Description

[Detailed description of the invention] "Field of industrial application" This invention relates to the structure of waterways used as side ditches in snowy areas.

"Prior Art" FIG. 5 is a diagram showing an example of a conventional waterway. This waterway has a space 2 inside a waterway main body 1. In this channel, water flows through the space 2. By the way, when this waterway is used in a snowy country or an area with a lot of dead leaves, there is a risk that the space 2 will be blocked by snow, dead leaves, etc., and the flow of water will be stopped. Therefore, as a waterway used in the above-mentioned areas, a waterway as shown in FIG. 6 that does not stop the flow of water under any circumstances has been conventionally provided. The waterway 3 shown in FIG. 6 is composed of a waterway main body 4 and a water-permeable partition plate 5. The waterway 3 shown in FIG. The water channel main body 4 has an overhanging portion 6 for supporting a water-permeable partition plate formed on the inner side surface, and a groove 7 formed on the inner bottom surface. The water-permeable partition plate 5 includes
A locking portion 8 that locks onto the projecting portion 6 of the waterway main body
A plurality of holes 9 for water permeation are formed. The water-permeable partition plate 5 is engaged between the projecting portion 6 and the groove 7 and is provided so as to define a space inside the water channel body 4. As described above, waterway 3 is
Inside the water channel body, there is a space 10 outside the diaphragm plate and a space 11 defined by the water channel body 4 and the diaphragm plate 5. In this waterway, even if snow, dead leaves, etc. accumulate in the space 10 when used in the above-mentioned area, the water that passes through the water permeation hole 9 among the water flowing through the space 10 flows through the space 11. ,
Water flow is maintained.

"Problem to be solved by the invention" By the way, in the above-mentioned conventional waterway, when the water flowing through the space 10 permeates into the space 11, the water can only pass through the water permeation hole 9. The water permeates through only a few points, and the efficiency of water permeation is poor. In addition, since the material used for the partition plate was steel, it had the disadvantage of being susceptible to rust.

"Means for Solving the Problem" This invention provides a permeable partition plate inside the waterway body that divides the internal space into a plurality of compartments along the width direction of the waterway body. In a waterway in which the main flow passes outside the board and the water that permeates from the central space is allowed to flow, gravel hardened with adhesive to form a water-permeable board is used as a partition board inside the waterway. It is characterized by
