The specific embodiment

The present invention is described in further detail hereinafter with reference to drawings and Examples.

Referring to Fig. 1 to Fig. 4, a kind of have prevent erosion and the plastic well of water supply function, comprise big funnel 1 and the little funnel 4 made with foamed plastics, outlet pipe 5, by the plastic flexible pipe 6 that plastic sheeting is made, plastic conduit 7 and polybag 8; Described big funnel 1 is provided with breach 2, and the rainwater in the plastic well surrounding soil can be flowed in the plastic well by described breach 2, on the described big funnel 1 overlap 3 is housed; Described little funnel 4 is bonded on the described big funnel 1, and described outlet pipe 5 passes described big funnel 1 and described little funnel 4, and described outlet pipe 5 is bonding with described big funnel 1 and described little funnel 4; Described plastic flexible pipe 6 is fixed on the described outlet pipe 5, described polybag 8 is tightened on the described overlap 3 that is fixed on described big funnel 1, described plastic conduit 7 is the L type, one end is installed on the described little funnel 4, the other end passes described polybag 8 and enters soil, can at described little funnel 4 different directions a plurality of described plastic conduits 7 be installed simultaneously, supply water to a plurality of directions simultaneously.

Referring to Fig. 5, dig a round pool on ground, plastic well is put into the hole, big funnel 1 is wanted 3-5 above ground level centimetre, prevents that the earth sandstone are entered in the well by big funnel 1 at ordinary times, and the breach 2 on the big funnel 1 need be lower than ground 2-3 centimetre, rainwater in the plastic well surrounding soil can be flowed in the well by breach 2, breach 2 on the big funnel 1 can be two or four, but can not be too many, otherwise can cause a large amount of earth sandstone to flow in the well.Breach 2 does not contact with soil, need open a tank in the place of alignment notch 2, allows plastic well water on every side be pooled in the tank like this, flows in the plastic wells by breach 2.

The diameter of polybag 8 is than the big 1.3-1.5 of diameter times of round pool, the degree of depth of plastic well is still like this, after like this can plastic well filling water, polybag 8 is unlikely to burst, need to be equipped with 2-3 kilogram earth in the polybag 8 simultaneously, play the effect of fixed plastics well like this, prevent that strong wind from blowing out round pool with plastic well.

Overlap 3 on the big funnel 1 is used for fixing polybag 8, and plastic well is stuck in the soil, prevents that plastic well from being blown away by wind.The degree of depth in hole should be 5 times of local amount of precipitation or darker, prevents to suddenly rain cats and dogs plastic well many as far as possible some rainwater of storage of can trying one's best.When the water of plastic well storage did not reach plastic flexible pipe 6, because the attraction of hydrone, the lower end of plastic flexible pipe 6 will be closed, and the water of well storage just can't be evaporated to air and cause loss like this.If rain, under the action of gravity of rainwater, plastic flexible pipe 6 can flow in the well by water by opening.The length of plastic flexible pipe 6 should be 4-5 times of outlet pipe 5 diameters, is convenient to plastic flexible pipe 6 and remains silent.

When arid does not have rainwater, the water of storing in the plastic well can form steam and condense into water droplet and attach in big funnel bottom, when the water that attaches when big funnel bottom is abundant, can flow downstream in the little funnel 4, flow into soil by the plastic conduit of installing on the little funnel 47.On the little funnel 4 many plastic conduits 7 can be installed, thereby supply water to a plurality of directions simultaneously, so just can supply water for growing plants around the plastic well.If cover the plastic foil of certain area again at this place, evaporation of water will reduce greatly, and the utilization rate of water can increase greatly.Need to prick several apertures with sewing-needle on the big funnel 1, prevent that air pressure is too high in the plastic well, bad big funnel 1 expands.

Plastic well mainly is used in the area that water and soil is easy to run off, comprise Loess Plateau and mountain area, the concrete size of plastic well can be by the concrete condition decision of each department, 0.07 hectare can be installed about 60 plastic wells, can there be general 1/10th soil to be capped, so just can prevent erosion, can storage of water provide moisture again for the surrounding plants growth.
