TRAVERSING DRAINAGE TOOL FOR AFFORESTATION STRIP ROAD
To provide a traversing drainage tool for an afforestation strip road which is formed so that a water beating part of drained flowing water comes at natural ground further on the lower side than banking.SOLUTION: A traversing drainage tool for an afforestation strip road which is provided on an unpaved afforestation strip road and which dams and discharges flowing water includes: a long support square bar; and a first elastic material and a second elastic material mounted on the support square bar. The first elastic material is formed in a belt-like manner and mounted on the support square bar with an upper end protruding from an upper surface of the support square bar. The second elastic material is formed in a belt-like manner and, out of both end parts, one end part is fixed on the upper surface of the support square bar, and the other end part is not fixed.SELECTED DRAWING: Figure 1
【課題】排出される流水の水叩き部が盛土より下方の地山になるように形成された造林用作業道横断排水具を提供することを目的とする。【解決手段】未舗装の造林用作業道に設けられ、流水を堰き止めて排出する造林用作業道横断排水具であって、長尺の支持角材と、該支持角材に取付けられた第１の弾性材及び第２の弾性材を備え、前記第１の弾性材は、帯状に形成され、上端が前記支持角材の上面より突出して前記支持角材に取付けられ、前記第２の弾性材は、帯状に形成され、両端部のうち、一方の端部は前記支持角材の上面に固定され、他方の端部は固定されていないことを特徴とする。【選択図】図１
