长乐外海海上风电场工程中的吸力式导管架基础沉贯施工工艺

Construction Technology of Suction Jacket Foundation Penetration in Changle Offshore Wind Farm Project

吸力式导管架是海洋工程设备应用领域的一项新型技术,具有费用低、用时短、无噪声、可重复利用等多项优点,被广泛应用于我国沿海地区的海上风电基础施工项目中。由于非陆地施工的特殊情况,海上施工受周边环境不稳定因素制约,对所用导管架结构的刚度及重量要求也较高,故在施工过程中存在一定的操作难度。为此,文章以长乐外海海上风电场工程为例,围绕吸力式导管架的基础沉贯施工展开详细分析,以供参考。

The suction jacket is a new technology in the application field of marine engineering equipment. It has many advantages such as low cost, short time, no noise, and reusability. It is widely used in offshore wind power infrastructure construction projects in coastal areas of China. Due to the special situation of non-land construction, the offshore construction is restricted by the instability of the surrounding environment, and the requirement for the stiffness and weight of the jacket structure is also high. Therefore, there is a certain difficulty in operation in the construction process.For this reason, taking Changle offshore wind farm project as an example, this paper analyzes the foundation penetration construction of suction jacket in detail for reference.
