摘　　要：随着城市经济的快速发展,解决城市河道的污染、恢复河道的生态,是城市可持续发展过程中亟待解决的问题。近几年来,在上海市河道整治中,除了采用抓斗式挖泥船等施工工艺之外,结合环境保护等因素,部分河道整治采用泵吸带式脱水疏浚施工工艺进行试点,取得一定成效。以上海市徐汇区漕河泾港污染底泥清除工程为例,通过泵吸带式脱水疏浚与抓斗式挖泥船等“传统”疏浚施工法,从施工工艺及经济性两方面进行比较,从而论证泵吸带式脱水疏浚施工工艺,在环境保护、施工成本、底泥减量化及资源利用等方面具有优势,更具推广和实用价值。With the rapid development of urban economy, solving the pollution of urban rivers and restoring the ecology of rivers is an urgent problem to be solved in the process of sustainable urban development. In recent years, in the river improvement of Shanghai, in addition to the construction process such as grab dredgers, combined with environmental protection and other factors, some river courses have been piloted by pumping belt dewatering and dredging construction technology, and achieved certain results. Taking the pollution sediment removal project of Caohejing Port in Xuhui District of Shanghai as an example, the traditional dredging construction methods such as pumping belt dewatering dredging and grab dredger are compared in terms of construction technology and economy. Demonstrate the pump suction-type dewatering and dredging construction technology, which has advantages in environmental protection, construction cost, sediment reduction and resource utilization, and has more promotion and practical value.
