【摘要】 本文通过对传统河道清淤工艺局限性的分析,阐述了河道湿式生态清淤工艺原理及适用范围。结合东引运河清淤工程中的工艺运用情况,有针对性地对河涌湖泊淤泥的清挖与输送、物理筛分施工工艺进行优化和改进。该清淤工艺通过自制铰刀防护罩和筛分滚筒,避免了铰刀和岸坡基础、各种管线等直接接触,提高了清淤的安全性和淤泥初始筛分效率。更多还原

【Abstract】 River wet ecological dredging techndogy principle and scope of application are expounded in the paper through analyzing limitations of traditional channel dredging technology. Technology application situation during east canal dredging project is combined for optimizing and improving silt digging and transportation as well as physical screening construction process of river burst lake in a targeted mode. Direct contact of reamer with bank foundation,various pipelines,etc. is avoided by homemade reamer shield and sieving drum,thereby the dredging technology improving the security of desilting and mud initial screening efficiency.更多还原
