Try in make clear, hydraulic pressure shovels dredger, grab bucket to shovel dredger construction efficiency instead instead taller, dredge of dredger of grab bucket type shovels type dredger to affect degree small; to wring dredger suction type to water environment than turning over, contain a lot ofas a result of bottom mud sundry, suction inlet jams extremely easily, apply to; of dredge of mud of Suzhou river bottom to undertake to groovy grab bucket environmental protection is transformed hard, the influence of earth of hourglass of leakage of the grab bucket in reducing dredge process significantly to water system water quality, be worth promotion application.

中试表明，液压反铲挖泥船、抓斗反铲挖泥船施工效率较高，抓斗式挖泥船疏浚比反铲式挖泥船对水环境影响程度小；绞吸式挖泥船，由于底泥富含杂物，吸口极易堵塞，难以适用于苏州河底泥疏浚；对常规抓斗进行环保改造，显著减少疏浚过程中抓斗漏水漏土对水体水质的影响，值得推广应用。
