PILLAR, UPPER-STAGE HORIZONTAL ROPE AND HANGING ROPE IN POCKET TYPE ROCKFALL PROTECTION NET
To provide a pocket type rockfall protection net provided as a rockfall protection facility, in which a pillar that secures an opening is likely to be damaged by direct impact of rockfall; in such a site, it is necessary to consider the installation position and arrangement interval of the pillars as a measure to avoid the direct impact of rockfall.SOLUTION: With respect to a conventional type pocket type rockfall protection net comprising a plurality of pillars, a pillar suspension rope for supporting the standing state of the pillars, an upper-stage horizontal rope laid between the pillars and forming an opening with respect to a slope, and a net portion, a pocket type rockfall protection net is provided which is further provided with a horizontal rope hanging rope that is connected so as to hang the upper-stage horizontal rope.SELECTED DRAWING: Figure 1
【課題】落石防護施設として整備されるポケット式落石防護網について、開口部を確保する支柱は、落石の直撃を受けて破損する可能性は高い。そのような現場においては、落石の直撃を避けるための措置として、支柱の設置位置や配置間隔を検討する必要がある。【解決手段】複数の支柱と、該支柱の立設状態を支持する支柱吊りロープと、支柱間に架設され斜面と間に開口部を形成する上段横ロープと、網部と、を備えた従来型のポケット式落石防護網に対して、上段横ロープを吊持するよう連結された横ロープ吊りロープを更に備えたポケット式落石防護網。【選択図】図１
