Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a greening slope and a method for forming the greening slope, which protects the slopes such as watersides of mountains and rivers and further performs greening.

[0002]

2. Description of the Related Art Conventional greening slopes have a grid-like frame made of cast-in-place concrete on the slope and vegetation surrounded by the frame, and a slope has a planter box. In some cases, the planter box was covered with a concrete block, and mulch was placed in the planter box for vegetation.

[0003]

In the above conventional greening slope, the former only protects the slope with a grid-like concrete frame, so the protection is weak, and the soil inside the frame is protected by heavy rain. There was a case where it leaked out and the slope was eroded and the frame rose from the slope. The latter has strong protection because the entire slope is protected by concrete blocks, but concrete blocks with planter box parts are complicated in shape and expensive, and are sometimes used as retaining walls on steep slopes. However, it is not suitable for loose slopes. The present invention solves these problems,
The present invention has been made in order to provide a green slope and a method for forming the green slope, which is inexpensive and has a strong protective power.

[0004]

According to the present invention, a porous sloped concrete block is laid side by side to form a porous concrete layer having a large number of holes, and a green slope and a large number of porous concrete blocks are laid out. Is a method for forming a green slope, which comprises a step of forming a porous concrete layer having holes, a step of filling the holes with soil such as mulch and a step of vegetation in the holes. Instead of the porous concrete block, it is also possible to use a block whose surface is ordinary concrete and whose back surface is porous concrete.

[0005]

[Function] Porous concrete is a porous concrete produced by remarkably increasing the coarse aggregate ratio as compared with normal concrete, and it has water permeability and water purifying property due to the growth of microorganisms in the pores. Are known.

In the present invention, since porous concrete blocks are laid out to form a porous concrete layer having a large number of holes, vegetation is applied to the holes so that the roots of the plants can form a large number of holes in the bolus concrete. When entering, the plant and concrete are integrated and the protection is strengthened, and sediment and plants are not washed away even when heavy rain falls. In addition, microorganisms inhabit a large number of pores of porous concrete and decompose organic matter to form fertilizers, so plants grow quickly. When it is constructed at the water's edge of rivers and lakes, it decomposes organic substances contained in the water, so it also has the ability to purify water. In addition, a few years after construction, mulch soil accumulates on the bolus concrete layer, and the small vegetation that grows on it can take root in the porous concrete layer, creating a natural landscape where no concrete is exposed.

When a block of which the surface is normal concrete and the back is porous concrete is used in place of the porous concrete block, the strength of the block itself increases, so that the block can be made thinner or used on a steeper slope. Although it has the advantage that rainwater does not easily penetrate into the lower layer and has a strong protection against heavy rain, it cannot be expected that plants will take root on the concrete layer.

If the connection between the blocks is made to be a flexible and loose connection, even if there is some unevenness on the slope, the joint layer can be deformed to form a concrete layer without unevenness, so that the construction work It ’s easy. Further, even if the earth and sand below the concrete layer is washed away by rain, the concrete layer deforms and conforms to the shape of the lower layer, and no space is created below the concrete layer.

If a plurality of blocks are connected in advance before laying them out, the assembly of the connected blocks can be laid by laying them with a crane so that work efficiency at the site is good.

The present invention will be described in more detail below with reference to the drawings relating to the embodiments of the present invention. FIG. 1 is a side view of a block 1 used in the present invention, and FIG. 2 is a block 1 on a slope.
FIG. 3 is a sectional view of the block 10 used in the present invention, and FIG. 4 is a block 2 used in the present invention.
It is a perspective view of 0.

The block 1 shown in FIG. 1 is made of porous concrete, the central portion 2 is formed in a cylindrical shape, and the end portions 3 on both sides are formed in a convex hemisphere shape. A chain 4 is embedded over the entire length in the longitudinal direction, and both ends are formed at both ends. The end of the chain 4 is exposed. When laying them out, the chains 4 with exposed block ends are connected in advance by shackles to connect a number of blocks, and at the site, the connected block aggregates are hung up by a crane and laid out. Since the connecting portions of the block 1 are connected by the shackle, the adjacent blocks are flexible and loosely connected so that they can be displaced with respect to each other.

As shown in FIG. 2, when the blocks 1 are laid on the slope, holes 5 are formed in the connecting portions of the blocks. Since the hole 5 becomes a vegetation space, the hole 5 is filled with soil such as mulch and vegetation is applied. Even when the connecting portions of the blocks 1 are arranged in a staggered manner, holes having different shapes from those in FIG. 2 are formed.

The block 10 shown in FIG. 3 is made of porous concrete, but a plurality of blocks 10 are already connected by a chain 11 at the manufacturing stage. Usage is block 1 above
Is the same as.

The block 20 shown in FIG. 4 has a front surface 21 made of normal concrete and a back surface 22 made of porous concrete. Even if the blocks having such a shape are lined up, a porous concrete layer having a large number of holes can be formed.

The shape of the block in which a large number of holes are formed when laid side by side is not limited to the embodiment, and various shapes are conceivable. In addition, it is possible to lay out indeterminate blocks of different shapes one by one like natural stone.

[0016]

According to the present invention, since a porous concrete layer having a large number of holes is formed, vegetation is applied to the holes so that the roots of the plants enter a large number of holes of the bolus concrete, and the plants and the concrete. The integrated protection will be strengthened, and sediment and plants will not be washed away even if heavy rain falls. In addition, since organic substances are decomposed into fertilizer by the action of microorganisms that live in many pores of porous concrete, plant growth is fast, and it contributes to water quality purification when applied at the water's edge of rivers and lakes. Since it is not necessary to provide the planter box portion on the block body, the block body can have a simple shape and can be manufactured at low cost.
