Ecological slope protection, soil fixation and water retention construction method for concrete faced rock-fill dam

Abstract

The invention relates to an ecological slope protection, soil fixation and water retention construction method for a concrete faced rock-fill dam. The construction method mainly aims at the humus soilwater and soil loss mode of a rear dam slope of the rock-fill dam, and adopts a multifunctional structure layer, namely a bottom layer function area for filtering at the bottom, a middle layer function area for fixation at the middle and a surface layer function area for protection at the top. Water and soil loss is controlled and reduced by adopting a three-dimensional space method of filteringat the bottom, fixation at the middle and protection at the top, so that the soil fixation effect is achieved; aiming at the characteristics that humus soil of the rear dam slope of the rock-fill damis thin, water evaporation is fast and the water retention performance is poor, a special water retention material for the slope is specially added from an ecological slope protection base layer structure, water resources can be provided for plants in the continuous drought period, and the water resources are stored in the rainwater abundant period.

Description

technical field [0001] The invention belongs to the technical field of water conservancy and hydropower engineering, and in particular relates to a construction method for ecological slope protection of rockfill dams for soil stabilization and water conservation. Background technique [0002] With the development of market economy and the advancement of science and technology, local material dams are the trend of popularization and application of water conservancy industry projects. Combined with the national sustainable development strategy, the simultaneous design and construction of environmental ecological engineering and water conservancy projects is the highlight of the promotion and application of water conservancy projects.

Problems solved by technology

[0003] At present, most of the local material dams are face rockfill dams. The main body of face rockfill dams is formed by rolling stone materials, and the slope of the back dam is steep. If ecological grass planting needs to be paved with a certain thickness of loam, it is washed by rainwater, has no groundwater supply and Affected by objective factors such as large rockfill gaps on the slope surface, it is easy to cause a large amount of soil loss on the slope surface, poor soil water retention performance, and soil particles infiltrating into the dam body, etc., resulting in the lack of necessary growth substrates and water required for growth of vegetation.
