Retaining device for prevention and control of water soil erosion

Abstract

The invention discloses a retaining device for prevention and control of water soil erosion, and belongs to the field of soil and water conservation. The retaining device comprises a plurality of groups of side plates, cross plates and blocking meshes, the multiple groups of the side plates constitute a plurality of 'mouth' shapes, the multiple groups of cross plates are arranged between the side plates, and the cross plates are provided with through holes. According to the retaining device, soil is separated in to a plurality of small pieces through the side plates, the cross plates and the blocking meshes, water soil erosion is avoided through the cross plates and the blocking meshes, water is convenient to permeate through the through holes, the situation that the soil is taken away when water flows is avoided, erosion of the soil is reduced, moving of the transverse soil is reduced through the blocking meshes, meanwhile rooting of planted plants is convenient, growth of the plants is facilitated, the retaining device is convenient to replace and maintain, the using cost is reduced, using is convenient, meanwhile, plants with the drought enduring performance or developed roots can be planted in the filled soil according to the actual situation, water soil erosion is further assisted to be reduced, environment protection is improved, and using is convenient.

Description

technical field [0001] The invention relates to the field of water and soil management, in particular to a holding device for preventing and controlling water and soil loss. Background technique [0002] Soil erosion refers to the phenomenon that due to the influence of natural or human factors, rainwater cannot be absorbed on the spot, flows downhill, and scours the soil, resulting in the simultaneous loss of water and soil. The main reasons are the large slope of the ground, improper land use, destruction of ground vegetation, unreasonable farming techniques, loose soil, deforestation, overgrazing, etc. The harm of water and soil loss is mainly manifested in: the soil cultivation layer is eroded and destroyed, which makes the land fertility gradually exhausted; silting up rivers, channels and reservoirs, reducing the benefits of water conservancy projects, and even causing floods and droughts, seriously affecting industrial and agricultural production; Agricultural produc...

AI Technical Summary

Problems solved by technology

The harm of water and soil loss is mainly manifested in: the soil cultivation layer is eroded and destroyed, which makes the land fertility gradually exhausted; silting up rivers, channels and reservoirs, reducing the benefits of water conservancy projects, and even causing floods and droughts, seriously affecting industrial and agricultural production; Serious threats to mountain agricultural production and downstream river courses

[0003] The existing control of water and soil loss is getting more and more serious, and the corresponding treatment equipment is less, which cannot reduce water and soil loss well, and is likely to cause environmental damage
