长江南京以下12.5m深水航道二期工程深水充灌袋装砂堤心施工工艺

摘要

Based on the 12.5 m deep-water channel construction phase Ⅱ of the Yangtze River below Nanjing city,first successful application of construction technology of deep water filling bagged sand dike core of the deepest depth of-35 m.By optimizing the filling sand bags sewing process,improving the filling sand bags laying process,we realized the application of filling bagged sand dike core construction technology in deepwater construction.The construction technology has improved construction efficiency,enhanced the levee molding accuracy,reduced the consumption coefficient,to ensure project quality.%长江南京以下12.5 m深水航道二期工程,首次成功应用深水充灌袋装砂堤心施工工艺,最深施工水深-35 m.通过优化充灌砂袋缝制工艺,完善充灌袋装砂铺设流程,实现了充灌袋装砂堤心施工工艺在深水施工中的应用.深水充灌袋装砂堤心施工工艺,提高了施工效率,提升了堤身成型精度,降低了消耗系数,确保了工程质量.
