Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of water and soil conservation, specifically relates to a retaining device for water and soil conservation. BACKGROUND

[0002] Water and soil conservation refers to the prevention and control measures taken against water and soil loss caused by natural factors and human activities. Due to severe vegetation damage caused by water and soil loss, the soil is fixed by blocking to improve the current situation of water and soil loss. The commonly used measures at present include engineering measures, biological measures and water storage and soil conservation tillage measures. The slope is one of the engineering measures. The slope is a slope surface with a certain slope formed on both sides of the roadbed. People often install slope consolidation devices on one side of the slope to reinforce the slope.

[0003] The prior art CN215367344U discloses a water and soil conservation device, which adopts a prefabricated stone plate combined with a prefabricated slope protection brick. The prefabricated stone plate is provided with a concrete column. The technical scheme solves the problem of poor stability and easy falling of the existing slope protection brick. The upper part of the concrete column is provided with a protection assembly. The protection assembly can provide warning protection for the roadside of the highway slope body, thereby avoiding the falling of passing pedestrians and vehicles and improving the safety of the device.

[0004] The prior art CN219671384U discloses a water and soil conservation slope care structure, which comprises a slope protection box and a top plate. The inner sides of the slope protection box are provided with a slope retaining device, which is rotatably installed between the inner sides of the top plate. An adjusting assembly is installed on the slope protection box, the top plate and the slope retaining device. The utility model realizes the adjustment of the angle of the slope retaining device according to the actual slope angle and shape, has high universality and strong practicability, can fix the soil close to the soil during use, avoids loosening during long-term use, and sets up a protective net and various baffles to avoid soil loss caused by rainwater erosion, thereby improving the water and soil conservation effect of the structure.

[0005] However, the prior art still has the problems of insufficient stability and limited anti-erosion effect. In the prior art, the fixing spikes are used to tightly insert the parts of the care structure into the slope soil, thereby achieving fixation. However, the fixation by the fixing spikes is not stable enough, and the overall structure is prone to displacement, which affects the care effect of the slope. When the rainwater erodes, the top slope soil is blocked by the first, second and third baffles, but when the baffles accumulate to a certain extent, the slope soil will still be severely eroded, and the water and soil conservation effect is not ideal.
