摘要
针对我国基础工程建设过程中因对地理形貌和植被造成毁坏而引起的地域生态环境失调等问题,进行兼具生态保护和护坡功能的生态植草混凝土及其施工技术研究。采用低碱度特种材料、大粒径骨料和优化配合比设计等方法,制备强度≥7.0 MPa、孔隙率≥30%、pH值≤9.0的生态植草混凝土,满足植物生长的基本要求。在室内试验和模型试验的基础上,依托株洲市清水塘老工业区产业新城整体开发PPP工程,确定了生态植草混凝土关键施工技术,并成功应用于边坡工程,边坡治理后的90 d植被覆盖率为95.3%,有效解决了滑坡隐患和绿化问题。
In response to the imbalance of the regional ecological environment due to the destruction of the original geographical features and vegetation in the process of basic engineering construction in China in recent years,we research the ecological grass-planting concrete and its construction technology with both ecological protection and slope protection functions.Using low-alkalinity special materials,large-size aggregates,and optimized mix design methods,we make the ecological grass-planting concrete with strength≥7.0 MPa,porosity≥30%,and alkalinity pH≤9.0 to meet the basic requirements of the plant growth.Based on the indoor test and model test,and relying on the overall development of the PPP project in the industrial new city of Qingshuitang Old Industrial Zone in Zhuzhou City,we determined the key construction technology of ecological grass-planting concrete and successfully applied it to the slope engineering.The 90-day vegetation coverage rate after slope treatment was 95.3%,which effectively solved the hidden dangers of landslides and greening problems.
