PIPELINE STRUCTURE AND COMPUTER READABLE RECORDING MEDIUM HAVING RECORDED THEREON PROGRAM FOR PIPELINE STRUCTURE

摘要

There are provided a pipeline structure and a computer readable recording medium having recorded thereon a program that supports the design of the pipeline structure. The pipeline structure includes two collars and a plurality of short pipes. The plurality of short pipes are connected by joint structures. Two collars are arranged to sandwich a zone where a fault displacement is expected to occur, and thereby, a ground displacement in the pipe axis direction is dealt with (absorbed). The plurality of short pipes are connected by the larger number of joints than the number of joints in the case of arranging a long pipe. By increasing the number of joints, it becomes easier to deal with (absorb) a ground displacement in the direction perpendicular to a pipe axis.

主权项

1. A pipeline structure of a buried pipeline, comprising:
at least two collars spaced apart from each other; and a plurality of pipes, said pipes being connected to one another by joints to provide the pipeline formed of said pipes, wherein an inter-collar pipeline is formed of said pipes and opposing ends thereof are connected to said collars spaced apart from each other, an extra-collar pipeline is formed of said pipes and only one end thereof is connected to said collar, and comparing said inter-collar pipeline and said extra-collar pipeline of the same length, the number of said joints is larger in said inter-collar pipeline than in said extra-collar pipeline.
