城市河道清淤疏浚环境保护技术措施探索与实践

Exploration and practice of environmental protection technical measures for dredging of urban river course

为有效避免清淤疏浚施工对河流水质、大气环境、城市道路环境的污染和影响,对河道两岸绿地、园林和景观的损害,通过对绞吸式挖泥船进行技术改造和运行控制,实现低扰动清淤疏浚施工作业,通过采用疏浚泥浆脱水固结一体化处理技术,实现疏浚泥浆输送、脱水一次完成。两者联合运用,大幅减少了施工临时占地,实现了清洁、绿色施工生产。

In order to effectively avoid the pollution and influence of dredging construction on river water quality,atmospheric environment and urban road construction environment,as well as the damage thereof on green space,landscape and scenery on both banks of the river,low disturbance dredging construction work is realized through the technical transformation and operational control of cutter-suction dredger.The dredged mud transportation and dehydration are completed in one time through the adoption of dredged mud dehydration consolidation integration processing technology.Two methods are applied together to greatly reduce the construction temporary covered area,and realize clean green construction and production.
