Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a concrete block for vegetation that can be greened with turfgrass and flowers.

"Conventional Technology" In the conventional concrete block for earth retaining, the surface of the concrete is exposed as it is, the skin surface is weathered for a long time, impairing the aesthetic appearance, and each surface is a flat shape,
There are few examples because it is difficult to attach to the slope and it is difficult to vegetate the block itself.

The conventional soil retaining concrete block is forced to have a dull and unsightly appearance due to the exposed surface and rough skin due to weathering, and it does not fit in with the natural aesthetic environment.
The slippery shape on the sloping surface has problems such as the first step, the second step, and the like as the number of steps increases, which causes the soil to slide off due to pressure.Also, even if you try to green the block itself because the upper slope is easy to dry, Vegetation After sprouting, plants had a difficulty in growing.

As a means for solving such a problem, for example, Shoukaikai 6
There was a thing as shown in the 2-129448 gazette. In this conventional technique, a through hole is provided in the central portion of the front end surface and the back end surface of the concrete block body, and a PVC net tube is inserted into the through hole to form a curing tool inside the PVC net tube. The interior is made of wood and the slope is planted with greenery.

"Problems to be solved by the invention" In the conventional concrete block body, as described above, a through hole is provided in the central portion of the front end surface and the back end surface of the concrete book body, and the PVC net cylinder is provided in this through hole. The protector material is inserted into the interior of the PVC netting and the protector material is placed inside.
As a result, when a plurality of concrete block bodies are piled up on the slope, the ratio of the exposed area to the concrete block is high compared to the ratio of the area to be constructed. There was a problem that early vegetation revegetation in the entire construction area could not be measured due to scattered vegetation revegetation.

"Means for Solving Problems" The present invention takes the following means in order to solve the above problems.

A central concave portion is provided in the center of the surface of a rectangular block having a curved tail portion, a through hole is bored in the central portion to insert a mesh pipe, and a base made of block-shaped granular soil in the central concave portion. In a concrete block for vegetation in which soil vegetation has been inserted, four peripheral recesses are provided leaving protrusions at four corners of the surface of a rectangular block body, and block soil is formed in each of the peripheral recesses. It is a concrete block for vegetation characterized by having a base soil and vegetation consisting of.

By configuring as described above, even when the construction slope is soiled with a concrete block, it is possible to reduce the exposed portion of the background of the concrete block, and it becomes possible to plant vegetation in a wide area range. Is.

"Operation" When the concrete blocks according to the present invention are piled up on the soil method surface for earth retaining work, the soil cuts into the curved tail and is held, and the protrusions formed at the four corners of the surface serve as reinforcement. Adjacent blocks on the left, right, top and bottom firmly support each other's weight to ensure earth retaining action, and since the foundation soil fitted in each recess is not weighted, it does not slip off and is inserted into the through hole. The mesh pipe has sufficient water retention capacity, and easily absorbs and permeates water and nutrients that are essential for plant growth into the surface soil soil plant organisms, creating better environmental conditions for growth and germinating plant seeds in the plant organisms. Excuse me.

[Example] Hereinafter, the present invention will be described with reference to the illustrated example.
FIG. 1 is a front view of a vegetation concrete block according to the present invention, and FIG. 2 is a side sectional view of the same.

In the figure, reference numeral 1 is a rectangular block body having a curved tail portion 2, and a central concave portion 3 is provided at the center of the surface of the block body 1.
And the peripheral recessed portions 5, 5, 5, 5 are provided at four places, leaving the raised portions 4, 4, 4, 4 at the four corners, and the through hole 6 of 20φ is bored at the center thereof. , A large number of holes 7 on its peripheral wall,
Inserting a mesh pipe 8 having holes 7, ..., Into the central recessed portion 3 and the peripheral recessed portions 5, 5, 5 and 5, granular soil having a high water-retaining capacity is dried to form a block-like base soil vegetation. Body 9
Has been inserted. The mesh pipe 8 is filled with a slow-acting solid fertilizer and a water retention agent.

In the earth retaining work, the concrete blocks of the present invention are piled up on the slope, and the wire mesh 10 is stretched on the surface with anchor pins etc., and the soil bites between the curved tail portions 2 of the rectangular block body 1 to hold it firmly. The protrusions 4, 4, 4, 4 formed at the four corners of the surface serve as reinforcement, and the blocks adjacent to each other in the vertical and horizontal directions firmly support each other to support the weight and act as an earth retaining effect. The base soil implants fitted into the recesses on the surface of the block are held in the block body 1 and are not weighted by the base soil itself, so that they do not slip off.

The base soil vegetation 9 is easy to work because it has a block shape, and it consists of granular soil that has been dried by adding a fertilizer and a water retention agent. The through hole 6 in the part takes in the water in the soil, penetrates it through the hole 7 into the mesh pipe 8 inserted therein, and further, together with the filled fertilizer and water retention agent, the base soil plant in the front surface. It is leached into the inside of the plant 9 so that plant seeds can be uniformly planted.

And, it is possible to make a concrete block, which has a bare landscape and is a landscape, into a vegetation that adapts to the surrounding natural environment.

[Advantage of the Invention] As described above, the present invention provides a central concave portion at the center of the surface of a rectangular block body having a curved tail portion, and a through hole is bored in the central portion to insert a mesh pipe. In a concrete block for vegetation in which a base soil vegetation body made of block-shaped granular soil is inserted into the central recessed portion, a protruding portion is left at four corners of the surface of a rectangular block body.
Peripheral recesses are provided at the locations, and base soil implants made of block-shaped granular soil are inserted into the respective peripheral recesses.

Therefore, even when the construction slope is soiled with a concrete block, the foundation soil planting organisms will be inserted into the peripheral portion of the surface of the rectangular block body other than the central recessed portion, so that the bare surface of the concrete block is exposed. The number of parts can be reduced, and early greening vegetation is possible in a wide area range of construction slopes.
