DETAILED DESCRIPTION OF THE INVENTION
Embodiments according to the present invention will be described in detail with reference to the drawings.
[0010]
1-3 show a concrete block 10 according to the present invention. The concrete block 10 is installed along the boundary region between the sidewalk 40 and the roadway 50 where the sidewalk 40 continuously moves to the upper surface of the walking road boundary block 60, and is provided in the boundary region. Is used to construct a pedestrian boundary that protrudes on the sidewalk by burying continuously along the pedestrian boundary block 60 with sheds at intervals. Here, the concrete block 10 is installed, for example, by laying foundation crushed stone, placing foundation concrete and then laying mortar, and adjacent concrete blocks are connected to each other.
[0011]
According to FIG. 1, the concrete block 10 comprises an inverted T-shaped cross section comprising a bottom slab 20 and a wall slab 30 perpendicular to the bottom slab perpendicular to the longitudinal direction along the sidewalk. The bottom plate portion 20 is composed of a bottom plate portion 21-1 on the sidewalk side and a bottom plate portion 21-2 on the side of the roadway. The bottom plate portion 21-1 on the sidewalk side has a height at which planting can be provided, and also on the roadway side. The bottom plate portion 21-2 is configured to have the same height as the walking road boundary block 60. The wall slab portion 30 perpendicular to the bottom slab portion 20 has such a height and thickness as to have the strength and the like necessary for the pedestrian road boundary to be constructed.
[0012]
This concrete block 10 is provided with a drainage hole penetrating from the sidewalk to the roadway in order to discharge rainwater or the like staying on the sidewalk 40. The drainage hole is lowered from the entrance part on the side of the sidewalk 40 to the exit part on the side of the roadway 50 so that the rainwater flow is not hindered, and the entrance part on the sidewalk side is lower than the sidewalk. Moreover, the exit portion on the road side is configured not to be lower than the roadway.
[0013]
The bottom slab portion 21-1 on the sidewalk side includes a bathtub-shaped space 22 for planting, and this space is connected to the first drainage hole 23-1 on the sidewalk side. The road is divided into second drain holes 23-2. Accordingly, the first drain hole 23-1 introduces rain water from the sidewalk 40 to the space 22, and the second drain hole 23-2 leads rain water from the space 22 to the roadway 50.
[0014]
As can be seen from FIG. 1, a single-grain crushed stone 24, a water permeable sheet 25, a guest soil 26, and a planting 27 are laid in the void 22 upward from the bottom 22-1. Therefore, rainwater from the sidewalk 40 is directly introduced from the first drain hole 23-1 into the single-grain crushed stone 24 in the space 22 through the pipe. In addition, rainwater and irrigation to the planting 27 are introduced into the single-grain crushed stone 24 through the soil 26 and the water-permeable sheet 25. The sidewalk that has reached the single-grain crushed stone 24 in the void 22 and the rainwater from planting, etc., pass through this single-grain crushed stone from the second drain hole 23-2 to the full length of the bottom plate portion 21-2 on the roadway side in the longitudinal direction. To a groove 21-21 extending therethrough. The groove 21-21 extending in the longitudinal direction connects the discharge hole 23-2 provided in each concrete block 10 and the discharge hole 23-2 of the adjacent concrete block 10 (see FIG. 3). Rainwater or the like can be discharged from the sidewalk 40 to the roadway 50 without depending on the opening position in the longitudinal direction of the shed of the roadway boundary block 60.
[0015]
In the embodiment according to FIG. 1, rainwater from the sidewalk 40 is guided directly to the single-grain crushed stone 24 through the pipe, that is, without passing through the guest soil 26, but the thickness of the single-grain crushed stone layer is reduced. When it is increased so as to be higher than the first drain hole 23-1 on the sidewalk side (not shown), it can be guided directly to the single-grain crushed stone 24 without using a pipe. .
[0016]
As can be seen from FIG. 2 when the concrete block 10 according to the present invention is viewed from the sidewalk 40 and FIG. 3 when viewed from the roadway 50 (the walking road boundary block 60 is omitted), the concrete block 10 is formed along the longitudinal direction. Although two drain holes are provided, the number of drain holes can be arbitrarily increased or decreased. In FIG. 2, a bathtub-shaped space 22 for planting is indicated by a broken line.
[0017]
The surfaces 31 and 21-11 facing the sidewalk 40 of the wall block 30 and the bottom plate 21-1 of the concrete block 10 and the surface 32 facing the roadway 50 of the wall block 30 may be arbitrarily set as decorative surfaces, respectively. it can. In the case of the surface 31 of the wall plate part 30, for example, a decorative pattern or the like can be provided in a range as indicated by a one-dot chain line in FIG.
[0018]
In order to reduce the noise from the road, the concrete block 10 can be provided with a recess in the surface 32 of the wall slab 30 facing the roadway, and the sound absorbing material 33 can be incorporated therein (FIGS. 1 and 3). As the sound absorbing material 33, known porous concrete, ceramic, asbestos, glass wool, rubber, resin and the like can be considered. In this embodiment, for example, porous concrete is used. When the concrete block 10 includes the sound absorbing material 33, since these are factory products (precast concrete products), they can be assembled at the factory. The assembly is performed by fixing with an adhesive and an anchor pin and caulking the gap. If the sound absorbing material 33 is damaged due to a collision of an automobile or the like, the sound absorbing material can be replaced on site. Furthermore, when the surface 32 of the wall slab portion 30 facing the roadway 50 is partially inclined, the sound absorbing material may be divided (33 ′, 33 ″) (FIG. 4).
[0019]
When this concrete block is applied to a straight road section of the road, the length of the surface of the bottom slab portion 21-1 facing the sidewalk coincides with the length of the surface of the bottom slab portion 21-2 facing the roadway. In the case of a curved road section, it can be applied by using a trapezoid in which the length of the sidewalk side surface is longer or shorter than the roadway side.
[0020]
