改性淤泥-植生混凝土生态护坡技术在工程中的应用——以高邮灌区为例

Application of modified silt-vegetated concrete ecological slope protection technology on engineering:taking Gaoyou Irrigation District as an example

针对传统护坡技术生态效应差的问题,结合室内试验和现场示范,探究以改性淤泥和植生混凝土两种护坡材料相结合的生态护坡技术,建设兼具输水性、防渗性及保水性的生态可植生渠道。以江苏省高邮灌区生态护坡建设工程为例,明确护坡技术参数并进行现场施工。结果表明:经过3个月的现场示范,植物种子发芽情况良好,坡面稳固。即使在多雨时节,植物长势依然良好,且坡面未出现坍塌情况。和传统护坡方式相比,改性淤泥-植生混凝土生态护坡方式在兼具生态优势的基础上,造价估算要低13.63%,经济效益显著,具有较好的应用发展前景。

Aiming at the problem of poor ecological effect of traditional slope protection technology,combining indoor tests and field demonstrations,the ecological slope protection technology combining modified silt and vegetated concrete as slope protection materials is explored,and an ecological vegetation channel with water conveyance,anti-seepage,and water retention properties is constructed.Taking the ecological slope protection construction project in Gaoyou Irrigation District of Jiangsu Province as an example,the technical parameters of the slope protection are clarified and on-site construction is carried out.The results showed that the plant seeds germinated well and the slopes were firm after a 3-month field demonstration.Even in the rainy season,the plants grew well and there was no collapse on the slope.Compared with the traditional slope protection method,the modified silt-vegetated concrete ecological slope protection method,on the basis of ecological advantages,the cost is estimated to be 13.63%lower,the economic benefits are significant,and has a better application and development prospects.
