摘要
混凝土生态护岸,就是在河道岸坡浇筑大孔生态混凝土,在混凝土表面栽种草皮,形成绿色植被。为了探讨混凝土生态护岸的工程效果,在花园口东4km的黄河南岸进行了100m2的混凝土生态护岸现场试验。结果发现,生态混凝土板块阻止了雨水对岸坡的冲蚀,砖砌体挡墙和堆石阻止了河水对岸坡的冲刷和淘洗,下坡面铺设的土工布防止了退水引起的管涌和流土破坏,起到了保护堤防安全稳定的工程效果;草皮栽种2个月后生长茂密,基本覆盖了堤防坡面,形成了绿色植被,达到了绿化岸坡、生态护坡的工程效果。采用混凝土生态护岸,可以把河流岸坡硬化和绿化结合起来,保持河流生态系统的可持续发展。
The revetment with eco-eoncrete is pouring the macroporous eco-conerete in the river bank slope, planting in the concrete surface, and forming green vegetation. To investigate the effect of the concrete riverbank protection engineering, the 100 m2 concrete revetment ecological test was carried out in the garden 4 km east of the mouth of the south bank of the Yellow River. It is found that the coo-concrete slabs prevent the erosion of rain on the bank slope, brick masonry retaining wall and rock prevent the erosion of the river bank slope and panning, next slope laying of geotextile fabric prevents piping and flow caused by the withdrawal of water soil destruction, playing a protective role in the dike security and stability engineering; turf plants will grow well in 2 months, basically covering the embankment slope and forming a green vegetation to reach the green bank slope, slope protection of the ecological effect. Adopting concrete riverbank protection, we can combine hardening and greening of the river bank slope to maintain the sustainable development of the river ecosystem.
