The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
As shown in Figure 1 and Figure 2, irrigation and drainage pipes of the present invention comprises outer tube 1, the inner-walls of duct of outer tube 1 longitudinally is intervally distributed with the less water pipe of caliber 3,3 three one group, water pipe is arranged in a crossed manner and vertical with inner-walls of duct, article three, the central point that intersects of water pipe 3 is the axle center of outer tube 1, and the angle between two adjacent water pipes 3 is 60 degree.The top of water pipe 3 is fixed on inner-walls of duct, tube wall and its opening that the drain hole 2 of water pipe 3 bottoms runs through outer tube 1 are located on the outer wall of outer tube 1 bottom, also be provided with irrigation and drainage hole 4 on water pipe 3 tops, this irrigation and drainage hole 4 is located at higher than the position more than water pipe 3 body mid-heights, namely higher than the position of bottom more than 1/2.Irrigation and drainage hole 4 is circular, and according to the size of outer tube 1, irrigation and drainage hole 4 is provided with more than two or two, for example 2 to 10.
the present invention is when draining is used, due to irrigation and drainage pipes (outer tube) is embedded in soil, moisture content in silt particle around outer tube is after the high low head effect by hydraulic pressure, moisture content is just by the outer high-level position of pipeline, via the drain hole that is positioned at the outer tube bottom, infiltrate through in three little water pipes, tiny water irrigation and drainage hole through being arranged in three water pipe tops causes the outer tube supervisor again, in the process of this infiltration, moisture content is through being enclosed in pipeline outer soil and silt particle, can infiltrate through in drain hole, situation is just as the self-filtration through silt particle, can be with than larger volume or granular soil silt particle, the oneself is every filtering outside the drain hole of outer tube bottom.And above process of osmosis also makes to be enclosed in the outer soil silt particle of pipeline, can directly by moisture content, not driven, and rushes in drain hole, causes line clogging.and find in experiment, when moisture content infiltrates through the duct of drain hole, can find that moisture content has more obviously separating of two-part, namely that moisture content is as being mingled with the more part of soil composition, can rest on the downstream part in the drain hole duct, and be mingled with the comparatively a small amount of moisture content of soil composition, be positioned at upstream because be subject to the impact of volume and quality, just can be at first in the irrigation and drainage hole enters outer tube master derivation conduit, that is all are through drain hole, flow into again the moisture content in the tiny irrigation and drainage hole introducing outer tube main water pipeline in three little water pipes, only can be mingled with superfine little soil molecule, can not be accompanied with bulky grain soil or silt blocking pipeline, thereby make draining smooth and easy., when the soil outside pipeline and sandstone, after the self-filtration of silt particle, just only have imperceptible soil composition just can be mingled in moisture content, and be with and enter in the outer tube main water pipeline together thereupon.Enter the powerful current that driven in outer tube and trickle soil erosion can be gone out outside pipeline, so the irrigation and drainage pipeline also has the self-cleaning function.
the present invention is when irrigating use, when irrigation moisture content is introduced in outer tube, the horizontal level of irrigating moisture content also can be increased in pipeline near three irrigation and drainage holes that water pipe top is tiny, when the horizontal level of moisture content in outer pipeline higher than the irrigation and drainage hole of three water pipes the time, just produce the head pressure that is caused by two uneven positions of difference, and this head pressure, just can be with the irrigation moisture content in pipeline, be advanced in the irrigation and drainage hole on three water pipe tops in pipeline, irrigate moisture content recycling osmotic pressure, by the outer tube main channel, irrigation and drainage hole through inner three water pipes, be drained near the earth in three water pipe bottom discharge holes, directly allow earth absorb needed moisture content and nutrient, and can not irrigated moisture content by solar evaporation and weathering, reach water saving and regularly with quantitative environmental protection, irrigate purpose.And be placed in irrigation pipe in farmland, and also have another kind of purposes, be when heavy rainfall is arranged, will make farmland do not had by water logging, at this time just irrigation pipe change can be drainage system, the flow direction of water is just opposite when irrigating, thereby helps to discharge a large amount of ponding in farmland.Like this, the present invention namely has the automatic bidirectional translation function of irrigation and draining.
In addition, the present invention can regularly do the maintenance cleaning with special water under high pressure burnisher, strengthens task performance and the continuity working life of pipeline.
