Ecological slope protection, soil fixation and water retention construction method for concrete faced rock-fill dam
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.
本发明是一种面板堆石坝生态护坡固土保水施工方法，主要针对堆石坝后坝坡腐殖土水土流失方式，采用多功能结构层，即，底层功能区（下滤）—中间层功能区（中固）—表层功能区（上防）。通过采取下滤、中固和上防的三维空间方法控制和减少水土流失，实现固土效果；针对堆石坝后坝坡腐殖土较薄，水份蒸发快，保水性能差的特点，特从生态护坡基层结构加入边坡专用保水材料，在持续干旱的时段中可以为植物提供水资源，在雨水充沛时段存储水资源。
