ACTIVE FAULT COUNTERMEASURE PIPING, DESIGN METHOD FOR ACTIVE FAULT COUNTERMEASURE PIPING AND PROCESS OF MANUFACTURE OF ACTIVE FAULT COUNTERMEASURE PIPING
PROBLEM TO BE SOLVED: To provide a design method for an active fault countermeasure piping in which the active fault countermeasure piping for restricting leakage of stored item from a piping with a siphon at the time of earth crust motion can be efficiently designed.SOLUTION: A design method for an active fault countermeasure piping is a design method for the active fault countermeasure piping in which stored item in the piping is not leaked out of the piping when the active fault is moved at the time of earth crust motion at the piping 10 buried in soil 200 having an active fault 205 and provided with a siphon 20, the siphon includes a first straight pipe 26 extending along a first adjoining portion 11 adjacent to the siphon at the piping, a size Lof the siphon that is a distance between a central axis line of the first adjoining portion and a central axis line of the first straight pipe is determined to be adjusted on the basis of a position of the siphon along an extending direction D of the pipe in respect to a reference point Pthat is a crossing point between an active fault surface 208 of the active fault and a central axis line Cof the pipe or it is determined to arrange the active fault countermeasure part 30 constituted by a partial curved part of the pipe at the pipe.SELECTED DRAWING: Figure 11
【課題】伏越しが設けられた配管から地殻運動時に収容物が漏えいするのを抑える活断層対策配管を効率的に設計することができる活断層対策配管の設計方法を提供する。【解決手段】活断層対策配管の設計方法は、活断層２０５を有する地盤２００中に埋設され伏越し２０が設けられる配管１０において、活断層が地殻運動時に移動したときに配管内の収容物が配管から漏えいしない活断層対策配管の設計方法であって、伏越しは、配管において伏越しに隣接する第一隣接部分１１に沿って延びる第一直管２６を備え、活断層の断層面２０８と配管の中心軸線Ｃ０との交点である基準点Ｐ３に対する、配管の延在方向Ｄに沿った伏越しの位置に基づいて、第一隣接部分の中心軸線と伏越しの第一直管の中心軸線との距離である伏越しの大きさＬ２を調節することを決めるか、配管の一部が曲がっていることで構成された断層対策部３０を配管に設けることを決める。【選択図】図１１
