[Technology to which the Invention belongs]
TECHNICAL FIELD The present invention relates to a vegetation slope block used for protection and greening of a gentle slope formed with soil or covered with concrete.
[0002]
[Prior art]
Conventionally known methods for revegetating a gentle slope include a revegetation method of directly spraying soil containing seeds on the slope, a revegetation method of installing a vegetation sandbag in a frame frame laid on the slope. There is a construction method in which soil is covered on a porous concrete block laid on the surface and vegetation is vegetated on this soil layer, and a method in which porous concrete is installed on the vegetated slope to gradually grow and green.
[0003]
However, in the method of directly spraying the soil containing seeds, there is a problem of dripping or peeling of the sprayed soil, so that the formed vegetation base is thin and unsuitable for greening by large plants.
With the method of installing vegetation sandbags in the sill frame, a vegetation base equivalent to the thickness of the stake frame can be formed, but since the vegetation sandbags are directly exposed, when the sandbags are torn, rainwater The soil in the sandbags may be eroded or washed out, and it is not easy to secure a stable vegetation base for a long time.
In the method of vegetation by simply covering soil on the porous concrete block, the vegetation base formed by the soil cover is easily eroded by rainwater or easily flows out, so plant growth stops before the roots enter the porous concrete. In some cases, the plants themselves fell off and washed away.
The method of covering vegetated slopes with porous concrete solves the problem of erosion and runoff due to rain on soil and vegetation on the slopes, but it takes a long time to complete a green area with sufficient area and thickness. And
[0004]
[Problems to be solved by the invention]
Therefore, an object of the present invention is to form a vegetation base having a necessary and sufficient depth, protect the vegetation base from erosion and runoff by rainwater, and protect vegetation slopes and greenery at an early stage accurately and accurately. Is to provide a block.
