- 摘要:
- 随着国内海底管道建设的不断增多，管道铺设技术也在不断提升。传统海底管道铺设多为单条管道全部带混凝土配重或全部不带混凝土配重两种形式。在连江可门海底管道项目的最初设计中，整体路由全程采用80 mm厚的混凝土配重层，经过深入的技术经济分析，创新性提出分段配重优化方案，根据项目海况、水深、管道参数等因素，从管道受力和铺管稳定性方面进行分析，将整个管道施工分为K0-K6段和K6-K13段，前段管道采用不带混凝土配重层设计，后段管道则维持80 mm厚的配重层。这一优化方案不仅保证了工程质量及安全要求，还降低了项目施工成本，可为国内海洋管道施工技术持续提升提供参考和借鉴。
With the increasing number of domestic submarine pipeline constructions, pipeline laying technology is also constantly improving. In traditional submarine pipeline laying, there are mostly two types of pipeline, including a pipeline entirely with a concrete counterweight or a pipeline entirely without a concrete counterweight. In the initial design of the Lianjiang Kemen submarine pipeline project, an 80 mm-thickness concrete counterweight layer was adopted for the entire route. After in-depth technical and economic analyses, the project team innovatively proposed a segmented counterweight optimization scheme. According to such factors as the project's sea conditions, water depth, and pipeline parameters, the entire pipeline construction was divided into the K0-K6 section and the K6-K13 section based on the analysis of pipeline stress and pipeline laying stability. The former section of the pipeline adopted a design without a concrete counterweight layer, while the latter section maintained an 80 mm-thick counterweight layer. This optimization scheme not only ensures the project quality and safety requirements, but also reduces the project construction cost, providing references for sustainable improvement of domestic offshore pipeline construction technology.
