海底管道充水铺设技术

Water Filling Laying Technology for Submarine Pipeline

在海底管道安装期,对裸置于海床上的管道,在波流等自然环境因素的作用和影响下,当依靠其自身重量不足以保持稳定时,充水铺设是解决问题的方法之一。文章主要从海底管道的稳定性、铺设可行性以及施工工艺三个方面对充水铺设方法进行了详细阐述,总结了此方法的优点和不足,并以渤海湾某海底管道为例,说明了此种方法的具体应用。

When a submarine pipeline can not maintain its stability if only relying on its own weight in the installation period under the action and influence of wave,current and other natural environmental factors,one of the methods to solve the problem is to fill water into the pipeline.This paper explains the method in detail from three aspects: pipeline stability,laying feasibility and construction technology,and summarizes the advantage and disadvantage of this method.Taking one submarine pipeline in Bohai Bay for example,it illustrates the specific application of this method.
