Description of the Related Art The foundation of a conventional pipeline (closed channel for pipes and culverts) is intended to prevent the pipeline from descending and displacing for many years with respect to its supporting ground, and therefore, the strength of the pipeline supporting ground is insufficient. In such a case, various methods such as sand replacement at the lower part of the pipeline laying, ground improvement, pile support, pipeline foundation installation, and ladder trunk installation are used.

た。The above-mentioned method of maintaining each area is still not perfect, and there are various problems.
In other words, in the event of an earthquake or crustal deformation, the pipeline changes over time in three-dimensional directions, and not only in a simple axial displacement of the pipeline, but also in a repetitive and repetitive manner. (Relative displacement with the soil).

し、管路事故を生じ易い問題点があった。[0005] The pile support and the concrete foundation employ a rigid support method to cope with the displacement. However, constructing the concrete foundation requires not only enormous costs and materials but also pipes. When the road is laid on the water floor, there is a problem that the construction becomes difficult. In addition, there is a problem that the flexible joint is broken without being able to adapt to a large displacement of the ground, and a pipe accident is likely to occur.

られている。2. Description of the Related Art The foundation of a conventional pipeline (closed channel for pipes and culverts) is intended to prevent the pipeline from descending and displacing for many years with respect to its supporting ground, and therefore, the strength of the pipeline supporting ground is insufficient. In such a case, various methods such as sand replacement at the lower part of the pipeline laying, ground improvement, pile support, pipeline foundation installation, and ladder trunk installation are used.

た。The above-mentioned method of maintaining each area is still not perfect, and there are various problems.
In other words, in the event of an earthquake or crustal deformation, the pipeline changes over time in three-dimensional directions, and not only in a simple axial displacement of the pipeline, but also in a repetitive and repetitive manner. (Relative displacement with the soil).

し、管路事故を生じ易い問題点があった。[0005] The pile support and the concrete foundation employ a rigid support method to cope with the displacement. However, constructing the concrete foundation requires not only enormous costs and materials but also pipes. When the road is laid on the water floor, there is a problem that the construction becomes difficult. In addition, there is a problem that the flexible joint is broken without being able to adapt to a large displacement of the ground, and a pipe accident is likely to occur.
