Description

  The present invention relates to a greening road surface structure that prevents a heat island phenomenon, and more particularly, to a greening road surface structure that can be suitably used for a parking lot, a park square, a sidewalk, and the like.

For example, the use of lawns in parking lots has been attracting attention in recent years as a countermeasure for heat island because it has the effect of lowering the temperature of the ground surface.
As a method of constructing such a greening road surface, a method in which a large number of holes that open upward are formed on the upper surface of a concrete block or a synthetic resin molded body, and a plant is vegetated by filling each hole with soil. Known (see Patent Documents 1 and 2).
In addition, a method is also known in which a large number of concrete blocks are laid out with a joint spread, and the joint is filled with soil, and a plant is vegetated on the soil. Various spacers for securing the joint are also proposed. .

However, in the conventional green road surface structure described above, even if the ground is greened to a certain extent to alleviate the heat island phenomenon, the concrete block itself has heat, and a new concrete block is required. There is a problem that an artificial material such as a molded body made of synthetic resin or the like must be used.

  Moreover, by mixing and filling the water sludge into the soil, the water sludge as waste can be effectively used.

  Hereinafter, an embodiment of a greening road surface structure of the present invention will be described based on the drawings.

1 to 2 show an embodiment of a greening road surface structure of the present invention.
This tree planting road surface structure cuts thinned wood into a predetermined length to form a thinned wood block 1 and has a predetermined shape into which the thinned wood block 1 can be inserted, specifically, a frame body partitioned into a lattice. A spacer 4 for inserting the thinning material block 1 is formed, the thinning material block 1 is inserted vertically into each partition frame 41 of the laid spacer 4, and the gap between the thinning material blocks 1 is filled with soil 2 to plant 3 is vegetated.

The thinning material block 1 is formed, for example, by cutting thinning materials such as cedars and bushes having a diameter of about 7 to 8 cm to a length of about 15 cm.
The thinned wood block 1 can be laid, for example, about 15 cm of crushed stone 5 on a conventional ground and laid on the crushed stone 5 in a square matrix or other arrangement.
In this embodiment, about 100 thinned wood blocks 1 are laid per 1 m ² .
In addition, when laying the thinned wood block 1, in order to prevent the thinned wood blocks 1 from becoming uneven due to long-term use, the crushed stone 5 is laid, and the surface is compacted and leveled to some extent by rolling, etc. Further, it is desirable to lay a water-permeable sheet (not shown) such as a synthetic fiber nonwoven fabric, and lay the thinning material block 1 thereon.

On the other hand, in this embodiment, the spacer 4 is formed by vertically fixing two mesh frames 42 in which reinforcing bars are welded in a lattice shape at predetermined intervals. By doing so, for example, joint portions 21 having a width of about 3 cm are formed between the partition frames 41. The joint portion 21 can be arbitrarily set in width, thereby adjusting the area ratio for plant growth.
The lower portion of the spacer 4 is provided with a leg portion 43 that supports the spacer body by lifting it from the laying surface, and the thinned wood block 1 protrudes from the upper surface of the spacer 4 by, for example, about 2.5 cm. Inserted and laid.
In addition, it is not necessary to insert the thinning material block 1 in all the spaces partitioned by the grid of the spacer 4, for example, the thinning material block 1 can be inserted at intervals so as to form a checkered pattern. By this, it is possible to adjust the area ratio for plant vegetation.
Furthermore, a ring-shaped connecting member 44 for fixing the adjacent spacers 4 is provided at the corners of the spacers 4 so that the plurality of spacers 4 can be easily connected and laid.
The ring-shaped connecting members 44 are provided with different heights so that adjacent members overlap each other, and a wedge-shaped pin (not shown) can be driven into and fixed to the stacked rings.
In the present embodiment, the dimensions of the partition frame 41 are 8 cm square in length and width, about 10 cm in height, and the height of the leg portion is about 2.5 cm.

Moreover, although the soil 2 is filled in the gap | interval of the laid thinning material block 1, in this Example, it mixes and fills the soil 2 with a water retention material and clean water sludge.
Among these, as the water retention material, any form of water retention material such as powder, granules, and liquid can be used, and in particular, a liquid water retention material capable of arbitrarily adjusting the water retention performance. For example, a liquid water retaining material made of sodium polyacrylate (specifically, “Espec” (trade name) manufactured by Toyobo Co., Ltd.) can be preferably used.
Thereby, while maintaining the water | moisture content in soil moderately and improving the growth of the plant 3, the water-sewage sludge which is a waste material can be used effectively.

Thus, the greening road surface structure of the present embodiment cuts the thinned wood into a predetermined length to form the thinned wood block 1, and the thinned wood block by the frame body that is partitioned into a predetermined shape into which the thinned wood block 1 can be inserted. Because the thinning material block 1 is inserted vertically into each partition frame 41 of the laid spacer 4 and the space between the thinning material blocks 1 is filled with soil so that plants are vegetated. In addition to controlling the temperature rise of the ground with plants and thinned wood, effectively preventing the heat island phenomenon, and using the thinned wood block 1 to reuse the existing waste and contribute to environmental protection Furthermore, by inserting the thinned wood block 1 into the partition frame 41 of the spacer 4, the thinned wood block 1 can be prevented from being displaced and dented and the thinned wood block 1 can be laid carefully. It can facilitate the work.
And by providing the connection member 44 which fixes the spacer 4 adjacent to the outer peripheral part of the spacer 4, the some spacer 4 can be connected and laid easily.

  As mentioned above, although the Example of this invention was described, the structure of the greening road surface structure of this invention is not limited to description of this Example, For example, a spacer 4 is used as a board | plate material, a synthetic resin molding material, and other things. The partitioned space into which the thinning material block 1 formed by the members or formed in the spacer 4 is inserted is formed into a shape other than the lattice shape, for example, a parallel frame shape in which the vertical frame or the horizontal frame is omitted, and the thinning material block 1 It is possible to make appropriate changes within a range that does not depart from the gist of the invention, such as inserting them in close contact with each other or forming a shape constituting an arbitrary pattern.

  The greening road surface structure of the present invention suppresses the temperature rise of the ground by plants and thinned wood, effectively prevents the heat island phenomenon, and uses the thinned wood block to recycle the waste that exists in the environment. Since it has the characteristic of contributing to protection, it can be suitably used for parking lot applications, and can also be used for, for example, park squares and sidewalks.

It is a perspective perspective view which shows one Example of the greening road surface structure of this invention. The greening road surface structure of the same Example is shown, (a) is a top view, (b) is a partial expanded longitudinal cross-sectional view.
