摘　　要：文章主要探讨城市河道生态疏浚治理施工技术。以深圳三溪河综合整治工程为例,从施工准备、脱水场地建设、药剂制备、管路及管袋安装、管袋充填、泥浆处理等方面,介绍了新工艺流程。此技术节能且灵活,采取闭环运行,通过绞吸船清理底泥,并加入化学物质,导入土工管袋,实现疏浚治理,促进了淤泥收集的有效管理,废水也达到农业灌溉标准,减少了施工对环境和水体的负面影响,该项目的成功应用,具有积极的推广价值。This paper mainly discusses the ecological dredging treatment construction technology for urban river channel.Taking Sanxi River comprehensive improvement engineering in Shenzhen as an example,the new process flow is introduced from the aspects of construction preparation,dewatering site construction,reagent preparation,pipeline and pipe bag installation,pipe bag filling,slurry treatment and so on.This technology is energy-saving and flexible.It adopts closed-loop operation,cleans the sediment through the cutter suction vessel,adds chemical substances,and imports the geotechnical pipe bag to realize the dredging treatment,which promotes the effective management of sludge collection and the wastewater also meet the agricultural irrigation standards,reducing the negative impact of construction on the environment and water bodies.The successful application of the project has positive promotion value.
