Description
図5や図6に示す構造物(特許文献1,2,3参照)は、沖合からの波を消波することによって構造物の背後を静穏域にする。そして、海岸線に対して平行に動いている沿岸漂砂をこの構造物の背後に堆積させることで、海岸侵食を抑制しようとする方法である。ところが、河川などから海岸への土砂供給量が少ない場合、このような構造物を設置すると、沿岸漂砂の上手側(土砂供給源に近い側)の構造物の背後には砂が堆積するが、それより下手側への漂砂量が減少するため、下手側の構造物の背後には砂が堆積せず侵食が続くという問題がある。また、新しく構造物を建設することになるため、侵食対策コストが高くなるといった問題もある。
[1]海底における砂の移動限界水深域の海底に、粒径が1.5mm以上である水砕スラグ及び製鋼スラグの混合物による堆砂域を設ける養浜工法であって、さらに前記製鋼スラグは2mm以上の粒径のものが質量百分率で50%以上であることを特徴とする養浜工法。
[2]前記混合物に、さらに砂を混合したものを用いることを特徴とする[1]に記載の養浜工法。
