摘要
为了确保内河向长江泄洪通道的顺畅,入江口附近江堤崩岸治理是十分必要的。提出抛石与主动钩连体抛护江堤方案,总结了江滩抛投工程特有的安全隐患注意事项。并结合抛投区域的复杂地理条件,重点分析抛投技术流程应用于长江(江苏段)崩岸治理工程中。根据现场抛投试验数据,提出块石与钩连体的水平漂距计算公式,得到工程段抛投体漂距为5.2~7.5 m,进而可选用12 m吊臂的起重机在5 m宽、10 m长的单元内进行抛投,经水下地形测试抛投效果良好,为类似工程提供参考。
In order to ensure the smooth discharge channel of the inland river to the Yangtze River,it is necessary to treat the embankment collapse near the mouth of the river.A scheme of protecting the river dike by riprap and active hook is put forward.The special cautions for the safety hidden danger of the river beach jettisonin project are summarized.Combined with the complex geographical conditions of the jettisonin area,the application of the jettisonin technology process in the Yangtze River(Jiangsu section)Bank Collapse Management Project is specially analyzed.According to the on-site jettisonin test data,the calculation formula of horizontal drift distance between the block rock and hook is put forward,and the drift distance of the jettisonin in the project section is 5.2~7.5 m.Furthermore,a crane with 12 m boom can be used for the jettisonin in the unit of 5 m wide and 10 m long.The jettisonin effect is good after the underwater terrain test,which provides reference for similar projects.
