Problems solved by technology

While meeting the functional requirements of slope protection, it also has a stress effect on the ecosystems of rivers, lakes and other water areas, blocking the connection between water bodies and near-shore land soil, and destroying the original ecosystems of rivers and lakes. Although the soil erosion of the slope has been prevented to a certain extent, plants cannot grow on the slope, which is not in harmony with the surrounding natural environment, and is contrary to the current trend of harmonious development between man and nature.

Abstract

The invention belongs to the field of ecological restoration engineering, and discloses a hard river channel side slope ecological slope protection system and a construction method thereof. The systemcomprises multiple anchor rods, a bidirectional geogrid, a base material cushion layer, an anti-corrosion permeation control layer, a vegetative coiled material and a nutrient base material. The multiple anchor rods are arranged on a river channel side slope, evenly arranged on the slope surface at intervals and used for fixing the bidirectional geogrid and the vegetative coiled material where nutrient base material is poured; the bidirectional geogrid is arranged on the anchor rods, 1cm-3cm away from the slope surface and used for enhancing the integrity of the base material cushion layer; the base material cushion layer is arranged on the slope surface and used for providing nutrition for planted plants; the anti-corrosion permeation control layer is arranged on the surface of the basematerial cushion layer, is formed by consolidating an anti-corrosion permeation control composite material and the base material cushion layer and has water retention and fertilizer retention functions; the vegetative coiled material is arranged on the anti-corrosion permeation control layer and fixed on the anchor rods and is used for accommodating the nutrient base material; and the nutrient base material is arranged in the vegetative coiled material and used for supplying nutrition to the planted plants. The system can promote plant growth and realize ecological restoration of the hard river channel side slope.

Description

technical field [0001] The invention relates to an ecological slope protection system for hard river slopes and a construction method thereof, belonging to the field of ecological restoration engineering. Background technique [0002] In the process of traditional water conservancy project construction and treatment, due to the constraints of concepts and technologies, river channel construction is mainly satisfied with the realization of traditional functional requirements such as flood discharge, water storage, drainage, and irrigation, and does not pay attention to the protection and restoration of the ecological environment. The slope protection structure mostly adopts hard slope protection such as mortar or dry block stone slope protection, cast-in-place concrete slope protection, and prefabricated concrete block slope protection. While meeting the functional requirements of slope protection, it also has a stress effect on the ecosystem of rivers, lakes and other water ...
