  However, in the above greening pavement construction method or pavement structure, the pavement structure is merely vegetated with grass, grass, etc. by filling the joint width between the blocks with the soil, etc. When applied to, plants such as turf and grass that have been vegetated may be stepped on and worn by the wheels of the car, and measures against heat islands and greening cannot be fully implemented.

  Accordingly, the object of the present invention is to solve the above-mentioned problems, and to plant the plant of the vegetation mat in the block body into the ground simply by fitting the greening pavement block into a predetermined roadbed area. An object of the present invention is to provide a fitting type greening pavement structure in which the plant is not stepped on by a car or a person and is worn away, and a heat island countermeasure and a greening countermeasure can be sufficiently and easily achieved.

  In order to achieve the above object, the present invention relates to a fitting type greening formed by installing a plurality of greening pavement blocks adjacent to a roadbed portion formed by digging the ground in a predetermined range and a predetermined depth. In the pavement structure, the greening pavement block includes a hollow block body having an open top and a bottom, an upper cover body having ventilation and daylighting holes provided on the block body, and the block. And a vegetation mat attached to the lower part of the body through an attachment member.

  The attachment member is preferably a skewer or string that is inserted into and attached to the vegetation mat in a skewered manner, and a holding hole for holding the skewer or string through the block body is preferably formed.

  According to the present invention, the plant of the vegetation mat in the block body can be rooted in the ground by simply fitting the greening pavement block into a predetermined roadbed area, and the plant can be stepped on by a car or a person. Therefore, it is possible to sufficiently and easily take measures against heat island and greening.

It is an expanded sectional view of the block for greening pavement which comprises a fitting type greening pavement structure. It is a disassembled perspective view of the greening pavement block. It is a schematic perspective view which shows an example of the auxiliary tool used when attaching a vegetation mat to the lower part in the block main body for greening pavements.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the accompanying drawings.

  As shown in FIG. 1, the fitting type greening pavement structure 1 according to the present embodiment has a plurality of greening pavement blocks 4 adjacent to a roadbed portion 3 formed by digging a ground 2 in a predetermined range and a predetermined depth. It is formed by installing. First, the ground is dug down to the roadbed part 5, and the roadbed part 3 having a predetermined thickness of, for example, about 300 mm is formed by filling the roadbed part 5 with planting soil. A space having a height of about 150 mm and a predetermined area formed on the road bed 3 is a space for fitting the greening pavement block 4. The above-mentioned roadbed part 3 uses fine granular black soil as planting soil, and in order to keep the upper surface of the greening pavement block 4 horizontal, it is sufficiently rolled by a roller or a compactor. Is preferred.

  As shown in FIGS. 2 to 3, the green pavement block 4 includes a block main body 6 which is a hollow molded body having upper and lower portions opened, and ventilation and lighting provided on the upper portion of the block main body 6. The upper cover 8 having the hole 7 and the vegetation mat 10 attached to the lower part of the block main body 6 via, for example, a skewer 9 as an attachment member. The block body 6 is a molded body made of steel or synthetic resin. For example, the length a is 330 mm, the width b is 330 mm, the height h is 150 mm, and the thickness t is 5 mm, and can withstand the load of a vehicle or the like. It is structured.

  At the upper part of the block main body 6 is provided an upper cover 8 having venting and daylighting holes 7. The upper cover 8 is preferably a mesh plate (expanded metal), but may be a grating. A positioning convex portion 11 that engages with the inner edge of the block body 6 may be provided on the back surface of the upper cover 8. Moreover, it is preferable that the upper cover 8 is detachably fixed to the upper portion of the block body 6 with a fixing tool such as a screw.

  A vegetation mat 10, which is a greening material, is attached to the lower part of the block body 6 via a skewer 9, which is an attachment member. As the greening material incorporated in the block main body 6, Japanese turf such as tamariu, western turf, and other low-rise plants are suitable. This greening material is formed, for example, as a vegetation mat 10 of Tamariu obtained by cutting Tamariu from a breeding site into a mat shape. The vegetation mat 10 is formed in a size that fits inside the block body 6.

  In order to attach the vegetation mat 10 to the lower part of the block main body 6 in a skewered state with the skewer 9, the skewer 9 is inserted in the lower peripheral edge of the block main body 6 to be held in the left-right direction and the front-rear direction. A plurality of holding holes 12 are formed. As a method of piercing the skewer 9 like a skewer, it may be a single row stab as shown in FIG. 3 or a cross stab. As the material of the skewer 9, bamboo or wood, which is a natural material that returns to the soil over time, is preferable. The vegetation mat 10 is mounted in the block body 6 so that the lower surface thereof is substantially flush with the lower surface of the block body 6. When the lower surface of the vegetation mat 10 is retracted upward from the lower surface of the block body 6, it is difficult to be rooted. Therefore, it is preferable that the lower surface of the vegetation mat 10 projects the same as or slightly below the lower surface of the block body 6.

  The greening pavement block 4 configured as described above may be installed in a state where it is fitted in the fitting space on the road bed 3 so that the greening pavement structure can be easily constructed. In this case, a liner may be inserted between the block main body 6 and the road bed 3 or between the block main body 6 and the block main body 6 in order to keep the green paving block 4 horizontal. The liner may be made of steel, resin, rubber, or wood. Since the lower surface of the vegetation mat 10 in the green pavement block 4 is in contact with the upper surface of the roadbed portion 3, the tamaru, which is the plant 10a of the vegetation mat 10, can be rooted and grow. In order to make it easy for the plant 10a of the vegetation mat 10 to be rooted, it is preferable that the surface of the road bed 3 is brushed with a brush-like tool in which thin rod-like protrusions are arranged.

  According to the fitting type greening pavement structure 1 described above, the plant 10a of the vegetation mat 10 grows in the greening pavement block 4 by being rooted on the ground, so that the plant of the vegetation mat 10 may be worn by a vehicle or a person. The surrounding temperature rise can be suppressed by the earth and the plant 10a rooted in the earth. Moreover, according to the said fitting type greening pavement structure 1, the space of the upper part can be utilized effectively as a place where a traffic of a vehicle, a person's walk, a parking lot, and goods are put.

  FIG. 4 is a schematic perspective view showing an example of the auxiliary tool 13 used when the vegetation mat 10 is attached to the lower part in the block body 6. The auxiliary device 13 includes a groove-shaped guide frame 14 that positions and positions the block main body 6 with the vegetation mat 10 fitted therein at one end in the longitudinal direction, and the guide frame 14 has a longitudinal direction along the longitudinal direction. It is mainly composed of a slide frame 15 having an L-shaped cross section that is slidably supported.

  A stopper frame 16 for positioning the block body 6 is provided at one end of the guide frame 14 in the longitudinal direction. The horizontal portion 15a of the slide frame 15 is provided with a handle 17 for sliding operation thereof, and the vertical portion 15b of the slide frame 15 is provided with a plurality of guides inserted through the holding holes 12 formed in the block body 6. A pipe 18 is projected. The skewer 9 is inserted into the guide pipe 18. The tip of the guide pipe 18 is cut obliquely so as to be sharpened so that it can be easily inserted into the holding hole 12.

  If the skewers 9 are set in the guide pipes 18 and the slide frame 15 is advanced to pass the guide pipes 18 from the holding holes 12 on the front surface to the holding holes 12 on the rear surface, the tip of the skewer 9 is held. Then, the slide frame 15 can be moved backward with the skewer 9 left, and the guide pipe 18 can be removed from the holding hole 12 of the block main body 6, and the skewer 9 can be easily removed from the block main body 6 and the vegetation mat 10. It can be inserted into a skewered shape, improving workability. Alternatively, the skewer 9 may be inserted into the guide pipe 18 after the guide pipe 18 has been passed through the holding hole 12 of the block body 6 without setting the skewer 9 in the guide pipe 18 in advance.
