摘要
目前国内河道整治中常用的底泥处理方法主要有堆场处理、固化处理,在处理过程中均需设置底泥堆放场进行底泥临时堆放,如何对底泥堆放场进行场地环保防护,防止二次污染显得尤为重要。文章依托深圳市光明区某河道治理工程,在不能使用混凝土对场地硬化前提下,提出了使用铺设复合土工膜、沙袋和反滤土工布3层防护防渗措施对底泥堆放场进行防护,达到减少工程建设造成的二次污染、土地损毁和水土流失,恢复其生产能力、利用功能目的。
At present,the common methods of sediment treatment in domestic river regulation mainly include yard treatment and solidification treatment.During the treatment process,it is necessary to set up a sediment yard for temporary storage of sediment.How to protect the site environment and prevent secondary pollution is particularly important.Based on a river treatment project in Guangming District of Shenzhen City,this paper proposes to protect the bottom mud dump yard by laying three layers of composite geomembrane,sand bag and reverse-filtration geotextile,without using concrete to harden the site,so as to reduce secondary pollution,land damage and water and soil loss caused by the project construction,and to restore its production capacity and utilization function.
