DESIGN METHOD AND MANUFACTURING METHOD FOR OUTFLOW PREVENTION FENCE
To provide a design method and a manufacturing method for an outflow prevention fence which can reduce a manufacturing cost, and suppress the scale of installation work while improving absorption capacity of collision energy.SOLUTION: A design method for an outflow prevention fence 1 includes: a collision energy acquisition step of acquiring a value of collision energy when a drift 102 collides with an outflow prevention fence 1; and a support material selection step of selecting, as a support material, a steel pipe capable of completely absorbing collision energy corresponding to a value acquired in the collision energy acquisition step in both a first collision energy absorption form of bending and deforming a first collided support 24 by collision of the drift 102 with the first collided support 24, bending and deforming two adjacent supports 25 by drawing, and thereby absorbing collision energy, and a second collision energy absorption form of bending and deforming two second collided supports 26 by collision of the drift 102 with two adjacent second collided supports 26, and thereby absorbing collision energy.SELECTED DRAWING: Figure 7
【課題】衝突エネルギの吸収能力を向上しつつ、製造コストの削減及び設置工事の規模の抑制が可能な流出防止柵の設計方法及び製造方法を提供する。【解決手段】流出防止柵１の設計方法は、漂流物１０２が流出防止柵１に衝突するときの衝突エネルギの値を取得する衝突エネルギ取得過程と、第１被衝突支柱２４に漂流物１０２が衝突して第１被衝突支柱２４が曲げ変形するとともに２本の隣支柱２５が引きつられて曲げ変形することにより衝突エネルギを吸収する第１の衝突エネルギ吸収形態と、互いに隣り合う２本の第２被衝突支柱２６に漂流物１０２が衝突して２本の第２被衝突支柱２６が共に曲げ変形することにより衝突エネルギを吸収する第２の衝突エネルギ吸収形態とのいずれにおいても衝突エネルギ取得過程で取得された値に相当する衝突エネルギを吸収しきることが可能となる鋼管を支柱材として選定する支柱材選定過程と、を備える。【選択図】図７
