摘要
传统水利工程排水对原始生态河道造成难以恢复的破坏,阻隔了河流与生态陆地的水循环。本文介绍了植草混凝土的制备原理与其各种性能的测定方法,并且设计了植草混凝土的配合比方案,分析了能够影响植草混凝土的孔隙率、抗冲刷强度、抗压、抗折等性能的各种因素,获得植草混凝土的最佳配合比方案。在最佳配合比方案下,对植草混凝土进行植生试验,发现植物能够很好地生长在植草混凝土护坡上,说明该配合比方案符合小河流治理的相关性能指标要求,为小河流治理提供科学依据。
Drainage of traditional water conservancy projects leads to irreduciable damage to original ecological river channels. Water cycle between river and ecological land is blocked. In the paper,the preparation principle of hermophytic concrete and measurement methods of various performances are introduced. The mixing ratio plan of hermophytic concrete is designed. Various factors affecting hermophytic concrete porosity,anti-scouring strength,compressive strength,flexural performance,etc. are analyzed. The optimum mixing ratio plans of hermophytic concrete are obtained. And hermophytic concrete undergoes a plant-growing test. It is discovered that plants can well grow on the plant concrete slope. It is obvious that the mixing ratio plan is consistent with relevant performance index of the small river governance,thereby providing scientific basis for small river control.
