长江深水砂被铺设施工工艺

因与先期软体排护底工程有重合区域,针对区域内存在块石及透水框架的问题,为避免对铺设的软体排造成破坏,在现有铺排船铺设软体排的基础上,采用铺排船进行深水砂被铺设处理,达到了阻隔碎石垫层、抛石等挤入淤泥和部分的水平排水的目的。     

长江口新浏河沙护滩堤的防护施工技术

新浏河沙护滩及南沙头通道潜堤工程是长江口深水航道治理工程的重要组成部分.受不利河势变化影响,其整治建筑物局部余排外侧冲刷持续发展,影响了结构的安全稳定.为确保治理效果而实施了本次防护工程.在总结长江口深水航道治理工程经验的基础上,通过对现场水流条件分析及典型施工,在船机设备、软体排加工及施工工艺等方面进行了一系列优化改进,首次在长江口水深30m以上的深水区成功实施了砂袋抛填及软体排铺设,满足了设计要求.     

超短基线软体排深水水下定位检测系统设计思路

结合长江南京以下12.5 m深水航道一期工程,根据深水、大流速工况,提出了超短基线软体排深水水下定位系统的设计思路,经过系统开发、测试完成了设计,通过应用实现了软体排在深水条件下铺设定位的可视化,实时调整铺排船作业时的工作状态,确保排体铺设准确。
