The Behavior of Buried Flexible Pipe in Peat Ground
説明
The very weak peat soil stretches over Sorachi District in Hokkaido which is an extremely important agricultural area. There are many agricultural facilities that encounter geotechnical problem, such as long-term settlement. The settlement of the bedding of pipeline has been a serious problem. In this study, two types of field tests were conducted using the Fiber-reinforced plastic mortar pipe and polyvinyl chloride pipe having diameters 700mm and 350mm, respectively. By changing the bedding materials using sand and peat, comparison experiments were carried out on the deflection of pipe and circumferential strains, and pipe settlements. Contrary to existing design specifications that require sand as bedding material, the test result showed that the deflection of pipe using the peat as bedding material was smaller than that of sand.
