Abstract

The utility model relates to a microscopic hole hose for irrigation of the cultivation of fields. The utility model is made of a plastic hose whose diameter is not greater than 8 mm. The hoses have inner and outer two layers. Through holes whose diameters are smaller than 0.15 mm are distributed on the walls of the two layers of hoses. Since the utility model adopts hose material, erection is not needed, the cultivation is not influenced, and laying, movement, and retraction are convenient. The material has low cost.

Description

Infiltrating irrigation micropore flexible pipe

A kind of cultivation of fields infiltrating irrigation micropore flexible pipe.

Since the human own cultivation of fields technology, irrigation is exactly an indispensable important ring in this technical regulation.

The main natural precipitation of accusing is irrigated in original land for growing field crops, and the land for growing field crops income does not ensure.

Along with the continuous development of human civilization, great variation also constantly takes place in the land for growing field crops irrigation technique.Now the land for growing field crops irrigate except that poverty or the abominable area of physical features still mainly by the natural precipitation, main flood irrigation, sprinkling irrigation and the drip irrigation technique of adopting irrigated in most of land for growing field crops.

Flood irrigation mainly adopts the method for repairing canal to carry out, and is the most traditional irrigation form; Sprinkling irrigation is undertaken by the pipe network with pressure.This form is advanced, compares with flood irrigation, can water-saving 50%; Drip irrigation also is to adopt the form of pipe network to carry out.Laying pipe network in big field, is splashed into the land for growing field crops with water along being distributed in tube wall hole on every side, and this method is than flood irrigation water-saving about 70%.

Though above method respectively possesses some good points, but still have the obstruction farming, can not make full use of water resource, engineering expends bigger shortcoming.

The purpose of this utility model be will be by the micropore flexible pipe design, start the land for growing field crops infiltration irrigation technology, it is low to reach engineering cost, does not hinder farming, compares with flood irrigation, 80% the purpose of can economizing on water.

The utility model is not more than 8 with diameter " plastic flexible pipe make, flexible pipe divides inside and outside two-layer, is distributed with the through hole of diameter less than 0.15mm on the wall of two-layer pipe.

The course of work of the present utility model is as follows: the irrigation pipe network of doing when use the utility model is in water filling during the stage, and the aperture of tube wall is too small, and water can not flow out from the hole.After the pipe network fills with water, with the increase of ductwork pressure, the water in the pipe network can slowly ooze out from the micropore of all tube walls simultaneously.Satisfy the requirement that the land for growing field crops is irrigated, reach the purpose of saving water resource.

Because the utility model adopts hose material, so need not set up, does not hinder farming, convenient auxilliary establishing moves and pack up, and Master Cost is low, and promotional value and application prospect are widely arranged.

Fig. 1 is the new structural representation of this practicality, also is that specification digest is with scheming.Fig. 2 is the duct ligation composition, and each numbering is respectively among the figure: 1 pipe, 2 micropores, 3 interior pipes.The micropore shape that on tube wall, is evenly distributed.

Now provide embodiment in conjunction with the accompanying drawings.

Managing 1 diameter is 4 °, and interior pipe 3 diameters also are 4 ";

Micro-pore diameter is 0.05mm;

Flexible pipe is manufactured with pvc material.

Claims

A kind of cultivation of fields infiltrating irrigation micropore flexible pipe is not more than 8 with diameter " plastic flexible pipe make, it is inside and outside two-layer to it is characterized in that flexible pipe divides, and is distributed with the through hole of diameter less than 0.15mm on the wall of two-layer pipe.
