Description

[0001]
[Technical field to which the invention belongs]
The present invention relates to, for example, a gutter block with a slit which is laid on both sides of a paved road to form a gutter.
[Prior art]
2. Description of the Related Art Conventionally, a side groove block with a slit communicates with the outside on the upper surface side and a hollow portion having a function such as a water channel inside the side groove block by a slit formed on the upper surface.
[0002]
Demand for a gutter block provided with a slit on the upper surface has been rapidly increasing in recent years.For example, gutters using the gutter block with the slit are formed and laid on both sides of a paved road. Many are found.
[0003]
Then, at the time of rainfall, a large amount of rainwater or the like that has flowed into the roadway flows into the internal hollow portion from the slit provided in the gutter, and is then drained to the drainage groove that is communicated.
[Problems to be solved by the invention]
However, in the conventional grooved side groove block, the slits are prevented from being chipped due to collision of the upper wall end portions of the side groove blocks facing each other with the slit interposed therebetween, and the load is applied to the inside of the slit so that the bottom is not formed. To prevent cracks or cracks from forming on the wall side, the gutters are made thicker as a whole, which may increase the manufacturing cost. Work was difficult.
[0004]
Therefore, in a conventional side groove block with a slit, a wedge-shaped spacing member made of synthetic rubber or synthetic resin is fitted into the slit, and ends of the side walls of the side groove block facing each other across the slit collide with each other. To prevent cracks or cracks from entering into the bottom wall by applying a load in the inward direction of the slit, thereby reducing the thickness of the side wall and the like of the side groove block. Had been proposed.
[0005]
However, the space retainer made of synthetic rubber or synthetic resin is bitten by the pressing force applied to the inside of the concrete upper wall, and as a result, pressure is applied to both side walls of the gutter block toward the slit direction. As a result, cracks or cracks may be formed at the bottom of the bottom wall or both side walls.
[0006]
Therefore, the present inventors have already filed Japanese Patent Application No. 2001-237536 to solve the problem.
[0007]
By the way, when laying a road such as a road using the gutter block in recent years, the first layer having a depth of several tens of centimeters from the surface side of the road is paved with an asphalt material having a superior drainage property. For example, when a large amount of rainfall occurs, a system is also adopted in which the first layer is permeated, the permeated rainwater is collected by a so-called water collecting pipe or the like, and drained into the hollow portion of the slit side groove block.
[0008]
However, even in the construction of a road having such a structure, in the case of laying a road having an ascending or descending slope in the longitudinal direction, the first layer is connected to the slit side gutter block. There is a problem that most of the rainwater that has permeated into the river flows downhill.
[0009]
Thus, the present invention has been devised in order to address the above-mentioned conventional problems, in which the blocks for the side gutters with slits are butt-connected to each other, and the road is laid with an upward slope or a downward slope in the longitudinal direction. Even in the case of laying flat roads without slopes, most of the rainwater that has permeated the first layer does not flow toward the specific slit gutter block, so that it penetrates all the slit gutter blocks. A water introduction groove is provided, and the outlet portion of the permeate water introduction groove is connected to the notch groove so as to be able to achieve a smooth drainage of permeate water. By covering with a mesh member, a gutter block with a slit can be provided at low cost, so that gravel and the like other than infiltration water do not enter the hollow part of the block that serves as a drain. It is an object of the present invention to be.

It is characterized by having.
[Embodiment of the invention]
Hereinafter, an embodiment of the slit side groove block according to the present invention will be described with reference to the drawings.
[0010]
The side groove block 1 according to the present invention is a side groove block 1 provided with a slit 3 on an upper surface thereof, and the slit side groove 1 is formed in a substantially cubic substantially prismatic shape.
[0011]
In the axial direction thereof, for example, a vertically long elliptical hollow portion 2 is provided. Further, a slit 3 for communicating the hollow portion 2 with the outside is provided on the upper surface portion, that is, the upper wall 11 so as to extend linearly toward the axial direction, and the slit 3 has a width of the upper wall 11. It is provided at the center position in the direction. However, the position of the slit 3 is not limited to the center position, but may be any position in the width direction.
[0012]
Further, the outer surface of the upper wall 11 is formed as a slope having a downward slope from both ends in the width direction toward the slit 3, and rainwater and the like are smoothly introduced into the slit 3 along the slope. It is configured to:
[0013]
By the way, in general, the slit in the gutter block is provided so as to completely separate the upper wall 11 from the intermediate position in the width direction. However, such a gutter block with a slit may be used (see FIG. 2). The block for the side groove with the slit may not be used.
[0014]
For example, a type in which the slits 3 are closed at both ends in the length direction of the slits 3 while the slits 3 appear as one continuous line in appearance (see FIG. 1) may be used.
[0015]
That is, the slits 3 are closed at predetermined intervals at both ends in the length direction of the slits 3.
[0016]
For example, introduction grooves 20, 20 are provided at both ends in the longitudinal direction of the slit 3, and the bottom walls forming the introduction grooves 20 are connected to the upper walls 11, 11 divided by the slit 3. Therefore, this bottom surface fulfills the function of the conventional spacing member.
[0017]
Further, the bottom surface may be an inclined bottom surface which is downwardly sloped toward the longitudinal center of the slit 3.
[0018]
This is because rainwater or the like collected in the introduction groove 20 smoothly flows along the inclined bottom surface through the slit 3 and flows into the hollow portion 2 if the inclined bottom surface is formed.
[0019]
The cross-sectional shape of the introduction groove 20 may be substantially concave, or may be substantially U-shaped.
[0020]
In any case, when the side groove block with slits 1 is laid, rainwater or the like that has flowed into the introduction grooves 20, 20 at both ends of the slits 3 of the side grooves with slits 1, flows into the introduction grooves. 20 and 20 smoothly pass through the inclined bottom surface and are introduced into the hollow portion 2 from the slit 3.
[0021]
In the case where the side groove block 1 with a slit is laid in a place having a downward slope, the side groove itself is laid with a downward slope without forming the bottom surface of the introduction groove 20 as an inclined bottom surface. Therefore, when the slit side groove block 1 is laid, rainwater or the like that has flowed into the slit side grooves 1 flows into the introduction grooves 20, 20 at both ends of the slit 3, and the introduction grooves 20, 20 smoothly passes through the bottom surface of the hollow portion 20 and is introduced into the hollow portion 2 through the slit 3.
[0022]
Next, as can be understood from the drawings, the corners between the longitudinal end surfaces of the slit side groove block 1 and the widthwise one side upper position are located at the corners from the widthwise one side upper position. Notches 4 and 4 are provided, each of which has a cut-out portion and faces the hollow portion toward both ends in the longitudinal direction.
[0023]
The formation of the notched groove 4 is not limited at all, but usually, the inner frame member for the notched groove 4 is attached to the forming mold for manufacturing the side groove block 1 with slits, and the concrete is solidified. In general, a manufacturing method in which the notch groove 4 is already formed when the mold is taken out from the mold later.
[0024]
Next, on one side of the side groove block 1 provided with the notch grooves 4, 4, a permeated water introduction groove 5 communicating with the notch grooves 4, 4 provided at both ends has an opening on one side. It is formed to have. The shape of the permeated water introduction groove 5 is not limited at all, but it is preferable that an opening 6 is formed on the one side surface over the entire length of the one side surface. This is because the opening 6 becomes an entrance for introducing permeated water after the laying of the gutter block 1.
[0025]
The opening 6 of the permeated water introduction groove 5 is covered with a mesh member 7. Further, a communicating portion between the cutout grooves 4 and 4 provided on the one side surface and the permeated water introduction groove 5 is formed as a substantially rectangular cutout as a permeated water merging adjusting groove 8, and the permeated water merged groove is formed. The rectangular opening 9 of the adjusting groove 8 is also covered with a mesh member 10 having a mesh coarser than that of the mesh portion 7.
[0026]
Thus, when the side groove blocks with slits 1 are abutted and connected and laid in the longitudinal direction, the permeated water penetrating into the ground passes through the mesh members 7 and 10, and the permeated water introduction groove is formed. 5 allows smooth introduction into the hollow portion 2.
[0027]
The underground sand and gravel are blocked by the mesh members 7 and 10 and do not enter the permeated water introduction groove 5 or the hollow portion 2.
[0028]
At the time of laying, the blocks for slit side grooves with slits 1, 1 manufactured above are abutted and connected for use.
[0029]
Then, as can be understood from the drawing, the notched grooves 4 and 4 are also butted at locations where they are connected to each other to form a large notched groove which is symmetrical with respect to the connection surface.
[0030]
Therefore, even if it is laid with a downward slope or a downward slope in the longitudinal direction, or even if it is laid in a flat state, the slit side groove block 1 having the same shape can be used.
[0031]
As a result, the rainwater that has fallen on the road penetrates into, for example, the first layer of the roadway, passes through the opening 6 covered with the mesh member 7 of the permeated water introduction groove 5, and passes through the hollow portion 2 of the slit side groove block 1. It will flow smoothly into the interior.
[0032]
Gravel and the like other than the permeated water are not blocked by the mesh members 7 and 10 and do not enter the permeated water introduction groove 5 or the hollow portion 2.
[Effect of the invention]
Thus, the present invention has the above configuration.
[0033]
And if it is a gutter block with a slit according to the present invention, for example, all the gutter blocks with a gutter so that most of the rainwater that has permeated the first layer of the road does not flow toward a specific gutter block with a gutter. A permeated water introduction groove is provided over the entire length of the one side surface, and an outlet portion of the permeated water introduction groove communicates with the cutout groove, so that a smooth drainage of permeated water can be achieved.
[0034]
In addition, since the opening of the permeated water introduction groove provided on one side of the block is covered with a mesh member, gravel and the like other than permeated water do not enter the hollow portion of the gutter block serving as the drainage groove.
[0035]
In addition, it is possible to provide a side groove block with a slit which has excellent effects at a low manufacturing cost.
