DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete structure for vegetation in which plants can be propagated on a wall surface.

[0002]

2. Description of the Related Art Conventionally, vegetation has been performed on slopes and slopes, but vegetation is considered to be difficult on vertical surfaces such as retaining walls due to problems in plant characteristics and arrangement of vegetation base materials.
However, if plants can be actively planted even on this kind of vertical surface, it is possible to devise a design, respond to environmental problems such as landscape and living environment, and also help reduce the heat island phenomenon. .

[0003] As one of the ideas, a vegetation base such as a planter or a flower pot is conventionally arranged above and below a retaining wall, and vines such as ivy are planted. As it hangs down from the lower base and crawls along the wall, almost the entire wall can be covered with green.

[0004]

However, the seed vine plants grow and proliferate while successively extending the roots on the wall surface. If the plant roots are not constantly replenished with water, they will die and become naturally rainy. Is not enough for hydration,
Requires artificial maintenance.

[0005] In addition, since the growth of plants is generally slow, if the height of the wall is high, it takes a considerably long time to cover the entire surface, and some parts that cannot be greened remain. There were also problems such as not being able to.

SUMMARY OF THE INVENTION The object of the present invention is to solve the above-mentioned problems, and an object of the present invention is to provide a vegetation in which the surface of a structure can be greened at an early stage and uniformly according to a vegetation plan, and watering becomes maintenance-free. A concrete structure is provided.

[0007]

In order to achieve the above object, a concrete structure for vegetation according to the present invention comprises a concrete wall formed on a front surface of a ground through a sheet-shaped drain filter material. A plurality of windows communicating with the filter material through water guides are opened at appropriate positions of the concrete wall, and a vegetation base on which plant seeds are planted is provided in the windows. .

The water guide may be a pipe having an upper end connected to a filter material and a lower end connected to a lower portion of the window at a predetermined gradient.

[0009] Further, the water guide portion is formed with an opening one step lower behind the window portion, and the back surface is a gap portion in contact with the filter material, and the gap portion is filled with a water retention material. (Claim 3).

[0010]

According to the above arrangement, the numerical aperture of the window can be set in consideration of the area and height of the wall and the growth rate of the plant. The groundwater permeated into the filter material on the ground side is constantly supplied to the vegetation base provided in the window through the water supply part, and the vegetation base is kept in a wet state.

When the configuration of claim 2 is adopted, the configuration for supplying water is simplified. In addition, in the case of the configuration of claim 3, it can be used as a space for plant rooting together with the function as a water storage tank.

[0012]

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIGS. 1 and 2 are a sectional view and a front view showing a first embodiment in which the present invention is applied to a retaining wall. In the figure, a sheet-shaped drain filter material 1
A concrete wall body 2 serving as a retaining wall is constructed via the.

A plurality of windows 3 are arranged in a row in the top, middle and front of the concrete wall 2 respectively.
Are formed. Each window 3 is formed in a rectangular container and has an opening formed in the same manner as a planter. Each window 3 is provided with a vegetation base 4.

The vegetation base 4 is made of ordinary culture soil or, in addition thereto, mixed with a water-absorbing fiber, a water-absorbing polymer, etc. to give shape-retaining properties. The seeds of the plant 6 and the fertilizer necessary for growth are contained therein. Etc. are dispersed in advance,
In particular, for the windows 3 provided on the front surface of the middle portion and the front surface of the lower portion, a cultivation soil having such a shape retention property is used also for prevention of collapse.

On the back side of the window 3, there is provided a water guide pipe 5 having an upper end connected to the filter material 1 and a lower end connected to the lower part of the window 3 at a predetermined gradient. And the like penetrates the ground E, flows down the filter material 1, flows through the water guide pipes 5, flows into the window portion 3, and penetrates into the vegetation base 4, so that the plant 6 planted here is formed. Water is always supplied.

If the type of the plant 6 is designed to cover the entire surface of the concrete wall 2, a vine such as ivy is desirable as shown in the figure, and the plant 6 grows while rooting on the surface of the concrete wall 2. Finally, the entire wall is covered with green.

In this case, if it is only necessary to grow at least at the position of the window 3, a plant species corresponding to the growth is selected, but at least at the time of final growth, the rooting is set to be equal to or less than the volume of the window 3. Is done.

In any case, as long as there is a supply of groundwater that has infiltrated the ground E, the groundwater is supplied from the filter material 1 through the water supply pipe 5 into each of the windows 3 to keep the vegetation base 4 in a wet state. To keep, plant 6 germinated its seeds,
Sufficient water is supplied throughout the entire period from rooting to growth.

When the concrete wall 2 is constructed, there are a method of casting in place and a method of connecting a precast concrete slab.
Can also be formed by cutting out a part of the mold.

FIG. 3 shows a second embodiment in which the present invention is applied to a retaining wall. In the drawings, the same portions as those in the second embodiment are denoted by the same reference numerals, and different portions are denoted by different reference numerals.

In the figure, a concrete wall 2 is constructed on the front of a ground E through a sheet-shaped drain filter material 1 in the same manner as in the above embodiment, and the top and lower front of the concrete wall 2 are formed. Are formed with a plurality of windows 3 in a row. Each window 3 is formed in a rectangular container and has an opening formed in the same manner as a planter. Each window 3 is provided with a vegetation base 4.

In this embodiment, an opening is formed one level lower behind each window portion 3 and a gap 10 is formed by notching the back surface of the window 3 in contact with the filter material 2. It is filled and constitutes a water guide for the window 3. The material of the water retention material 11 is a filler such as a water absorbent resin or a water absorbent fiber, and the water flowing along the filter material 1 is temporarily stored therein, and has a function as a water retention tank for the window. I have. In addition, this portion communicates with the window portion 3, and when the root 6 a of the plant 6 grows as shown in a partially enlarged manner and cannot fit within the vegetation base 4, this portion can be used as a rooting space. Like that.

Therefore, in this embodiment, even a plant having a relatively large rooting can be vegetated, and a variety of plant species for development can be selected abundantly.

[0025]

As described in the above embodiments,
In the concrete structure for vegetation according to the present invention, the numerical aperture of the window can be set in consideration of the area and height of the wall, and the growth rate of the plant, so that the vegetation corresponding to the vegetation plan is performed. This has the advantage that greening can be achieved early after wall construction.

Also, groundwater permeated into the filter material on the ground side is always supplied to the vegetation base provided in the window through the water supply part, and the vegetation base is maintained in a wet state, so that artificial water supply is not required. , Maintenance free.

When the structure of claim 2 is adopted, the structure for supplying water is simplified. Further, in the case of the structure of claim 3, there is an advantage that it can be used as a space for plant rooting, as well as a function as a water storage tank, and abundant selection of plant species for development can be made.
