High-steep rock slope ecological restoration system and implementation method thereof

Abstract

The invention belongs to the field of slope ecological restoration and discloses a high-steep rock slope ecological restoration system. The system comprises a water storage type drainage ditch, a solar automatic irrigation system and an erosion-resistant external soil reconstruction system. The water storage type drainage ditch includes a drainage ditch, a water storage cavity and a rainwater filtering grating. The solar energy automatic irrigation system comprises a solar automatic control system, a water pipe, a water pump, and a moistube. The anti-scouring external soil reconstruction system comprises a flexible ecological bar, a U-shaped anchor rod, a high-strength steel wire protection net, an external soil substrate and a plant seed layer. The invention also includes an implementation method of the system. Through the implementation of the system, an erosion-resistant external soil matrix structure can be established on a rock slope, the vegetation system of an indigenous plant is used, with the addition of the automatic irrigation system with solar control, the ecological vegetation of the high-steep rock slope can be effectively reconstructed, and the purpose of ecologicalrestoration is achieved.

Description

technical field [0001] The invention belongs to the field of slope ecological restoration, in particular to the ecological restoration of high and steep rocky slopes. Background technique [0002] High and steep rock slopes refer to rock slopes with a slope greater than 60° and a height greater than 15m, which often appear in mining, quarry, water conservancy and hydropower projects. Due to the lack of basic soil conditions for plant growth on high and steep rocky slopes, solving the problem of foreign soil attachment is the key point of its ecological restoration. The existing technologies mainly include the construction of planting troughs, frame beams and spraying of foreign soil on hanging nets Three types, the current mainstream development trend is the use of hanging net soil spraying technology, which has the advantages of simple structure, convenient construction, low cost, and good ecological restoration effect, but the hanging net guest soil spraying technology is ...

Problems solved by technology

Due to the lack of basic soil conditions for plant growth on high and steep rocky slopes, solving the problem of foreign soil attachment is the key point of its ecological restoration. The existing technologies mainly include the construction of planting troughs, frame beams and spraying of foreign soil on hanging nets Three types, the current mainstream development trend is the use of hanging net soil spraying technology, which has the advantages of simple structure, convenient construction, low cost, and good ecological restoration effect, but the hanging net guest soil spraying technology is applied to high and steep edges There are some problems in slope fashion, mainly reflected in the easy detachment of foreign soil matrix and the difficulty of watering and maintenance, which seriously limit the popularization and use of this technology

The ultimate goal of ecological restoration is to realize the natural succession of slope vegetation, so the selection of plants is particularly important. However, the current ecological restoration of high and steep slopes mostly stays in the regreening stage, with single plant species, easy vegetation degradation, and human-induced degradation. The phenomenon of long-term intensive conservation is completely different from the original intention of ecological restoration
