长江口深水航道疏浚吹填一体化施工工艺

摘要

针对长江口地区近年来出现的新圈围造地工程,因条件限制或成本控制不宜设置储泥坑的情况,通过长兴潜堤工程实例,介绍长江口深水航道疏浚吹填一体化施工工艺,对工艺中的疏浚施工、艏吹抛锚定位以及吹泥施工等关键技术进行重点阐述.该工艺无需设置中转储泥坑,疏浚土一次性吹填上岸,并用于造地成陆,在长江口地区应用效果较好.%For the Yangtze River Estuary area in recent years,some new reclamation projects cannot excavate the storage pit because of constraints or cost control.Through Changxing submerged breakwater engineering construction,we introduce the construction technology for integration of deep-water channel dredging and filling in the Yangtze River Estuary,and discuss the key technologies of dredging,anchoring and bowing.The construction technology does not need to set the storage pit,and the dredging soil could be pumped to the shore for land reclamation.It is very effective,resulting in a comprehensive benefit in the Yangtze River Estuary area.
