[Prior art]
Conventional revetment structures are constructed by stacking unit blocks vertically and horizontally and joining blocks adjacent vertically and horizontally closely to each other, so that gaps such as fry and aquatic insects can escape. There is no space. Also, because of the retaining wall, even in a block constructed on a mountain slope or the like, the wall surface is covered with a concrete block, and the environment is not an environment where vegetation of plants and creatures can live. For this reason, in recent years, in order to protect the natural environment, a revetment structure taking into account the ecosystem has been desired.
[0003]
As a revetment structure having a fish nest function, for example, Japanese Utility Model Application Publication No. Sho 54-65896 proposes a revetment structure in which a space for a fish nest is provided for enhancing the breeding of fish. For the construction of this revetment structure, a box-type block whose upper and lower surfaces are completely open is used, and this block is connected to the bottom of a waterway etc. in the left and right direction, and is stacked in multiple stages up and down according to the height of the shore The seawall structure is used as a space for fish nests, but this revetment structure is a structure in which the lowest block is placed on the foundation concrete, and it is formed flat, and fry and young fish etc. There is no escape space to avoid predation by foreign enemies such as adults. Such a structure in which the riverbed is covered with a concrete block is not an environment suitable for growing small animals such as microorganisms and aquatic insects living in the soil. Further, even in a block constructed on a slope of a mountain or the like, the wall surface serving as a vegetation soil layer is covered with a concrete block, so that the environment is not suitable for plant vegetation.
[0004]
Therefore, the present invention provides an environment suitable for the breeding and growth of small animals such as fish and aquatic insects, and the establishment and growth of plants such as aquatic plants, and is effective in improving the preservation of the ecosystem in the water, shore, and retaining wall. It is to provide ecological conservation type blocks.
