Description

  The present invention relates to a vegetation pavement structure suitable for a parking lot, a park road, and the like, and a vegetation pavement block for constructing the vegetation pavement structure.

As described in Patent Document 1 below, there is known a vegetation pavement block that has an opening that penetrates the front and back sides, and a plurality of openings are continuously laid and vegetation is applied to the opening.
Utility Model Registration No. 3025326

This type of vegetation pavement block fills an opening with a vegetation base material, and plants such as turf on the vegetation base material to grow, but has the following problems.
(1) Since all the openings must be planted, the planting operation is extremely complicated.
(2) Plants are heavily damaged and wither in places where there is a lot of traffic, and once they die, they will not recover unless they are planted again.
(3) On the other hand, weeds grow in places where there is little traffic, making it difficult to see.

  The present invention improves the above-mentioned problems, is easy for planting plants, is suitable for plant growth and growth, and has a vegetation pavement block and vegetation in which the difference in plant growth between places with high and low traffic is small. The challenge is to develop a pavement structure.

[Claim 1]
The present invention has a vegetation pavement block that has openings that penetrate through the front and back sides, and a plurality of the openings are continuously laid and vegetation is applied to the openings, and has at least one groove on the upper surface from the openings to the outside. The vegetation pavement block is characterized in that the upper space of the opening of adjacent blocks communicates with each other when the blocks are laid.

[Claim 2]
Further, the present invention is the vegetation pavement block according to claim 1, wherein the vegetation pavement block has a plurality of the openings, and has a groove on the upper surface that communicates with the upper space between the openings.

[Claim 3]
Further, the present invention is the vegetation pavement block according to claim 1 or 2, wherein the groove has a width of 2 to 5 cm and a depth of 0.5 to 2.5 cm.

[Claim 4]
Moreover, this invention lays down the vegetation pavement block in any one of the said Claims 1-3 continuously, fills the said vegetation base material in the said opening part, and makes a plant grow on this vegetation base material. It is a characteristic vegetation pavement structure.
In the present invention, the vegetation base material includes all materials that form a floor on which plants can grow by rooting, such as ordinary earth and sand and humus.

[Claim 5]
Moreover, this invention is the vegetation pavement structure of the said Claim 4, The said plant is an Iwadaresou, The vegetation pavement structure characterized by the above-mentioned.
In the present invention, the scallop includes all plants belonging to the genus Solanumaceae.

Since the present invention is configured as described above, the plant stems and roots vegetated in the openings reach the other openings over the grooves and grow there, so that the growth of the plants is promoted.
In addition, it is not necessary to vegetate all the openings (for example, vegetation is made in one opening for every five openings), and vegetation work becomes extremely easy.
In addition, even if the plant in the opening is damaged by the traffic of the car, the stems and roots grow from the adjacent opening, so it can be regenerated without vegetation again. The difference in overgrowth is reduced.

The appropriate width of the groove is 2 to 5 cm. If the width is less than 2 cm, the effect of the stems and roots coming from the adjacent opening is small, and if the width exceeds 5 cm, the tire of the passing car will step on the stems and roots on the grooves. This may interfere with plant growth.
The appropriate depth of the groove is 0.5 to 2.5 cm. If the depth is less than 0.5 cm, the effect of stems and roots coming from the adjacent opening is small, and a depth exceeding 2.5 cm is unnecessary. In addition, the strength of the block may be weakened.

  The plant to be vegetated in the present invention is preferably a plant such as sardine or lawn in which stems and roots grow on the ground surface or near the ground surface. Iwadareso has a long and thin stem, branches at the base and crawls the surface of the ground, descends from the roots and grows vigorously, and the ground surface is densely covered so that weed growth is also suppressed. In addition, almost no mowing work such as lawn is required, it has excellent resistance to treading, and adapts from acidic soil to alkaline soil.
