Abstract

PURPOSE:To pave a parking lot surface or the like and at the same time arrange for grass or the like to be grown by placing in order on a roadbed pavement blocks on surfaces of which vegetation earth housing portions are opened, filling vegetation earth into vegetation earth housing portions. CONSTITUTION:In a precast concrete made pavement block 3, plural vegetation earth housing portions 4 each size of which is small enough for an automobile tire not to fall in, are opened through on both sides, and at the same time a recessed portion and a chamfered portion are formed respectively at each perimeter center portion and square portion. Next, a pavement block 3 is placed on a pavement layer 2 on a roadbed 1 surface, and vegetation earth 7 is housed at a vegetation earth housing portion 4, and an organic fixture 8 consisting of a compressed formation containing about 70% organic substance whose main constituent is a compost, is imbedded in the earth 7, and planting stone pavement is constituted. Portions 4 are opened at block 3 surfaces or between blocks 3, and ad grass and its kind such as a planted turf can be kept on growing in these portions, paving and planting can be arranged to be conducted simultaneously.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to green paving stone pavement for paving spaces such as sidewalks, slopes where people walk, or parking lots while greening them with grass such as lawns.

0002

2. Description of the Related Art Conventionally, parking lots have been paved with gravel or asphalt because exposed ground tends to become muddy during rain, and the mud adheres to tires and pollutes nearby roads.

[0003] In addition to concrete and asphalt, sidewalks on the side of roads and walking paths in parks are often paved with paving stones.

[0004]Furthermore, there are many places in parks and other open spaces where grass such as lawns are planted for greening purposes, and visitors can freely step into them.

[0005]

[Problem to be solved by the invention] Conventional pavements such as paving stones, gravel, concrete, asphalt, etc. cover the entire road surface that people and cars step on, and other than coloring, they are made of natural grass. Some areas could not be greened.

[0006] On the other hand, in recent years, there has been a demand for greening with natural plants in housing complexes and natural parks where high-rise housing stands, but there is a problem that it is not possible to green large parking lots and sidewalk spaces. Ta.

[0007] Furthermore, when the ground surface of a plaza or the like is greened with grass such as lawns, there is a problem that the ground is trampled and exposed, especially in areas where many people pass, and becomes muddy during rain.

[0008] In view of these conventional problems, the present invention aims to provide a green paving stone pavement that can pave the surfaces of parking lots and sidewalks and at the same time allow grass such as lawns to grow thereon.

[0009]

[Means for Solving the Problems] The features of the present invention for solving the above-mentioned conventional problems and achieving the intended purpose are as follows:
Paving stone blocks made of precast concrete blocks with openings on the surface of which contain vegetation soil large enough to prevent a car tire from falling into them are laid side by side on a roadbed, the vegetation soil accommodation parts are filled with vegetation soil, and the vegetation soil is It consists of green paving stone pavement made of grasses. In addition, the present invention may be such that a similar vegetation soil storage section is provided between each of the paving stone blocks.

0010

[Function] In the green paving stone pavement of the present invention, the opening of the vegetated soil storage area is large enough to prevent the tire of a car from falling into it, so even when the car is running, the weight of the car is not applied to the vegetated soil storage area. In addition, pedestrians choose a block surface that is easy to walk on, so grass such as lawns is not trampled, and greening is maintained.

[0011]

Embodiments Next, embodiments of the present invention will be described with reference to the drawings.

1 to 4 show a first embodiment of the present invention, in which 1 is a roadbed, 2 is a sand layer on its surface, and 3 is a paving stone made of precast concrete blocks laid on the sand layer 2. It is a block. The paving stone block 3 has four vegetation soil storage areas 4 opened through it on the front and back sides, and a recessed part 5 is formed in the center of each peripheral part, and chamfered parts 6 are formed in the four corners. Adjacent paving stone blocks 3,3
... A vegetation soil storage section 4 similar to that described above is also configured in between.

[0013] Each of these vegetated soil storage portions 4 is formed to have a size such that when a car runs on it, the tires will not fall down and become unable to drive, and the vegetated soil 7 is stored inside. , organic solid matter 8 is buried in the vegetation soil 7.

The organic solid material 8 is a compression molded material containing 70% organic matter mainly composed of bagasse and bark compost.

[0015] Figures 5 to 7 show a second embodiment of the present invention, and this embodiment is a paving stone block having one vegetation/soil storage section 4 in the center and having a regular octagonal outer shape. 3
I am using a.

In any of the above embodiments, the size of the vegetation soil storage section 4 is from about 10 cm to 25 cm on a side, and the thickness of each paving stone block 3 is 1.
20cm to 150cm, and the vegetation soil is approximately 1/1/2 of the thickness.
Fill to about 3.

In the green paving stone pavement constructed in this manner, each paving stone block 3 bears the load of pedestrians and automobiles, and the vegetated soil 7 is not compacted beyond a certain level. For this reason, grasses and the like that are resistant to being trampled on can maintain sufficient reproduction in parking lots where automobiles are not frequently driven, and on sidewalks and squares where pedestrians are somewhat frequently walked.

[0018]

Effects of the Invention As described above, in the green paving stone pavement of the present invention, a vegetation soil storage section is opened on the surface of the paving stone block made of precast concrete blocks or between the surface and the paving stone block, and the size of the opening is adjusted to the size of a car. By keeping the tires to such an extent that they do not fall to the point that they cannot be driven, grass such as grass that has grown inside the vegetation soil storage area will continue to grow sufficiently on sidewalks and even on roads where cars are not frequently driven. This enabled paving and greening to be carried out at the same time.
