摘要
Abstract
As an inevitable technical problem,the cofferdam closure gap is more difficult to be closed by adopting the traditional construction process of sea reclamation,larger cofferdam area leads to more severe problem.Based on the traditional construction process,the closure gap shall be closed before sea reclamation,which prevents ocean from pollution,but results in a huge impact on the cofferdam closure gap under internal/external water flow pressure.The above construction requires the optimum combination of time,place and staff,is characterized with low efficiency and high failure ratio.In the case,the construction process was improved by setting up multi-level anti-fouling curtains combined with sea reclamation and cofferdam construction.The new measure reduced internal/external water flow pressure while closing the gap,and basically decreased the difficulty in closing the gap.关键词
