摘要
疏浚是川江航道治理最重要的措施之一。长期以来,川江航道治理产生的疏浚土未进行有益利用,简单粗放的疏浚土处理方式不仅造成泥土资源的浪费,还对生态环境造成二次污染。在分析川江航道疏浚土来源及特点的基础上,结合工程实际,探索疏浚土改善环境和工程利用的2种途径,提出表层砂卵石疏浚土上岸作为建筑材料、底层砂卵石及块石疏浚土构建生态涵养区的利用方案,获得良好的投资效益和生态效果,可为类似航道治理工程疏浚土利用及内河生态航道建设提供借鉴。
Dredging is one of the most important measures of the waterway improvement,which always produces tons of dredged materials while improving the waterway.For a long time,the dredged materials produced by the waterway improvement projects have not been re-utilized.The simple and rough disposal of the dredged materials is not only a waste of soil resources,but also a pollution to the ecological environment.Based on the analysis of the characteristics of dredged materials and the actual conditions of the waterway improvement project of the Chuanjiang River,this paper explores two ways of utilization of dredged materials for improving the environment and engineering utilization of dredged materials,and puts forward a plan for the utilization of surface sand pebble dredged materials as building materials,bottom sand pebble and block dredged materials for constructing ecological conservation areas,which has received good investment profits and ecological effects,and may serve as reference for the utilization of dredged materials and the construction of inland ecological waterways.
