PROTECTIVE STRUCTURE AND CONSTRUCTION METHOD THEREOF
To provide a protective structure that offers excellent fitting strength for a support pillar fitted on an installation surface.SOLUTION: With a protective structure 1 having a plurality of support pillars 3, 3 erected on a slope S leaving an interval in right and left directions and a protective fence 2 with a protective surface 4 provided between the support pillars 3, 3, an anchor rod 11 is buried and fixed on the slope S and the support pillar 3 is externally fitted on the anchor rod 11, at the same time burying and fixing a lower portion of the support pillar 3 on the slope S. The configuration causes a top portion of the anchor rod 11 to be exposed to flexural stress when collapsed sediment, etc. exerts toppling force on the support pillar 3, but the support pillar 3 fitted externally on the top portion of the anchor rod 11 enhances the flexural capacity of the anchor rod 11.SELECTED DRAWING: Figure 2
【課題】設置面に対する支柱の取付強度に優れた防護構造を提供する。【解決手段】左右方向に間隔を置いて斜面Ｓに複数の支柱３，３を立設し、これら支柱３，３の間に防護面４を設けた防護柵２を備えた防護構造１において、斜面Ｓにアンカーロッド１１を埋設固定し、このアンカーロッド１１に支柱３を外装すると共に、該支柱３の下部を斜面Ｓに埋設固定する。これにより崩壊土砂などにより支柱３を倒す力が加わると、アンカーロッド１１の上部に曲げ応力が加わるが、アンカーロッド１１の上部に支柱３を外装することにより、アンカーロッド１１の曲げ耐力を向上することができる。【選択図】図２
