Reservoir engineering concrete precast block ecological slope protection construction method

Abstract

The invention relates to the technical field of reservoir slope protection construction, in particular to a reservoir engineering concrete precast block ecological slope protection construction method. The reservoir engineering concrete precast block ecological slope protection construction method comprises the following steps that S1, the reservoir slope surface is pretreated; S2, water channels are arranged; S3, foot protection construction is carried out; S4, geotechnical cloth is laid; S5, gravel layers are laid; S6, precast concrete blocks are laid; S7, spray planting construction is carried out; S8, non-woven fabric covering is carried out; and S9, watering maintenance is carried out. According to the reservoir engineering concrete precast block ecological slope protection construction method, slope protection plants and the precast concrete blocks are adopted to perform double ecological protection on a slope, material exchange between soil and water is achieved, and a food chain of an ecological system on the slope protection is maintained; meanwhile, the slope protection plants have a good protection effect on the slope surface of a dam body, and direct impact of water flow on the slope surface of the dam body is avoided; and meanwhile, the greening coverage rate of the slope body reaches 95% or above, the ecological environment and landscape are improved, and long-term continuous ecological slope protection can be achieved.

Description

technical field [0001] The invention belongs to the technical field of reservoir slope protection construction, and in particular relates to an ecological slope protection construction method of concrete prefabricated blocks for reservoir engineering. Background technique [0002] A dam is a water-retaining structure that intercepts the water flow of a river channel to raise the water level or regulate the flow. It can form a reservoir, raise the water level, adjust the runoff, and concentrate the water head. It is used for flood control, water supply, irrigation, hydroelectric power generation, and improvement of shipping. The slope formed on the side facing the water surface, generally in rainy days or strong vibrations, often occurs geological disasters such as landslides, collapses, swelling or spalling.

[0002] A dam is a water-retaining structure that intercepts the water flow of a river channel to raise the water level or regulate the flow. It can form a reservoir, raise the water level, adjust the runoff, and concentrate the water head. It is used for flood control, water supply, irrigation, hydroelectric power generation, and improvement of shipping. The slope formed on the side facing the water surface, generally in rainy days or strong vibrations, often occurs geological disasters such as landslides, collapses, swelling or spalling. In order to prevent the occurrence of the above geological disasters, slope treatment is required , while the protection structure of the existing traditional slope protection is to close the entire slope surface, which isolates the material exchange between the soil and the water body, so that the organisms that originally grew on the slope cannot continue to survive, and the food chain of the ecosystem is broken. The organisms in the soil and water lose their living environment, and the entire slope structure is prone to soil erosion under the erosion of the water flow, which affects the stability of the slope of the reservoir dam
