DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seawall, a seawall, an aquatic insect, a crustacean and the like, which protects a slope of a river or the like, and which can grow a plant. is there.

[0002]

2. Description of the Related Art Various concrete blocks are used for embankment of slopes on rivers and the like, and the entire slope is covered with concrete and the surface of the concrete is gray. Has been exposed, destroying the natural ecosystem and degrading the natural environment and landscape.
Therefore, recently, greening is performed by putting soil in a square frame, natural cobblestone, iron flat stone, etc. are buried in the concrete surface, and relatively small through holes are formed to vegetate flowers and the like. The revetment using the law lining block is performed.

[0003] The material to be occupied in the legal framework has a large opening of about 1 m in the legal framework, and the thickness of the clay is 15 cm.
Because the front and rear sides are thin, the sediment in the slope is easy to flow out due to rainwater and the like, and there is a danger that the greenery and the soil on the slope will be scooped out due to the outflow. Embedding natural cobblestones and iron slabs in concrete, on the other hand, is useful for protecting slopes and restoring the landscape, but it is far from the natural scenery full of greenery. Pre-treatment to prevent the laying of concrete and concrete from coming out of the surface of natural stone takes time, the number of manufacturing steps is increased, and obtaining natural stone itself is difficult and expensive. Is in a situation where you cannot get it. Also,
Even if a through hole is formed, only a part of the hole can be greened, and the hole will inhabit as much as an insect, but it is impossible to restore the natural landscape and natural ecosystem.

There is a demand for a law lining block that matches the scenery in addition to the function of preventing the slope from being washed down. In recent years, it has been said that the natural beauty of vegetation and the like together with natural stones is most in harmony with the surrounding environment, and a method lining block having a vegetation function and a fish nest function has been demanded. However, in the case of natural stone or pseudo stone pattern on the surface of the concrete, or in the case of simply forming a small through hole, the surface and the back soil are cut off by the concrete, and the vegetation and seafood are cut off. There was a problem that the species could not inhabit.

[0005]

As described above, the function of protecting the slope from scouring and collapsing and the growth of plants in the high water area of the slope of the river, as well as the fish and aquatic water in the low water area of the slope. It is intended to provide a more economical supply of slope protection blocks that have the function of inhabiting insects and crustaceans and that match the natural environment.

[Means for Solving the Problems]

(5) The vegetation and fish nest function according to the above (1) to (4), wherein the rectangular substrate is formed so as to protrude slightly from a concave portion surrounded by four peripheral walls to be wide. A seawall with a seawall.

[Action]

The lining block is placed on the slope of the river at the high water level on the river bank, and the soil with seeds is buried inside the concave portion, and almost the entire surface of the block is grown by growing plants and the like. It can create a natural atmosphere by being covered with plants. In addition, by installing the lining block on the slope of the low water level and placing gravel, chestnut stone, cobblestone, etc. inside the concave part, fish and shellfish, aquatic insects, crustaceans live in the gaps In the meantime, soil enters the gap near the bottom of the river on the slope, and the aquatic plants thrive and form a feeding ground, an egg laying place, and a nest, forming a natural waterside space.

[0013] By arranging the lining blocks on the slope of the river bank so that the wall side where the drain holes are formed is located below, the rainwater due to rainfall does not stay in the concave portion and the outside of the block. Drains quickly and flows down the bottom of the slope through the grooves formed on the outer periphery of the wall, preventing root rot of the plants in the block and scouring and collapsing by rainwater penetration into the slope To prevent

Since the rectangular substrate is made of porous concrete, there is a gap between the aggregates. Therefore, when the substrate is used as a revetment for low water level, it is separated from the soil covered with the concrete by concrete. Air and water are circulated between the sloped soil and the soil is activated, creating a favorable condition for plant growth, and a comfortable environment for insects and larvae growing in the soil. I will provide a.

The lining block is placed in the water on the slope of the waterside, and soil, sand, gravel, chestnut stone, cobblestone, and the like are interposed between the concave portions so that aquatic plants, moss, and the like prosper, and gaps are formed. It inhabits seafood, aquatic insects, and crustacean organisms, forms a feeding ground for aquatic organisms, spawning grounds, and nests, forms a natural waterside space, and provides a feeding ground for water birds.

By embedding or fixing woods such as pine and cedar, embedding natural stones such as iron flat stone and cobblestone, and forming artificial wood or artificial stone patterns on the upper surface of the wall at the outer peripheral edge of the rectangular substrate, plants can be planted. Trees, stones and patterns appear parallel to the belt surface on the soil surface until they grow, and by combining them, a more natural look is achieved. In particular, when the flower grows, it seems that the use of wood such as pine and cedar rather than stone makes it more natural and soft.

[0017] Both walls adjacent to the wall in which the drain hole is formed are formed low, and the entire surface of the method lining block is subjected to a net-like or lattice-like sheet of glass fiber or synthetic resin and a rustproof treatment. By fixing the net made of the applied metal on the upper surface of the lower wall, the net can be hidden shallowly in the soil, and the roots of the plants are entangled with each other, so that the sediment is prevented from being washed away by the increase of heavy rain. When gravel, chestnut stone, cobblestone, etc. are installed in the concave portion of the lining block, excavation due to a rapid portion having a high flow velocity or turbulence during heavy rain is prevented, and a good habitat can be maintained for many years.

[0018] After the method lining block is constructed, it is time-consuming and requires skill to put soil containing seeds in the inside of the concave portion, or to install gravel, chestnut stone, cobblestone and the like inside the concave portion. Therefore, before the installation, the seed mixed soil, gravel, chestnut stone, cobblestone, etc. were installed at the manufacturing plant or construction site,
It can be prevented by spilling by holding it down with a net or a net and simply installing it, which can contribute to labor saving and labor saving required in recent years.

The U-shaped water supply is formed between the concave portions by laying the rectangular lining blocks, each of which has a rectangular substrate protruding slightly wider than the concave portion, on the slope, and water overflowing from the concave portion during heavy rain. Is collected in a U-shaped waterway and quickly drained downward, so that floodwater or the like in which water upstream of the slope gathers downstream does not scour the soil.
