A cracked seepage irrigation pipe and its processing method

Abstract

The invention relates to a cracked seepage irrigation pipe and a processing method thereof. The cracked seepage irrigation pipe is a tubular structure, including a pipe body, and a number of uniformly distributed cracks with the same direction are formed on the pipe body according to the fiber lines. The core layer of the tube body forms a hollow lumen, and the inner and outer surfaces of the core layer are both smooth surfaces. When water flows into the hollow lumen, under the action of water pressure, the water pressure makes cracks form gaps, and the hollow lumen The internal water flows out through the gaps formed by the cracks along the radial direction of the pipe body to realize water seepage irrigation. The cracked seepage irrigation pipe is not only high-quality, environment-friendly and pollution-free, but also can extend the distance of water delivery and irrigation, so that water seeps out from the cracks of the pipe, can increase production and income by more than 20%, and has remarkable economic benefits. Using the product of the invention can save water by more than 40% compared with spray irrigation, has high irrigation uniformity and high irrigation efficiency, and can promote the growth of crops.

Description

technical field [0001] The invention relates to the technical field of agricultural irrigation, in particular to a cracked seepage irrigation pipe and a processing method. Background technique [0002] With a steadily growing population, water is becoming more and more important, scarcer and more expensive. [0003] In the prior art, agricultural irrigation mostly adopts flood irrigation or sprinkler irrigation, and plants cannot fully absorb water, and most of the water is lost to the air due to evaporation or penetrates into the deep soil layer, resulting in a large amount of waste; and flood irrigation It can also have adverse effects on the soil, leading to soil erosion and the accumulation of salinity. [0004] Infiltration irrigation can solve the problems of waste of water resources and soil erosion, but the cracked infiltration irrigation pipes in the prior art have point-shaped water outlets, which are easily affected by water quality, especially impurities in the ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, agricultural irrigation mostly adopts flood irrigation or sprinkler irrigation, and plants cannot fully absorb water, and most of the water is lost to the air due to evaporation or penetrates into the deep soil layer, resulting in a large amount of waste; and flood irrigation It can also have an adverse effect on the soil, causing soil erosion and the accumulation of salinity

[0004] Seepage irrigation can solve the problems of water resource waste and soil erosion, but the cracked seepage irrigation pipes in the prior art are point-shaped water outlets, which are easily affected by water quality, especially impurities in the water are easy to block the water outlet holes, and it is difficult to clean

[0005] In addition, the cracked seepage irrigation pipe in the prior art is not uniform in water flow along the direction of water flow, the greater the resistance to the downstream water flow, the greater the pressure drop of the water flow, resulting in less downstream water flow than upstream water flow , which in turn leads to insufficient irrigation water for plants located downstream, affecting the balanced growth of plants

[0006] In addition, after the cracked seepage irrigation pipe is buried in the ground, due to the instinct of absorbing water, the roots of the plants will gradually grow towards the direction of the cracked seepage irrigation pipe. Pack tightly, causing pipe blockage
