SU1440361A1 - Method of controlling erosion of soil on slopes - Google Patents

Abstract

The invention relates to agricultural households and can be used during agroforestry measures on slopes, including gardens. The method is most suitable for areas with the predominant manifestation of erosion processes during the period of spring snow. The purpose of the invention is to increase the effectiveness of combating soil erosion on slopes by regulating runoff and increasing the volume of water absorption. For this purpose, a water control is created in the forest strip, which along the lower edge is aligned with a discontinuous trench cut along the water-v, diverting shaft. For better water absorption in the walls and bottom of the trench, we drill holes to a depth that exceeds the depth of soil freezing, and drain pipes from materials with high thermal conductivity are inserted into them. The tops of the tubes protrude above the ground surface to a height exceeding the mean multiyear height of the snow cover and are black for a quick spring dimension under the action of the sun's rays. 3 il. about

The invention relates to agriculture, in particular, to the protection of soil from erosion, and can be used when carrying out agricultural and land reclamation activities on C1slon, including in gardens. The method is most appropriate for areas with a predominant manifestation of erosion processes during the period of spring snow.

The purpose of the invention is to increase the effectiveness of combating soil erosion on slopes by regulating runoff and increasing the volume of water absorption.

FIG. 1 shows a forest belt, a general view of FIG. 2 shows section A-A in FIG. one; in fig. 3 - a section of a trench with placement of drill holes in the bottom and walls of the trench.

The method is compacted in the following way.

The planting of woody plants, the pattern of a water-regulating forest belt 1, is carried out along the slope and parallel to the pre-cut trench 3, combined with the drainage shaft 2, located iodine angle to the horizontal horizons of the terrain, providing non-splitting water outflow rates along shaft. In the bottom 4 and cfeHKax 5 of the trench 3 there are holes 6, into which drainage pipes 7 are inserted, the upper parts of which extend above the bottom surface to a height exceeding the mean-year high snow cover and have a black color. Pipes 7 are made of materials with high thermal conductivity.

A formation on the slope of a runoff, a passage through a clogging forest belt with one or two marginal rows of shrubs, is cleared of small earth and enters an intermittent water-absorbing trench, reinforced by drainage

pipes. Due to the black color of the parts of the drainage pipes that emerge over the day surface, they quickly heat up under the action of the sun's rays, thaw and begin to absorb water. The lower parts of the pipes, which are buried in the drilled holes, are below the layer of soil, which ensures that the absorbed pipe — i many water is absorbed. In addition, it passes through rubbing. The bam tala water warms the frozen soil layer adjacent to it, which also begins to draw in water.

If the flow from the catchment comes unevenly, with an intensity that exceeds the water absorption capacity of a particular section of the trench, then its excess flow down along the shaft, filling subsequent sections of the trench. This ensures a uniform redistribution of the flow along the entire length of the trench.

When all sections of the trench are absorbed with water, the water is transported along the shaft, ending up with a spillway or a spray spray.
