specific Embodiment approach

[0052] Infiltration irrigation is an advanced water-saving irrigation technique in which irrigation water seeps through an infiltration irrigation pipe buried in the underground soil layer under a certain irrigation pressure, and moistens the soil by means of soil capillary action. At present, the application of infiltration irrigation technology is mostly extensive application of engineering. It is rare to establish mathematical models and calculation simulations based on the seepage capacity of infiltration irrigation pipes and the parameters of soil water conductivity, and finely optimize the design of parameters such as the depth of the buried pipe and the incoming flow head. This patent aims at the infiltration irrigation pipe buried in the slope, and invents the best buried depth of the infiltration irrigation pipe. The specific implementation is as follows:

Abstract

The invention relates to an infiltrating irrigation method and system suitable for an artificial revegetation slope. The infiltrating irrigation system comprises a high-level water storage tank (1), awater pumping device (3), water conveying pipes, infiltrating irrigation pipes (5) and the artificial revegetation slope; the high-level water storage tank (1) is arranged on the upper portion of theslope, the outlet end of the water pumping device (3) is connected with the high-level water storage tank (1) through a water source transmitting pipe, and the water conveying pipes and the infiltrating irrigation pipes (5) are buried in a soil layer of the artificial revegetation slope; the infiltrating irrigation system is buried in soil, so that irrigation water directly acts on roots of plants, and the problem of large water evaporation caused by surface irrigation is solved; because the infiltrating irrigation pipes are directly buried in the soil, it is unnecessary to additionally arrange hard pipes inside the soil to support the infiltrating irrigation pipes, the infiltrating efficiency is improved, and the cost is saved.

Description

Technical field [0001] The invention belongs to the field of irrigation, and specifically relates to an infiltration irrigation design method and system suitable for artificial revegetation slopes. Background technique [0002] Traditional irrigation methods are rough, and irrigation efficiency is low. Although sprinkler irrigation and drip irrigation technology have been applied maturely, this problem is often not solved very well for slope problems. On higher slopes, sprinkler irrigation water will flow quickly along the slope, causing the water to not penetrate into the soil. Drip irrigation can slowly infiltrate water into the soil, but it is still a surface irrigation method. For arid areas, the evaporation of soil surface water is large, and most of the irrigation water will still be evaporated. Infiltration irrigation is an advanced water-saving irrigation technique in which irrigation water seeps through an infiltration irrigation pipe buried in the underground soil laye...
