摘　　要：在海洋工程中,经常涉及近岸端的施工作业,如管线登陆、栈桥施工等。但近岸区域受水流、周边环境、海床泥质影响,容易聚集浮泥。在这些区域进行的潜水作业效率低、风险大,甚至需要配备特殊的潜水面罩或头盔。介绍了一种可用于该环境的水下沉箱,通过创建隔离区域,配合吸泥设备,为潜水员水下作业提供一个相对可控、安全的作业环境。结合行业安全指南、标准要求以及环境特点,对水下沉箱的应用进行了简述,并介绍了水下沉箱在某项目中的应用。In marine engineering,construction operations at the near shore were often involved,such as pipeline landing,trestle bridge construction,etc.However,near-shore areas were affected by currents,surrounding environment,and mud on the seabed,which tended to accumulate floating mud.Diving operations in these areas were inefficient and risky,and even required special diving masks or helmets.An underwater caisson that could be used in this environment was introduced.By creating an isolation area and cooperating with mud suction equipment,it provided a relatively controllable and safe operating environment for divers underwater operations.Combined with industry safety guidelines,standard requirements and environmental characteristics,the application of underwater caisson was briefly described,and the application of underwater caisson in a project was introduced.
