<p>PURPOSE:To reduce the stress by thermal expansion constraint by providing a pipeline support member, a pipeline positioning seat, a support frame for supporting the pipeline support member, and a box formed of a steel plate around the support frame, and charging a fine particle in the box. CONSTITUTION:A support frame 1 is formed into a box by a steel plate 9 and a mold 11, and a fine particle 8 is charged therein. A pipeline 3 buried in the fine particle 8 is constrained by the fine particle 8 at the time of an earthquake. The pipeline 3 is supported by a pipeline support member 2, which is fixed to the support frame 1. The support frame 1 is fixed to a construction 6 such as building through a support frame support member 5. Consequently, the movement of the pipeline in pipe axial direction is facilitated, and the factor of stress generation by thermal expansion constraint of the pipeline can be removed.</p> |
