Experiment and Application of Vegetation Concrete in High and Steep Rocky Slopes
The Nanshan District Qianhai Road(Mianshan Road-Mawan Avenue)Project is located at the foot of the current Xiaonan Mountain.It is necessary to remove the stones at the foot of the Xiaonan Mountain slope to form a roadbed.The slope rock is mainly slightly weathered granite.To reduce the excavation face,the rock-slope ratio is 1:0.2,and the highest slope is about 45 m,belonging to a high and steep rocky slope.In order to implement the development concept that"Green mountains and clear waters are as valuable as gold and silver"and return Xiaonan Mountain a complete mountain forest,the vegetation concrete restoration technology is adopted.For this project,the ratio test of vegetation concrete and the screening test of plant seeds are carried out.Finally,a set of optimal proportions of vegetated concrete and species with good growth are selected.At present,after two and a half years of natural growth,the construction of vegetation habitats on high and steep rocky slopes has been basically achieved,and the ecological restoration effect is good,which can provide the references for similar projects.
