接力泵船在连云港30万吨级航道疏浚硬质土中的应用

Application of floating booster station on dredged hard soil of 300 000-ton waterway project in Lianyungang Port

针对连云港30万吨级航道一期疏浚工程徐圩航道施工遇到的钙化结核物、黏土等问题,采用绞吸式挖泥船+接力泵船串联工艺施工,较好地解决了在吹距长、标高深、土质硬等不利条件下吹填上陆的施工难题,取得了较好的经济社会效益。

For the calcium compound and clay problems in the Xuwei waterway construction of the phase I dredging project of the 300 000-ton waterway in Lianyungang Port, we used the tandem process construction of floating booster station combined with cutter suction dredger. It solved the problems of long distance blowing, deep elevation and hard soil in the land reclamation construction, and can achieve good economic and social benefits.
