DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the protection of civil engineering and architectural structures, for example, the outer surfaces of buildings, indoor walls, roofs, rooftops, vertical surfaces such as block walls, slopes such as retaining walls, and highway protection. The present invention relates to a water purification block for vegetation, a base material for water purification for vegetation, and a greening method for civil engineering and architectural structures using the water purification block for vegetation, which is used for greening walls, seawalls and the like. Further, the present invention relates to a vegetation water purification block, a vegetation water purification base material, and a water purification method for rivers and the like used for maintaining, purifying, or adjusting water quality of rivers and lakes, or for growing aquatic animals and plants.

[0002]

2. Description of the Related Art Conventionally, the outer surface of a civil engineering structure, for example,
Retaining walls are created on the slopes created by the development of residential land and the opening of roads, etc. by placing concrete or constructing concrete blocks, thereby preventing the collapse.
In response to the recent trend of beautification of the surrounding environment, the following general methods are available for greening such slopes. That is, an artificial soil such as peat moss and bark compost was laid on a concrete retaining wall and an artificial soil such as peat moss and bark compost was sprayed and seeds were sprayed for greening. This is a method of greening by constructing a retaining wall using concrete blocks and growing plants through the vegetation holes.

In the conventional flood control works for rivers and ponds, a general measure is to simply lay a concrete block to construct a revetment and prevent flood damage.

[0004]

However, in the above-mentioned base material spraying method, a large amount of base material to be sprayed cannot be sprayed because the base material to be sprayed flows down from the retaining wall due to its own weight or wind and rain, that is, a soil layer necessary for vegetation is not formed. Cannot be formed. Therefore, even if the seeds germinate, the seeds wither due to a lack of water or an increase in the temperature of the ground, so that there is a problem that the purpose of greening the slope is hardly achieved.

In the method of using a concrete block in which artificial soil is provided in advance in a vegetation hole as a retaining wall to achieve greening, concrete has almost no function of absorbing and draining water. If not, it will die due to lack of water, while if it keeps raining, excess water will continue for a long time, and root rot is likely to occur. Furthermore, because of prolonged rain, the vegetation hole becomes a drainage channel for rainwater like a drainage pipe provided on a concrete retaining wall, and artificial soil is washed away, so that the target area cannot be greened after all. There was a point. In addition, concrete has little air permeability, so it is difficult for bacteria and the like to multiply, and even if it temporarily takes root, it dies due to lack of nutrients and so it is difficult to plant trees for a long time. Was.

In the conventional flood control works for rivers and ponds, concrete blocks are laid to construct a revetment, so that it is difficult to secure a dwelling place for aquatic animals and plants, and as a result, they are difficult to grow. There was a problem that it contributed to the deterioration of water quality.

That is, since these places are artificially created, it is difficult for animals and plants to grow spontaneously.
On the other hand, if an environment where animals and plants are easy to grow is created, in the case of above-ground structures, greening them by planting or the like leads to environmental beautification, energy saving, and the like. In addition, in the case of underwater structures, it is clear that the growth of aquatic animals and plants can be promoted, and the maintenance, purification, and adjustment of water quality can be achieved.

The present invention has been made in view of the above-mentioned conventional problems, and facilitates maintenance after construction when growing plants and the like in civil engineering and building structures and the like, which are conventionally considered to be difficult to green. The purpose of the present invention is to achieve environmental beautification, water purification and the like by reliably growing plants and the like.
