Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art Conventionally, vegetation on slopes and slopes has been performed, but vegetation on vertical surfaces such as retaining walls is considered to be difficult 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 will be possible to devise a design, address environmental problems such as landscape and living environment, and help reduce the heat island phenomenon. .

As one of the measures, conventionally, vegetation bases such as planters and flower pots are arranged on the upper and lower portions of the retaining wall, and when vine plants such as vines are planted, the upper bases are grown as they grow. It is possible to cover almost the entire wall with green by hanging down from the bottom base and climbing along the wall from the lower base.

[0004]

However, the vine plant grows and propagates while roots are successively placed on the wall surface, and unless the roots of the plant are constantly replenished with water, it will die and natural rainfall will occur. Because it will not be enough to rehydrate,
Requires artificial maintenance.

In general, since the growth of plants is slow, if the height of the wall surface is high, it takes a considerably long time to completely cover the entire surface, and some areas cannot be replanted. There were also problems such as not being able to.

The present invention has been made to solve the above problems, and the purpose thereof is to make the surface of a structure early and evenly green according to a vegetation plan, and to make maintenance free of watering. A concrete structure for use is provided.

[0007]

In order to achieve the above object, the vegetation concrete structure of the present invention constructs a concrete wall body on the front surface of the ground through a sheet-shaped drainage filter material, and It is characterized in that a plurality of windows communicating with the filter material via a water conduit are opened at appropriate positions of the concrete wall body, and a vegetation base on which plant seeds are planted is provided in the windows. .

The water guiding portion may be a pipe in which an upper end portion communicates with a filter material and a lower end portion communicates with a lower portion of the window portion at a predetermined gradient (claim 2).

Further, the water guiding portion is an opening formed at a lower level behind the window portion, and the back surface is a void portion in contact with the filter material, and the void portion may be filled with a water retaining material. Yes (Claim 3).

[0010]

According to the above construction, the numerical aperture of the window can be set in consideration of the area and height of the wall body and the growth rate of plants. Groundwater that has penetrated into the filter material on the natural ground side is constantly supplied to the vegetation base provided in the window through the water conduit to keep the vegetation base moist.

When the structure of claim 2 is adopted, the structure for water supply becomes simple. Further, in the case of the structure of claim 3, it can be used as a space for rooting of plants as well as a function as a water storage tank.

A concrete wall body 2 serving as a retaining wall is constructed via the.

A plurality of windows 3 are arranged in a horizontal row on the top of the concrete wall 2 and on the front of the middle part and the front of the lower part.
Is formed with an opening. Each window 3 has a rectangular container shape like the planter and has an opening formed therein, and each window 3 is provided with a vegetation base 4.

The vegetation base 4 is a normal culture soil, or in addition to this, water-absorbent fibers, water-absorbent polymers, etc. are mixed to provide shape retention, and the seeds of the plant 6 and fertilizer necessary for growth are provided inside. Which has been dispersed in advance,
In particular, for the window portions 3 provided on the front surface of the middle portion and the front surface of the lower portion, culture soil having this type of shape retaining property is used for preventing collapse.

On the back side of the window portion 3, there is provided a water guiding pipe 5 having an upper end portion communicating with the filter material 1 and a lower end portion communicating with the lower portion of the window portion 3 at a predetermined gradient. Etc. infiltrate the ground E, flow along each water guiding pipe 5 into the window portion 3 while flowing down through the filter material 1, and permeate into the vegetation base 4 to the plant 6 planted here. Water is always supplied.

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

In this case, if it is sufficient to grow only at least at the position of the window portion 3, a plant species corresponding thereto is selected, but it is set so that the rooting is not more than the volume of the window portion 3 at least at the final growth point. To be done.

In any case, as long as groundwater that has penetrated into the natural ground E is supplied, this groundwater is supplied from the filter material 1 through the water guiding pipes 5 into the respective window portions 3 to make the vegetation base 4 wet. In order to keep the plant 6 germinated its seeds,
Sufficient water is supplied over the entire period from rooting to growth.

When constructing the concrete wall 2, there are a method of casting on site and a method of continuing the precast concrete slab, but the window 3 and the water pipe 5 are used.
Can also be formed by removing a part of the formwork from a box.

FIG. 3 shows a second embodiment when the present invention is applied to a retaining wall. In the drawing, the same parts as those in the second embodiment are designated by the same reference numerals, and different parts are designated by different reference numerals.

In the figure, a concrete wall body 2 is constructed on the front surface of the ground E by way of a sheet-shaped drainage filter material 1 similarly to the above-mentioned embodiment, and the top and lower front surfaces of the concrete wall body 2 are constructed. A plurality of window portions 3 are formed in each of the horizontal rows. Each window 3 has a rectangular container shape like the planter and has an opening formed therein, and each window 3 is provided with a vegetation base 4.

In this embodiment, an opening is formed at a lower level behind each window portion 3, and a void portion 10 whose rear surface is in contact with the filter material 2 is cut out, and a water retaining material 11 is provided in this void portion 10. It is filled and constitutes a water conduit for the window 3. The material of the water retaining material 11 is a filling material 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 functions as a water retaining tank for the window. There is. Further, this portion communicates with the window portion 3, and as shown in a partially enlarged view, when the root 6a of the plant 6 grows and cannot fit in the vegetation base 4, this portion can be used as a rooting space. I am trying.
