Abstract:The traditional hydraulic reclamation has the problems of unevenness and serious ponding.Combining with the example of dredger fill construction of hydraulic reclamation and term II tender I area A2 in polder area of Cangnan County,we determine the fill height by timely energetic calculation of fill elevation,and adopt inlet pipe technology,separate layer dredger fill,decentralize arrangement of gates and other effective methods to ensure acceptance elevation,blowing and filing degree and no ponding in dredger fill area of various fill branch.The measures can shorten emission distance,decrease cost,alleviate cofferdam safety pressure and ensure the fill quality.
