长距离大口径尾水排海管道施工关键技术

Key technologies in the construction of long-distance,large-diameter sea outfall pipelines

对于长度在3km以上的长距离尾水排海管道,一般采用铺管船法施工,以莆田东吴浆纸基地尾水排海工程为例,介绍了长距离大口径尾水排海管道海域段、登陆段、扩散段施工的关键技术,对于类似工程的施工具有参考意义。

For long-distance tailwater discharge pipelines exceeding 3 kilometers in length,pipeline laying vessel method is generally employed for construction.Taking the tailwater discharge project at the Putian Dongwu Pulp Paper Base as an example,this paper introduces the key technologies for constructing marine segments,landfall segments,and diffusion segments of long-distance,large-diameter tailwater discharge pipelines.The insights and methodologies discussed here can be referenced for similar projects.
