Description

この考案は、盛り土をして構築した道路のように、その両側又は一側の路肩から下る方向に傾斜した法面を有する道路の当該路肩の崩落の防止及び当該法面に雑草が生えるのを防止(防草)する構造に関するものである。   This device prevents the fall of the road shoulder of a road having a slope inclined downward from the shoulder on either side or one side, such as a road constructed by embankment, and prevents weeds from growing on the slope. It relates to a structure to prevent (weedproof).

盛り土をして構築した道路の路肩に続く土の法面は、そのままにしておくと雑草が生い茂り、草刈のために多大な労力と経費が必要になる。また、土の法面の頂部に位置する路肩は、降雨により土が流れてアスファルトの表層が庇状になって崩落する危険もあり、これに対する維持管理上の注意も必要である。そこで路肩の保護を兼ねた法面の防草構造として、路肩にコンクリート二次製品からなる路肩ブロックを敷き並べ、法面には板状の法張りブロックを敷き並べて路肩の保護と共に法面の保護及び防草を行う保護構造が公知である。   If the soil slope that follows the shoulder of the road constructed by embankment is left as it is, weeds will grow, and a great deal of labor and expense will be required for mowing. Moreover, the road shoulder located on the top of the slope of the soil has a risk that the soil flows due to rain and the surface layer of the asphalt becomes a saddle and collapses. Therefore, as a slope weed protection structure that also protects the road shoulder, a road shoulder block made of concrete secondary product is laid on the road shoulder, and a plate-like legged block is laid on the slope to protect the road shoulder and protection of the slope. And the protection structure which performs grass prevention is known.

法張りブロックで法面の防草を行う構造は、ブロックが重たいために付設にパワーショベルやクレーンなどの重機を必要とし、コスト高になる。そこで再生プラスチックでできた防草板や不織布でできた防草シートを法面に被せて防草を行う構造が提案されている。   The structure that protects the slope with a lawn block requires heavy equipment such as a power shovel and a crane because the block is heavy, and the cost is high. In view of this, a structure has been proposed in which grass protection is made by covering a slope with a grass protection plate made of recycled plastic or a grass protection sheet made of nonwoven fabric.

例えば下記特許文献1には、再生プラスチックで道路路肩段面に整合して形成した路肩保護兼雑草防止装置が提案されており、特許文献2には、間伐材などの複数の木材を並列に索条又は線材で連結した構造の路肩の防草構造が示されている。また、特許文献3には、路肩ブロックの成型時にポリプロピレン製の織布の上辺を当該ブロックと一体化して成型し、当該織布で法面を覆う構造が提案されている。
