 10-15cm from bottom of trench to dykes and dams; overlapping ankyloses with glue; in order to avoid leak); treat that nylon membrane arrives bank; just ditch is filled and led up; one end of nylon membrane is embedded in the ditch; lay to dam crest at the bottom of being embedded in nylon membrane in the ditch by the dam; and climb over that dam crest is paved with whole dykes and dams surface downwards and surpass the dykes and dams soil moved in to improve the original, the following hillside of soil moved in to improve the original is covered 1-5 rice (purpose is that the protection dam foundation is not washed away by water).For preventing that strong wind from blowing afloat film and sunlight is aging to the catalysis of film, at the sandy soil that cover on the dykes and dams film more than the thick 1cm, the edge part to film thickeies compacting especially, or the limit ditching potting of film.Because dykes and dams have the gradient, film is very smooth again, is difficult to adhere to sandy soil.Therefore on the film on the dykes and dams, cover earlier one deck washable non-woven fabric, again at the sandy soil that cover on the nonwoven about 0.5cm, on sandy soil, cover one deck washable non-woven fabric again, at the sandy soil that cover again on the nonwoven about 0.5cm, but like this more than the triplicate, till guaranteeing that film on the dykes and dams is not subjected to the influence of strong wind and sunlight.Make dykes and dams and bottom of the reservior become a watertight integral body.
Next be the irrigation and drainage of storehouse water.Siphon principle is used in the derivation of storehouse water, settles a syphon to push up to dykes and dams from the bosom, bottom of the reservior, climbs over the dykes and dams top again and extends to feed ditch or the pipeline that waters.Big syphon side one outside the dykes and dams top has the water irrigating hole of seal cover, and syphon extends downward certain position in the dykes and dams outside, puts a draining valve.Close draining valve, open the seal cover of water irrigating hole, pour water in syphon, water is just in the siphon of storage on draining valve, when spill-over during to water irrigating hole, just close the seal cover of water irrigating hole, open draining valve then, because the atmospheric pressure effect, the air when current are discharged in the syphon is taken out of, siphonage forms, and reservoir water just flows into irrigation system by syphon.As stopping irrigation and drainage, as long as open the port lid of pouring water, air enters syphon, and siphonage is ended.
On the loess plateau, make film dam reservoir, can answer ground suiting measures to different conditions in corrie, from top to bottom in layer to build with reference to the mode of construction of terraced fields, (it is also more convenient than building terraced fields to build terrace-type film dam reservoir), can hold rainwater and silt in the film dam reservoir of staying on the spot in the rainy day like this, when silt piles with film dam reservoir, just can easily build a new film dam reservoir again as long as in dykes and dams, build new film dykes and dams again.For stoping ovum under storehouse water evaporation and the summer mosquito, can on the water surface, drip the very little oil product of surface tension, make the water surface float the extremely thin oil film of one deck, oil product must be a modified vegetable oil, enters energy natural decomposition behind the soil.
The present invention is further elaborated with diagrammatic sketch below, and in the diagrammatic sketch 1, film 2 is close on the dykes and dams 6 behind the seamless.In the diagrammatic sketch 2, the syphon 4 that is shaped on shower nozzle 3 collapses on dykes and dams 6, the shower nozzle 3 of syphon 4 one ends stretches into the reservoir bosom, other end outlet 9 extends the dykes and dams below, syphon 4 pushes up 7 outsides at dykes and dams and is equipped with the water irrigating hole 5 that can open and close seal cover, the top of outlet 9 is equipped with draining valve 8, close draining valve 8, open the seal cover on the water irrigating hole 5, from water irrigating hole 5, in syphon, pour water,, just close seal cover when water level rises to water irrigating hole 5, open draining valve 8 again, water in the pipe is just discharged from exporting 9 by draining valve 8, and under the atmospheric pressure effect, originally the air in syphon is discharged from exporting 9 with current, siphonage forms, and storehouse water just discharges by syphon 4.When need stopped to discharge, as long as open seal cover on the water irrigating hole 5, air entered syphon 4, and siphonage is ended, and draining stops.
Film 2 of the present invention and syphon 4 can be produced in enormous quantities in factory.
Claims (2)
1, the preparation method of a kind of film dam reservoir (pond) is characterized in that: film 2 is close on the dykes and dams 6, and syphon, climbs over the dykes and dams top again and extends feed ditch to dam crest from the bosom, bottom of the reservior.
