通过鹤大高速公路工程生态敏感段湿地路基修筑关键技术应用,如采取CFG工法桩、碎石褥垫层、横向碎石盲沟、波纹钢管、EPS块等简单工艺,以及新技术、新材料的应用,研究解决高速公路路基安全性与生态湿地保护之间的矛盾。在确保路基安全稳定的前提下,加强地表水流通,保护地下根系水系连通,采取适当的生态湿地补偿技术,减少对生态湿地系统平衡的影响,对我国生态敏感路段湿地路基修筑技术进行推广应用。
Through the application of key technologies in wetland subgrade construction of the ecological sensitive section of Crane Highway Engineering, such as CFG pile, gravel cushion, horizontal blind gravel ditch, corrugated steel pipe, EPS block and other simple techniques as well as new technologies, new materials Application, research to solve the contradiction between highway safety and ecological wetland protection. On the premise of ensuring the safety and stability of embankment, the project will strengthen the circulation of surface water, protect the underground water system, and adopt appropriate ecological wetland compensation technology to reduce the impact on the ecosystem wetland system. The construction technology of wetland subgrade in ecologically sensitive section of China will be popularized and applied.
