れている。 As described above, the left and right earth retention blocks 1 and 1 are integrated, but the left earth retention block 1 is further integrated with the earth retention block 1 adjacent to the left, and the right earth retention block 1 is further integrated with the earth retention block 1 adjacent to the right. , a plurality of retaining blocks 1 that are continuous from side to side are connected in a chain.
左右の土留ブロツク1,1の翼部3,3によつ
て地山7側へ窪むアーチ部Aが形成される。この
アーチ部Aを利用して棚部Bを形成する。 The wing parts 3 and 3 of the left and right retaining blocks 1 and 1 form an arch part A that is recessed toward the ground 7 side. This arch section A is used to form a shelf section B.
すなわち土留ブロツク1は上下にも積み重ねる
が、この上下の土留ブロツク1,1間に棚ブロツ
ク10を挾んで植生棚Bを形成するものである。 That is, the retaining blocks 1 are stacked vertically, and the shelf block 10 is sandwiched between the upper and lower retaining blocks 1 to form a vegetation shelf B.
棚ブロツク10は直角を成す底板11と側板1
2によつて断面L字状に形成されている。この棚
