长江南京段砂袋深水护岸施工技术

Construction of Sandbag Deep Revetment in Nanjing Section of Yangtze River

针对长江南京大胜关岸段江堤存在的岸坡坍塌失稳危险,采用常规护岸形式如抛石、梢料、混凝土排等在环境、造价及施工效率等方面存在弊端。介绍了一种新型砂袋护岸技术,分别从设计、施工、检测等方面阐述了该技术的特点。工程应用实践证明,该技术可就地取材、节约资源,护岸整体性好,抗冲刷能力强,结构稳定,造价经济,施工效率高。

The Dashengguan in Nanjing section of Yangtze River exist collapse risk of embankment. However, the conventional revetment types such as rock rip-rap, brush and concrete have some disadvantages in environment, cost, construction efficiency etc. In view of this, a new type sandbag revetment technology is introduced. The technical characteristics are described from the aspects of design, construction and inspection. It has been proved from practice that the construction technology can effectively reduce costs and ensure project quality and shorten the construction period by using local raw materials, the sandbag revetment has good capability of anti-scouring and structural stability, it can strengthen working efficiency with low cost.
