Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION This invention utilizes drainage pavement or voids of drainage pavement, and by filling these voids with various materials, various functions can be added to drainage pavement in addition to the original function of drainage pavement. The present invention relates to another function-added drainage pavement and a method of using voids in the drainage pavement.

2. Description of the Related Art In order to prevent rainwater and the like from accumulating on the road surface, the porosity is increased so that the water on the road surface is drained to the gutter etc. through this space. Paving is becoming widespread.
In the present specification, these are referred to as drainage pavements, and include sidewalks in parks in addition to roadways, and these are collectively referred to as road surfaces.

On the other hand, various marking lines and road surface markings are provided on the road surface. In order to make these markings easy to see even at night or in rainy weather, and to improve wear resistance, various road surface displaying methods are provided. Is being implemented.

For example, as shown in Japanese Unexamined Patent Publication No. 63-197705, an embedded road surface itself in which glass beads are embedded in a base material having a concave portion in the central portion and the upper surface is covered with a flat transparent body, or As disclosed in Japanese Patent Application Laid-Open No. 4-62210, there is a road surface molded article having a drainage property, which is composed of glass beads and a binder. Also, the actual Kaihei 03-1
As disclosed in Japanese Patent No. 08013, there is one in which a fluorescent paint is applied to the surface of a drainage pavement material to improve the visibility during rainfall at night.

[0005]

By the way, the drainage pavement is a pavement provided with a gap in order to prevent rainwater and the like from collecting on the road surface. It has been found that the function as drainage pavement can be sufficiently secured even if there is no void in the whole. This is because the drainage property is secured to some extent even if the pavement surface is clogged due to some dust or the like after the drainage pavement is laid.

Therefore, if the voids of the drainage pavement are filled with some material such as glass beads,
The filled material can add a new function to the drainage pavement. If the functional material is filled to such an extent that the entire void of the drainage pavement is clogged, the original function of the drainage pavement will not work, but if it is partial, such worry is unnecessary. is there.

On the other hand, the one disclosed in Japanese Patent Laid-Open No. 63-197705 has improved wear resistance in that the glass beads are protected from wear, but since the surface is flat, it can be used at night or in rain. The glass beads made it difficult to see due to the water film, and the road surface had to be dug into the desired shape during construction, which made the construction difficult.

Further, in the one disclosed in Japanese Patent Laid-Open No. 4-42210, a road surface molded article having a drainage property enhances the visibility during rainy night and the like. Must be dug, which is also difficult to construct.

Conventionally, a method of directly applying an appropriate road surface marking line to the surface of the drainage pavement has been carried out, but in this case, since the surface of the drainage pavement has many voids, There was a problem that the line could not be drawn neatly and therefore the road surface display could not be drawn clearly.
Even if this paint is mixed with glass beads, the viscosity is high because the glass beads are mixed with epoxy resin and decolorizing binder emulsion, and the glass beads do not get into the voids of the drainage pavement. Therefore, since the glass beads are projected from the road surface, the glass beads are easily peeled off from the road surface, and their effectiveness is not maintained for a long time.

On the other hand, the one disclosed in Japanese Utility Model Laid-Open No. 03-108013 is a drainage pavement material coated with fluorescent paint, so that the visibility is improved at night, but like the above-mentioned publication. The road surface must be dug during construction, which makes the construction difficult. Further, since the fluorescent paint comes out of the road surface, the effect of the fluorescent paint does not last for a long time.

[0011]

That is, it is certain that it is effective to prevent the glass beads from immersing in the water film in order to improve the visibility of the road surface display at night when it is raining. In order to improve the durability of the reflection power, it is necessary to prevent the glass beads from protruding from the road surface or to always show new glass beads even if the road surface is ground and the glass beads are also ground. It will be good.

On the other hand, when the road surface is to be displayed on an open road, it is necessary to finish the work in a short time and shorten the road closing time as much as possible. Therefore, if you dig down on the road surface or wait for the coated material to dry, you will have to block traffic for that long.

Therefore, in order to solve the above-mentioned problems, the drainage pavement with another function according to the present invention is one in which the voids of the drainage pavement are filled with a desired functional material.

Further, the method of utilizing the voids of the drainage pavement according to the present invention is such that the desired functional material is filled into the voids of the drainage pavement from the surface of the drainage pavement.

[0015]

[Function] By filling the voids of the drainage pavement with a functional material, various functions can be exhibited on the road while ensuring the function of the drainage pavement. And although these functions may be exhibited independently, it may become more effective by combining with the function of drainage.

Since the drainage pavement has a void as a passage for rainwater, if various materials are spread on the road surface to give vibration or lightly press with a roller, various materials can easily enter the void. And then filled. Further, if the entire road surface is not filled with the functional material, the function as the drainage pavement is sufficiently maintained. Therefore, the drainage function is maintained together with the new function.

For example, when displaying road surfaces, it is common to use glass beads or the like as the reflective material. However, if the voids of the drainage pavement are filled with the desired shape, the glass beads will be reflected. While functioning as a material,
Since water does not collect on the glass beads due to the drainage function, the visibility of the road surface display by the glass beads is high even during nighttime rain.

It is also possible to fill the voids with a material that does not expect a drainage function. For example, a road having a scent can be obtained by filling a space with a fragrance.

[0019]

EXAMPLES Next, examples of another function type drainage pavement and a method of using the voids of the drainage pavement according to the present invention will be described.

[Embodiment 1] A case where a road surface is displayed on a drainage pavement surface of a roadway will be described.

First, when displaying "stop", a form is prepared in which the characters "stop" are hollowed out. The form may be of any type, as long as a filling material is put in the form so that it does not leak outside. Further, a simple shape such as a pedestrian crossing or a center line can be appropriately assembled by a plate or the like on site. On the other hand, glass beads are prepared as a filling material. When displaying the character "Stop", transparent glass beads are prepared, but in some cases, colored beads such as red and green can be used. Further, the particle size of the glass beads is appropriately selected according to the size of the voids in the drainage pavement.

Then, the mold is placed on the road surface on which the word "stop" is to be displayed, and the glass beads are put in the mold. For example, if the porosity of the drainage pavement is 20% and the thickness of the road surface is 5 cm, there will be a total of 1 cm of voids in the road surface. Therefore, the glass beads are spread in the formwork to a depth of 1 cm. Since all the glass beads do not completely enter the void, it is sufficient to prepare such an amount.

When the glass beads are spread in the mold, vibration is applied to the periphery of the mold and the road surface. Then, the glass beads are filled so as to sequentially enter the voids. When the amount of glass beads on the road surface is reduced to an appropriate amount, the glass beads remaining in the mold are removed to prevent the glass beads from jumping out of the mold, and then the mold is removed. Then, the word "stop" is displayed on the road surface by the glass beads, and it is possible to prevent the unnecessary portions from being filled with the glass beads.

If only the formwork is prepared, the work can be completed in an extremely short time, and unlike painting, there is no need for drying time, and since the road surface is not dug up, there is no place to redo the pavement. The road can be opened immediately after the work is completed. If the glass beads may be scattered due to road conditions, the road surface may be appropriately coated with a transparent resin, a colorless binder, or the like, if necessary.

Since the glass beads are filled in the void over a depth of several cm, new glass beads will appear on the road surface one after another even if the road surface is ground and the glass beads are ground at the same time. Therefore, the reflection is secured for a long period of time. In addition, since the road surface itself is a drainage pavement, no water film can be formed on the road surface during rainfall, and the visibility during rainy night becomes high.

[Embodiment 2] A case where a flower (for example, a "tulip" pattern) is drawn on the drainage pavement of a sidewalk will be described.

First, a tulip form which is divided into a flower portion and a stem portion is prepared. And as a filling material,
Prepare paint-colored sand to draw tulip flowers. As the paint, general paint can be used, but if it is desired to make the pattern stand out at night, fluorescent paint or the like may be used. Prepare colored sand such as red, white, and yellow for the flower part and green for the stem. On the other hand, as a fragrance material, a granular fragrance similar to the scent of tulip flowers is prepared.

Then, the mold is placed at the position where the pattern is drawn, the flower-colored sand is put in the flower part, and the stem-colored sand is put in the stem part. In the case of sidewalks, unlike roads, the road surface hardly wears, so it is not necessary to fill the voids too deeply, so sand should be a large grain and the formwork should be several meters long.
Arrange so that the thickness is m.

When the colored sands are lined up, vibration is applied to the road surface from the periphery of the mold, so that the sands are filled so as to sequentially enter the voids. When it is confirmed that the sand in the formwork has been reduced to a certain extent and the voids have been filled, the filling operation is terminated and the sand remaining on the road surface is removed. By changing the color of the flower and doing the same, you can easily draw various tulip drawings on the road. It is also possible to give a scent to the tulip flower by sprinkling an appropriate amount of fragrance around the tulip flower and similarly applying vibration to fill the void.

The functional materials to be filled are not limited to those in the above-mentioned embodiment, but sand coated with a fluorescent paint, granular herbicides and granular snow melting agents can be used. is there.

In the above embodiment, the case where the functional material is filled for one purpose has been described, but it is also possible to use a plurality of materials at the same time to have a plurality of functions. For example, if a snow melting agent is used along with the glass beads on the center line or pedestrian crossing, the visibility will be further improved when snow is accumulated. Further, when the outer line is used together with the glass beads with a herbicide, weeds on the road shoulder can be prevented from growing, so that the outer line can be maintained in a state where it is always easily visible.

If the function as a drainage pavement is not expected, the functional material may be filled in the voids over the entire pavement surface.

[0033]

As described above, according to the drainage pavement with another function according to the present invention, since the desired functional material is filled in the voids of the drainage pavement, the original function of the drainage pavement is achieved. It is possible to add a new function to the drainage pavement by filling various functional materials into desired portions while ensuring the above.

Further, according to the method for utilizing the voids of the drainage pavement according to the present invention, the desired functional material is filled into the voids of the drainage pavement from the surface of the drainage pavement.
Drainage pavement The road surface after pavement can be filled with the functional material by a simple method, and since the functional material is filled in the voids of the drainage pavement, the effect of the added function can be secured for a long period of time.

When a reflective material such as glass beads is used for road surface display, since the road surface itself is a drainage pavement, it is possible to prevent a water film from forming on the road surface during rainfall, and thus to visually confirm it during nighttime rain. It also has the effect of ensuring safety and contributing to traffic safety.
