preparation example Construction

[0052] The present invention also provides a preparation method of the above-mentioned water-saving composite infiltration irrigation pipe, comprising the following steps:

[0053] S1, prepare the permeation film layer.

[0054] S2, prepare the base layer of infiltration irrigation.

[0055] S3. In order to prevent the infiltration irrigation substrate layer from causing damage to the infiltration irrigation film layer, a protective inner layer is provided on the outside of the infiltration irrigation substrate layer prepared in step S2, and then the infiltration irrigation film layer prepared in step S1 is wrapped in the protection. outside of the layer.

[0056] Preferably, in order to prevent clogging inside the percolation base layer, a protective layer such as a sponge may also be provided inside the percolation base layer.

[0057] The above step S1 includes:

[0058] S11. Fiber pretreatment: In order to remove the oil on the surface of the fiber and improve its hydro...

Embodiment 1

[0075] This embodiment provides a water-saving composite infiltration irrigation pipe, which includes an infiltration irrigation substrate layer and an infiltration irrigation film layer disposed outside the infiltration irrigation substrate layer.

[0076] A plurality of interconnected capillary pores are distributed in the substratum of infiltration irrigation, and the plurality of capillary pores extend from the inside of the substratum of submersion to the inner surface and the outer surface of the substratum, and communicate with the outside world. The infiltration membrane layer is formed by compounding the water-conducting fiber and the membrane layer matrix. Both ends of the water-conducting fibers are exposed on the two sides of the film substrate. The water-conducting fibers include filaments and polyacrylamide-montmorillonite composite water-conducting materials coated on the surfaces of the filaments.

[0077] Wherein, the preparation method of the permeation film...

Embodiment 2

[0089] This embodiment provides a water-saving composite infiltration irrigation pipe. The difference from Embodiment 1 is that in the process of preparing the polyacrylamide-montmorillonite composite water-conducting material, the mass ratio of polyacrylamide and montmorillonite is 0.1.

Abstract

The invention relates to a water-saving type composite infiltrating irrigation pipe and a preparation method thereof. The water-saving type composite infiltrating irrigation pipe comprises an infiltrating irrigation base body layer and an infiltrating irrigation film layer on the outer side of the infiltrating irrigation base body layer. A plurality of mutually communicated capillary holes are distributed in the infiltrating irrigation base body layer, extend to the surface of the infiltrating irrigation base body layer from the interior of the infiltrating irrigation base body layer and are communicated with the outside. The infiltrating irrigation film layer is formed by compounding water guiding fibers and a film layer base body, and the two ends of the water guiding fibers are exposed on the two faces of the film layer base body respectively. The water guide fiber comprises cellosilk and a polyacrylamide-montmorillonite composite water guide material coated on the surface of the cellosilk. A plurality of mutually communicated capillary holes are formed in the infiltrating irrigation base body layer, and when the infiltrating irrigation base body layer serves as a pipeline inner layer to be filled with water, the water seeps to the outer side of the infiltrating irrigation base body layer from the inner side of the infiltrating irrigation base body layer along the capillary holes under the capillary action and reaches the infiltrating irrigation film layer. The infiltrating irrigation film layer can automatically adjust the water outlet rate according to the soil humidity, an active adjusting mode is adopted, water sources can be saved, and waste is avoided.

Description

technical field [0001] The invention belongs to the technical field of agriculture and forestry irrigation, and particularly relates to a water-saving composite infiltration irrigation pipe and a preparation method thereof. Background technique [0002] At present, the irrigation methods of farmland are mainly sprinkling irrigation and flood irrigation. However, the irrigation methods of sprinkler and flood irrigation limit the infiltration of water resources to the roots of plants through soil infiltration and other effects, and a large part of water resources directly evaporate on the surface and cannot flow effectively. To the root of the plant, the utilization rate is very low, and the waste is serious. [0003] In order to solve the problems of low utilization rate and serious waste of water resources caused by sprinkler irrigation and flood irrigation, in recent years, many scholars in my country have carried out research on underground infiltration irrigation. Infilt...
