Qingdao Qianwan Three # 1-2 Berth Dredging Construction Technology And Explore

Qianwan locates at the inner of Jiaozhou Bay in Qingdao. It owns structures in superior condition and rather good natural conditions for port engineering. With rapid development of local economy, the port now plays an increasing important and predominant role. However, its development oriented to the large-scale requires deeper navigation water depth, while the complicated geologic condition severely affects dredger capability, and delays the dredging and construction of the port.According to the 3-phase application conditions and the geological character of Qianwan port, it is necessary to choose right dredging instrument and determine the real production ability of dredgers by more theoretical analysis. Especially when cutter suction dredger is used, its production capability can be worked out by mud-pump and piping theory, as all the dredgers can do their best to keep the construction in schedule. Concerned to boat execution management, boats are arranged flexibly to fit the varying construction conditions and working characters of themselves, which will definitely benefit the dredger productivity. Different construction fields correspond to different dredging methods, so this paper, combining past experience of management and construction, presents how to reinforce and focus on the technical management and experience accumulation. It will make a certain sense referring to the dredging execution management.
