Thick-layer base material soil dressing spray-seeding structure suitable for ecological restoration of high and steep slope and construction method thereof

Abstract

The invention discloses a thick-layer base material soil dressing spray-seeding structure suitable for ecological restoration of a high and steep slope and a construction method thereof. The spray-seeding structure comprises a first layer of matrix soil, a plant fiber mat, a second layer of matrix soil, a vegetation layer and geotechnical cloth, wherein the first layer of matrix soil, the plant fiber mat, the second layer of matrix soil, the vegetation layer and the geotechnical cloth are laid on the surface of the slope in sequence, the vegetation layer comprises soil dressing matrixes and vegetation seeds, the soil dressing matrixes take bottom mud compost as raw materials, the plant fiber mat and the geotechnical cloth are prepared from biodegradable materials, and a reinforcing structure and a planting groove are arranged, so that the soil fixation stability of the side slope is increased. According to the thick-layer base material soil dressing spray-seeding structure, a composite structure is formed by adopting multiple layers of base materials and covers the side slope, so that the problems of the side slope stability of high and steep slope dressing soil and the new environment burden caused by the side slope stability are effectively solved.

Description

technical field [0001] The invention belongs to the technical field of slope ecological protection, and in particular relates to a thick-layer substrate guest soil spraying structure and a construction method suitable for ecological restoration of high and steep slopes. Background technique [0002] In recent years, with the continuous development of the economy, the construction of roads, railways and mountainous areas have been continuously increased, and the mining of mines has been deepened, resulting in a large number of high and steep slopes caused by human factors. The exposed high and steep slopes not only affect the environment and landscape, but are also prone to geological disasters such as collapses and landslides, causing potential safety hazards. The protection of high and steep slopes has always been an engineering problem. [0003] Although traditional engineering reinforcement measures such as shotcrete anchors, cement skeletons, and retaining walls can quic...

AI Technical Summary

Problems solved by technology

However, the matrix required for guest soil spraying usually requires a large amount of loam, which is easy to form new excavations and exposed areas.

At the same time, due to the needs of plant nutrients and slope soil stabilization, it is often necessary to add fertilizers such as chemical fertilizers and curing agents such as cement and lime to increase the fertility and strength of the soil matrix, which will cause a certain burden on the slope soil environment and slope protection plants.

For high and steep slopes, guest soil spraying is also prone to problems such as soil fixation and poor water retention capacity.
