A Soil and Water Conservation Structure for Preventing Soil and Water Loss in Loess Area

Abstract

The invention discloses a water and soil conservation structure for preventing and controlling water and soil loss in loess areas, which comprises a protective net body used for water and soil conservation on slopes in loess areas, and the protective net body is composed of four sides and several connections between the four sides The four side lines are used to support and connect the surroundings composed of several connecting lines. This soil and water conservation structure for preventing and controlling soil erosion in the loess area can closely fit the slope of the loess area. Under the connection of several fixed-point adjustment devices, not only can the corresponding connecting lines closely fit on the slope of the loess area with "vertical and horizontal ravines", but also when the depression increases, it can be manually inspected regularly. Therefore, the areas and positions of several connecting lines corresponding to the depressions can be adjusted to realize effective local adjustment of the protective net body, further retain the loess in the depressions, and improve the soil and water conservation effect in the loess area.

Description

technical field [0001] The invention relates to the technical field of soil and water conservation structures, in particular to a soil and water conservation structure for preventing and controlling soil erosion in loess areas. Background technique [0002] Soil erosion is the damage or loss of soil and water resources and land productivity under the combined action of hydraulic, gravity, wind and other external forces and factors, including land surface erosion and water loss; [0003] At present, the existing high loess slopes are prone to loss of soil and water due to the scarcity of vegetation, heavy rains in summer, loose and easy soil, and thousands of ravines on the surface. . [0004] At the same time, the topography of the loess high slope is a relatively flat loess plateau, and then the slope surface is followed by a valley surface. However, the existing loess high slope formed by the vertical and horizontal slopes of the ravines is not only eroded by rainfall whe...

AI Technical Summary

Problems solved by technology

[0003] At present, the existing loess high slopes are sparsely covered with vegetation, heavy rains in summer, loose soil, easy to contain, thousands of ravines on the surface, and water and soil on the broken surface are easy to be lost;

[0004] At the same time, the topography of the loess high slope is a relatively flat loess plateau, followed by a slope and then a valley. At the same time, to a large extent, a large amount of rainwater flows in from the loess plateau at the top, and the rainwater inflow there is relatively concentrated, and at the same time the weight is heavy, and in the case of heavy rain, it is easy to cause the stones to roll down, and when the stones roll down When the soil is loosened, it will flow with the water flow, which will further lead to serious soil erosion in the loess area, causing the slope to form a "ravine vertical and horizontal" landform. Although the existing protection net is used to tighten the slope However, when the inner depression of the protective net increases, it will be difficult to adjust the position of the protective net in a large area, and at the same time affect the effect of water and soil conservation. Therefore, we propose a water and soil conservation structure for preventing and controlling soil erosion in loess areas
