摘要
针对马来西亚关丹新深水港疏浚工程抓斗船及泵吸船施工码头前沿狭窄水域浮泥施工效率低、施工工艺复杂的情况,提出采用平板驳辅助耙吸挖泥船施工工艺,通过将平板驳与耙吸船进行绑靠,使平板驳成为耙吸挖泥船与码头水工建筑物之间的缓冲。实践结果表明,该工艺有效规避了耙吸挖泥船近岸作业可能带来的碰撞风险,使耙吸挖泥船在码头前沿近距离施工成为可能,充分发挥了耙吸挖泥船大泥泵施工的优势,简化了施工工艺,大幅提高此类区域施工效率,可为类似工程提供借鉴。
The traditional method to deploy grab dredger pump barge to remove the fluid mud at the narrow area like wharf front,is complicated and lack of efficiency.In order to solve these problems occurred during implementation of the New Deep Water Terminal Dredging Project,Kuantan Port,Pahang,a new method known as utilizing flat-bottom barge to assist TSHD in dredging the fluid mud at the wharf frontage is introduced.The results show that by deploying flat-bottom barge between TSHD and the wharf front area,mooring the TSHD along the barge,the barge will work as a buffer to prevent the TSHD from crashing the wharf structure,which enables the TSHD to take advantage of its large-power pump to remove the fluid mud at the wharf front area.This method simplifies the operating procedures and significantly enhances the dredging efficiency at such an area,so it may serve as reference for similar projects.
