绞吸船超长距离多点吹填专项方案设计

Design of special construction scheme of extra-long distance and multi-point filling for cutter suction dredger

随着港口建设、航道维护、岛礁填筑等工程不断朝着更远吹距、更硬底质、更大挖深等复杂工况方向迈进,对疏浚装备选用、技术方案设计及施工组织都提出了更高的要求。针对东营港进港航道现场条件复杂、海况恶劣,且疏浚纳泥区分散、疏浚土输送距离远、成本控制难度大等问题,通过对超长距离多点吹填施工方案进行疏浚装备比选、管线冗余设计、输送能力计算和施工组合优化,设计了一套技术可行、安全环保、管理便捷、经济实用的绞吸船超长距离多点吹填专项组合施工方案,可为类似疏浚吹填工程提供借鉴。

As port construction, waterway maintenance, island reclamation and other projects continue to move towards the direction of longer blowing distance, harder bottom, larger digging depth and other complex conditions, higher requirements are put forward for dredging equipment selection, technical scheme design and construction organization.Regarding the complex site conditions of Dongying Port approach channel, poor sea conditions, scattered dredging area, long transport distance of dredged soil, difficult cost control and other problems, the comparison and selection of dredging equipment, pipeline redundancy design, transportation capacity calculation and construction combination optimization are carried out for the construction scheme of ultra-long distance multi-point dredging. A set of special combined construction scheme of extra-long distance multi-point dredging for cutter suction vessel is designed, which is technically feasible, safe, environmentally friendly, convenient and economical, and can provide reference for similar dredging and filling projects.
