Optimization of cutter suction dredger construction process for dredging project of general berths 27#～29#in Longkou Port Area of Yantai Port
The soil quality of the dredging project for the 27#～29#general berths in the Longkou Port Area of Yantai Port is mainly composed of cohesive soil mixed with a small amount of coarse sand.During the construction of this soil quality,the cutter suction dredger is affected by clay pilling and viscosity,which can easily lead to pipe blockage,cutter sticking,and transportation difficulties.The fluctuation of key parameters in the construction operation is large,and the operators control are difficult,resulting in low average production efficiency.This article focuses on the excavation and transportation analysis of cutter suction dredger,determining key construction parameters,optimizing construction processes,and guiding operators in construction.The optimized construction process has increased the construction capacity of the cutter suction dredger for the general berths 27#～29#in the Longkou Port Area of Yantai Port by more than 20%,saving construction costs.
