Cutter Suction Dredger Pumping A Pebble In The Qinhuangdao Port Coal Five

Cutter-suction dredger looses the soil to mix with the water by cutter, and pumps the mud by dredge pump. It becomes the universal ship in dredging works because it has the widest adaptation range to soil, great production capacity, high economic efficiency. It can finish excavation and discharge (dredging and reclamation) procedures together and works continuously.The core technology of cutter-suction dredger is to determine the pump running parameters according to construction conditions and determine the production capacity. The technology of pebble pumping discharge by cutter-suction dredger is complicated and the cases are less in practical project. Based on the dredging and reclamation project of the fifth stage Qinhuangdao harbor coal dock, according to boundary conditions such as construction condition, pumping discharge distance and etc. , and referring to previous construction experience and foreign advanced technology, the detailed design of dredge pump parameters is carried out. The working condition and productivity are also determined. The reason of problems occurring in pebble construction is analyzed, and the scheme and suggestion of solving the problem are also presented.
