抄録

Buried pipelines that have sagged can result in damage to welded joints, disconnections and so on. Performance can also be affected with stagnation or stoppage of flow, which can lead to major secondary problems, such as caved-in roads or effluent leakage. To overcome these problems, various methods have been proposed and used for the restoration of flow performance and fixing damaged sections of underground pipelines without the need for excavation. However, there are not many methods available that do not require excavation for repairing reduced flow performance and stoppages, or pipeline damage caused by sagging, which is thought to be the major contributor to this type of damage. The authors provide a report on construction methods and examples that do not require excavation, but instead use a system of grouting for the ground, surrounding the buried pipeline, to aid in the repair of the pipeline position, which can actually improve the surrounding foundations.
