| Abstract: | When dredging hard clay by the trailing suction hopper dredger,there has some problems such as draghead blockage,cavitation and low production.This paper mainly introduces the dredging construction method for the stiff clay Bayuquan port 250 000 t channel by the trailing suction hopper dredger with plough teeth and soft grid,which effectively solves the problems of draghead blockage and cavitation,and raise the comprehensive production capacity by more than 60%. |
