污染底泥精确疏浚技术

Technology for Accurate Dredging of Contaminated Subsoil

为提高我国浅水湖泊环保疏浚质量,实现环保挖泥精确疏浚的设计思想而研发环保疏浚仪表。该设计采用高精度定位及挖深控制技术,通过示范工程的验证,使疏浚后精度控制在<10cm范围内。通过对关键技术的研究,提高环保疏浚精度,从而保证在最大程度清除污染底泥的同时,减小对未污染土的破坏。

To improve the quality of environmental dredging in shallow lakes in China and to realize the design ideas of development of instruments for environmental dredging to achieve accurate dredging in environmental dredging operations,high precision positioning and dredging-depth controlling techniques,verified by demonstration dredging,were adopted to control the post-dredging accuracy within <10 cm.Researches on key techniques were conducted to improve the accuracy of environmental dredging,thus ensuring that,while the contaminated subsoil was removed to the maximun,the disturbance of the uncontaminated subsoil was minimized.
