[0002]
[Prior art]
Conventionally, rectangular steel wire fences or box-shaped concrete blocks filled with filling stones are used by appropriately stacking them on riverbanks, retaining walls on slopes of roads and parks, and the like.
[0003]
However, in the case of a rectangular parallelepiped iron wire rod filled with filling stones, soil is sucked into the gaps of the stones even if the top cover of filling stones is covered with greening, or it is eroded by rainwater or running water. However, the function as a vegetation base deteriorates, and there is a disadvantage that the iron wire fence is well conspicuous and the scenery is damaged unless greening is achieved.
[0004]
In addition, even in the case of a box-shaped concrete block filled with filling stones, if the block has only a frame without a bottom plate, the greening cover applied to the top of the filling stones is eroded by rainwater or running water, and greening cannot be achieved. In the case of a concrete block with a bottom plate, drainage of the cover for greening can be avoided, but the movement of small animals and fish cannot be carried out by the concrete block, and the habitat and growth environment of organisms are significantly hindered. ,Getting worse.
