大型自航耙吸式挖泥船深水防波堤堤心砂抛填及理坡成型施工应用

Application of Sand Filling and Slope Shaping in Deep Water Breakwater of Large Self-Propelled Trailing Suction Dredger

以大型吹填工程斯里兰卡科伦坡港口城发展项目为背景,介绍了大型自航耙吸式挖泥船实施深水防波堤堤心砂抛填及理坡的施工过程及操作要领,开创了大型自航耙吸船在无遮蔽开敞海域单船独立完成深水防波堤堤心砂的抛填及理坡一次性成型的先例。论文对此施工工艺的前期准备、施工过程、质量控制及成果等过程进行了系统性的总结和探讨。

Based on the development project of Colombo Port City, Sri Lanka, which is a large-scale hydraulic fill project, this paper introduces the construction process and operation essentials of large-scale self-propelled trailing suction dredger for sand filling and slope regulation of deep-water breakwater core. It sets a precedent for large-scale self-propelled trailing suction dredger to independently complete sand filling and slope regulation of deep-water breakwater core in open sea area without shelter. This paper systematically summarizes and discusses the preparation, construction process, quality control and results of this construction technology.
