Abstract:Taking the Xuwei New District Up-to-standard Tail Water Sea-discharging Project as an example, the laying construction of the discharge pipe in the deep-sea section is required to strictly control the bending curvature of the pipeline within the allowable range in order to ensure the safety of the pipeline, and the construction is very difficult. By introducing a deep-sea pipeline laying construction method suitable for the deep water conditions, the construction technological parameters are quantitatively calculated and analyzed, which can provide the reference for the similar projects.
