登陆海底管道近岸段预挖沟

Near -Shore Preditching for the Landing of Submarine Pipeline

海底管道大都是由深水到浅水,经过潮差段登上陆地的。为确保海底管道在登陆段的稳定和生产期间的安全,一般都是采用预挖沟埋设的方法。本文根据近年来管道施工的经验,对管道登陆段的预挖沟方法、测量定位以及挖沟质量控制等做了详细地介绍。

Submarine pipelines land generally from deep water to shallow water, through tidal zone. Preditching method was applied in order to assure the stability of submarine pipeline on landing zone and its safety during production period. Preditching method.measurement and location and ditching quality control are described in detail based on the experience in submarine pipeline installation in recent years.
