A Vegetation Restoration Structure for High and Steep Slopes

Abstract

The invention provides a high and steep slope vegetation restoration structure, the growth substrate is covered on the surface of the high and steep slope body, the reinforcement net is located in the growth substrate, the water blocking grooves are distributed on the growth substrate along the horizontal direction, and the seed germination substrate The longitudinal stripes are embedded in the growth matrix, and the seed germination holes are distributed on the microporous film according to the position of the seed germination matrix; Close to the bottom of the water blocking groove, the slope matrix of the restoration structure is stable, effectively preventing the soil or gravel on the slope from slipping, and its light weight is conducive to fixing the greening substrate, improving the germination rate of seeds, and increasing the coverage of vegetation The water blocking groove can prolong the residence time of natural rainfall or artificial water on the microporous film, further make the water fully infiltrate into the growth substrate, and avoid runoff loss and runoff damage to the growth substrate or growth substrate under high and steep slope conditions. Erosion of the seed germination substrate.

Description

technical field [0001] The invention belongs to the technical field of restoration and management of vegetation on high and steep slopes, and in particular relates to a restoration structure of vegetation on high and steep slopes. Background technique [0002] my country's geographical structure is complex, and high and steep slopes are widely distributed. They have the characteristics of large slopes and high slope heights. Generally speaking, it is difficult, the cycle is long, and the recovery effect is not ideal. [0003] At present, there are mainly the following types of vegetation management measures for high and steep slopes: [0004] (1) Thick-layer substrate greening structure: it is suitable for soil slopes, moderately weathered or weakly weathered rock slopes with a slope ratio not steeper than 1:1, and loose fragments with broken slopes and poor vegetation growth Rocky and unstable slopes containing large gravel. However, when the slope is steep, its defects w...

Problems solved by technology

However, when the slope is steep, its defects will be very obvious, such as the inability to overcome the height and steepness of the slope and the weight of the soil itself, and the inability to resist long-term torrential rain and scorching sun, eventually forming gully erosion, sheet erosion and even slope collapse. Causes secondary damage to the slope surface, which is very unfavorable for the fixation of the greening substrate, and is easily washed away by heavy rain, and the ability of soil fixation and water retention is poor

[0005] (2) Vegetation concrete spraying slope protection structure: it often uses stone or concrete masonry to build retaining walls and face protection, or adopts the method of spraying anchors to carry out fully enclosed protection for slopes. This traditional slope protection is Reject the rigid protection of green plants. Although this can prevent serious soil erosion, landslides, mudslides and other disasters caused by slope instability, it also brings serious environmental problems, such as visual pollution and ecological imbalance. Restricted by the angle and height of the slope, it cannot cover everything. In addition, the structure of spraying isolates the contact between the vegetation and the natural soil and rocks, resulting in a low seed germination rate, small vegetation coverage, and unstable plant roots. A series of problems such as lodging
