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. In order to prevent the occurrence of the above geological disasters, slope treatment is required , while the protection structure of the existing traditional slope prot...

[0030] A construction method for ecological slope protection of concrete prefabricated blocks in reservoir engineering;

[0031] The specific operation steps are as follows:

[0032] S1. Reservoir slope pretreatment: clean up the vegetation junction above the opening line of the dam slope, and clean up the width of 1.5m-2m (adjust the width according to the actual situation on site). Weeds, fallen leaves and dead branches, floating soil and pumice, etc. At the same time, potholes on the slope of the dam body are artificially filled and watered and tamped. Guarantee of deviations between them, reducing the difficulty of operation during the installation of concrete prefabricated blocks in the later stage;

[0033] S2. Set up water channels. After the slope of the dam body is leveled, it is necessary to set up cut-off drainage ditches at the junction of the ...
