<p>PURPOSE:To prevent floating of a buried pipe and simplify the burying work by fastening the two ends of a cable set on the pipe periphery with anchor bolts implanted at a certain spacing along the pipeline, putting in a fluidification soil for backfill, and burying the pipe. CONSTITUTION:When construction of a pipe bedding 2 is made at the bottom of an excavation groove 1 furnished along the pipeline embedded, anchor bolts 3, 3 are implanted at a certain spacing along the pipeline and the part is left to harden as it is. Then a pipe 4 is laid on this pipe bedding 2. and a cable 5 is set on the pipe periphery, and the two ends of the cable are fastened with the anchor bolts 3, 3. Then a fluidification soil 6 for backfill is put in, and the pipe is buried. Thereby the pipe is certainly prevented from vertical motions by the anchor bolts to permit safe putting-in of the fluidification soil, so that the pipe backfill work can be conducted very easily. Further, this does not at all require any beam or the like for holding the pipe, so that the works can be executed quickly to achieve shortening of the construction period.</p> |
