Method for suppressing water and soil erosion of slope

Abstract

The invention discloses a method for suppressing water and soil erosion of a slope. The method includes the steps that (a) intercepting fence units are fixedly arranged on the slope, wherein each intercepting fence unit comprises two vertical bamboo piles, transverse strip-shaped connecting pieces are fixedly connected to the upper and lower parts of the two bamboo piles respectively, a bamboo netis fixedly connected in a space defined by the bamboo piles and the connecting pieces, tips are arranged at the lower ends of the bamboo piles, the tips of the two bamboo piles are vertically tampedinto the slope along the contour line of the slope, and then the intercepting fence units are fixed to the slope; (b) the space of the side, opposite to the intercepting fence units, of the slope is filled with macadam, wherein the macadam is formed by mixing macadam with the particle size of 1-5 mm with macadam with the particle size of 5-50 mm in the volume ratio of 1:(30-40). The method is economical and practical, provides convenience for construction and can effectively suppress soil and water erosion of the slope.

Description

technical field [0001] The invention relates to the technical field of water and soil conservation, in particular to a method for suppressing water and soil loss on slope land. Background technique [0002] Soil erosion refers to the use of land by human beings, especially the unreasonable development and management of water and soil resources, so that the soil cover is destroyed, and the bare soil is eroded by water, and the loss is greater than the amount of soil formed by the parent material layer. The loss is from topsoil loss, core soil loss to parent material loss, and eventually the rock is exposed. [0003] Land is a non-renewable resource, and there are many lands that are not conducive to development in my country. The fragile ecological environment and irrational use of human beings have caused many problems to the land. Issues such as land desertification, soil erosion, and changes in cultivated land have aroused widespread concern. [0004] my country is a mou...

Problems solved by technology

[0005] The current method of reducing soil erosion, such as the hedgerow method, is to select suitable grass and shrub plants according to the local geological conditions, and form a dense fence through the planting density between the plants to achieve the purpose of preventing soil erosion, but the implementation period of this method is long ,higher cost

There is also the method of using bamboo raft piles. By connecting multiple bamboo rafts together and knocking multiple bamboo rafts into the bottom of the slope to form a barrier, the purpose of preventing soil erosion is achieved. This method has a long construction period and the effect is not obvious. Therefore, , need a convenient, fast, practical, economical and effective method to suppress soil erosion in slope land
