TECHNICAL FIELD OF THE INVENTION
The present invention relates to a structure of a drainage groove for a road surface installed on a road or a parking lot, and more particularly, to a structure of a drainage groove for a metal surface buried in a road surface made of permeable asphalt or the like.
[0002]
[Prior art]
BACKGROUND ART In recent years, permeable pavements made of permeable asphalt or the like have been frequently used in order to improve drainage of a road surface such as a road. In such a permeable pavement, rainwater or the like on the road surface flows along the upper surface of the road surface, penetrates into the pavement portion, and is collected and drained by the road surface drain.
[0003]
As a conventional structure of this type of drainage for road surface, a concrete drainage gutter body is laid on the road surface to collect rainwater and the like from the surface of the road surface, and at the same time, to introduce water permeated into the permeable pavement part. A possible structure has been proposed (for example, see Patent Document 1). In this drainage groove structure, a concrete drainage groove main body is disposed along the inside of a curb block at the end of a permeable pavement portion, and is buried so that the upper surface on the opening side is at the road surface height of the pavement portion. In addition, the drain gutter body has a receiving step on which the end of the permeable pavement is laid, and a slit capable of collecting water is provided in the receiving step to prevent rainwater or the like seeping into the permeable pavement. It is configured to collect water.
[0004]
By the way, in this kind of drainage ditch structure, it is inevitable that fallen leaves, earth and sand, dust and the like enter and accumulate in the water channel, and there is a tendency that drainage deteriorates with long-term use. However, in a drainage structure made of a concrete product that has been widely used, it is impossible or difficult to open a water passage for inspection and cleaning. There is no alternative but to force the water to flow and forcibly wash away the sediment and the like in the water channel. However, it is difficult to completely remove sediment and the like in the water passage by the force of water such as a hose, and there is a limit in terms of efficiency. Further, the cleaning work is also complicated. In addition, since the lower surface of the water passage is formed of concrete, soil and the like are likely to accumulate, but there is a concern that the concrete portion may be damaged. Furthermore, the drainage groove member buried in the road surface is not easy to remove, and when the drainage function is extremely deteriorated or the drainage groove member is damaged, the pavement must be broken down to perform the work.
[0005]
On the other hand, in the conventional drainage ditch structure, concrete products are mainly used as described above, but this type of concrete product is heavy, and transportation and construction work on site are complicated. On the other hand, large-scale civil engineering work is required for repair and replacement, and there are problems in terms of construction period and cost.
[0006]
Furthermore, as the drainage structure as described above, it may be desired that the water channel buried inside the road surface has a large diameter, but the inside of the pavement road surface is a portion to which the load of the passing vehicle is applied, There was a problem in increasing the size of the drain itself due to durability issues and the like.
