Abstract
The present invention utilizes the technology of a plastic pipeline used for the infiltrating irrigation of a farm field. The present invention aims to make a plastic infiltrating irrigation pipeline by utilizing existing cheap materials which are easily obtained or waste plastic, utilizing existing semi-finished products, or utilizing existing equipment. The plastic infiltrating irrigation pipeline has the advantages of simple manufacture, low investment, water saving irrigation and drought resistance. The present invention has one method that an existing green hard plastic drainage pipe with a corrugated wall on the market is utilized, the diameter of the drainage pipe is 22mm, and the infiltrating irrigation pipeline is made by small holes which are arranged on the wall of the drainage pipe. The present invention has the other method that three different corrugated plastic tabs are made of waste hard plastic, and the three different corrugated plastic tabs are made into a triangular infiltrating irrigation pipeline. The infiltrating irrigation pipeline is embedded under the plough horizon, water is quantitatively supplied at definite times, the soil layer of the root system of crops can maintain wetness, water which is leaked underground is prevented, the ground surface which is hardened is prevented, and water which is evaporated on the ground is prevented.
Description
(1) technical field:
The present invention relates to a kind of agricultural water conservancy projects, relate in particular to a kind of plastic pipe for osmotic irrigation that is used for the farmland water-saving irrigation.
(2) background technology:
Farmland irrigation water is the most eager, and the water consumption and the waste water yield are all huge, and main because China farmland is based on flood irrigation.Flood irrigation is to underground leakage water and cause the face of land evaporation of hardening, and it is too big to waste the water yield.Because China water source is in short supply, the farmland drops in production over a large area because of arid so that have no harvest again, and the drought-hit area masses are difficult because of drought and water shortage livelihood dimension.At present the tentative various agricultural water-saving irrigation technology in various places as sprinkling irrigation, drip irrigation is all expensive because of material, investment is big, technical sophistication, the equipment easy-to-rust is easily aging, irrigation installation hinders farming operation etc. former thereby be difficult to promote on the ground.Some of Chu Xianing have water-saving result preferably with the technology and equipment that pipe for osmotic irrigation carries out infiltrating irrigation under the soil layer in recent years, but simultaneously some shortcomings are arranged again, and for example pipeline easily stops up, and difficulty is big when drift in the mediation pipe blow-through and dismounting; Underground piping can not bear excessive pressure, hinders mechanical cultivation on the ground.
The purpose of this invention is to provide a kind of be convenient to pipeline dismounting desilting and protection, can bear the farming operation mechanical pressure, the pipe for osmotic irrigation of not overslaugh farmland mechanical cultivation.
(3) summary of the invention:
This plastic pipe for osmotic irrigation is realized in the following manner:
Making three kinds of length with the elasticity duroplasts all is the long plastic sheet of 2000mm, and its title is respectively a bottom side sheet 1, and left side sheet 2 all has the corrugated groove 4 of broad ways on 3, three kinds of plastic sheets of right side sheet.Sheet wide 28mm in bottom side does not have the infiltration hole on it.The wide 28mm of left side sheet, sheet wide 32mm in right side has infiltration hole 5 on left side sheet and the right side sheet, and triplex row is lined up along the length direction of left side sheet and right side sheet in the infiltration hole, and the hole bit interleave is arranged.All there is knuckle limit 6 along its length the broadside both sides of three kinds of plastic sheets, and the dihedral angle of knuckle limit and lateral plate interarea is 60 °, knuckle hem width 8mm.The aqueduct 7 mutually nested in twos three kinds of plastic sheet knuckle limits, that just to constitute one section cross section be equilateral triangle.More than be the first kind of configuration and the nesting method of plastic pipe for osmotic irrigation.
It below is second kind of configuration and nesting method: bottom side sheet 8, left side sheet 9, all there is nested snap-fastener 11 at the broadside two ends of right side sheet 10, snap-fastener be make respectively at the broadside two ends of three kinds of plastic sheets along its length outer folding along 12 and invagination along 13, outer folding edge and invagination all are 120 ° along the dihedral angle with the lateral plate interarea, between outer folding edge and invagination edge is by catching groove, and there is snap-fastener plush copper 14 outer end on invagination edge.Utilize this snap-fastener can three kinds of plastic sheets are mutually nested in twos, constitute one section plastic pipe for osmotic irrigation 15 jointly.The length of pipeline can be used the bottom side sheet, the left side sheet, and the right side sheet is nested and extend in the irregular dislocation that prolongs seam crossing.
The good effect of this plastic pipe for osmotic irrigation is:
1. infiltrating irrigation under the soil layer, water saving, the saving of labor, soil does not harden, and pipeline is not tight to the pure and impure degree requirement of irrigation water, can use multiple water source.Plastic conduit is embedded in underground difficult aging, easily protection.
2. pipeline configuration has certain compressive resistance, with the pipeline drift angle upwards, downside wall under imbed in the soil layer, can reduce the perpendicular pressure of the tillage machinery that tube wall bears, thereby increase the compressive resistance of pipeline, do not hinder mechanical cultivation on the ground.
3. duct wall is divided into three, makes manufacturing, and storing and protection are quite easy, can be nested into pipeline easily when needing, and also can arbitrarily take apart to remove inner drift or change and repair.
(4) description of drawings:
Below in conjunction with accompanying drawing this plastic conduit is described further:
Fig. 1 is two kinds of configuration comparative illustration figure of this triangle pipe for osmotic irrigation.
Fig. 2 is that this pipeline configuration is simple with the structure and the sizing specification figure of the triangular-section pipe for osmotic irrigation of knuckle limit nesting method formation, and cost easy to manufacture is low.
Fig. 3 is structure and the sizing specification figure with the triangular-section pipe for osmotic irrigation of snap-fastener nesting method formation, and the pipeline comparatively robust of this configuration, configuration are complicated.
(5) embodiment:
When laying this pipeline, excavate groove in the fields, the width of groove so that tubing be advisable.The degree of depth of groove and the spacing of groove should be determined with reference to the situation of kind plant.Channel bottom requires straight.
Three kinds of plastic sheets are nested into the pipeline in equilateral triangle cross section, and the length of pipeline can be used bottom side sheet, left side sheet, and the right side sheet connects in the irregular dislocation of lengthening seam crossing and prolongs, and prolongs necessary position such as seam crossing and can prick solid with adhesive tape.Pipeline bottom side sheet is tiled in channel bottom, and the angle rib that left side sheet and right side sheet constitute is then vertically gone up and is placed.The soil backfill is gone in the groove, soil layer must be trampled tight around the pipeline again.Can and disperse mechanical pressure by the soil layer reinforcing pipes, and be beneficial to the soil layer infiltration.
If pipeline is stopped up by inner drift, as long as remove the pipeline surrounding soil, pipeline can be taken into three kinds of plastic sheets again apart, removes after the drift, and suit gets final product again again.
