Description

  The present invention relates to a drainage device installed along a road shoulder, a boundary between a roadway and a median, an edge of a large-scale facility site, or the like.

Usually, a drainage groove for discharging rainwater on the road surface is provided at the road shoulder or the boundary between the roadway and the median strip. The drainage ditch is often covered with a lid to prevent intrusion and derailment of garbage.
Conventionally, various drainage devices for easily forming such drainage grooves have been proposed.
For example, Patent Literature 1 includes a side groove having an opening formed in an upper portion of a water channel, a grating portion disposed in the opening portion of the side groove, and a light shielding portion disposed between the water channel and the grating portion of the side groove. A side groove structure is described in which water flowing from the grating portion is dropped into the water channel by the light shielding plate, and the light inserted into the water channel is blocked.
When the conventional side groove structure is used, sunlight is blocked by the light shielding portion, so that weeds are unlikely to grow in the side groove.
However, since the earth and sand accumulates in the part where the water flows inside the gutter, there is a concern that the water flow is blocked by the earth and cannot be drained smoothly. Also, when the concrete shrinks and a gap is formed between the outer surface of the side groove and the road, it is difficult to prevent weeds from growing in this gap.

In Patent Document 2, in order to prevent the growth of weeds from the gap between the curb of the sidewalk and the pavement, or from the joint between the pavement, a belt-like weed that is buried under the pavement and closes the gap. A tool is disclosed.
Since this weed protector is installed under the pavement material, there is a distance from the pavement material to the shielding part or bottom plate part of the weed protector, and it is not possible to prevent weeds from taking root in the soil that entered through the gap. was difficult.

Therefore, the water flow that mainly passes through the corners of the water receiver is not easily blocked by the earth and sand, and is smoothly drained.

Furthermore, the light that enters through the water collecting hole is blocked by the light shielding plate and the internal weedproof plate, and the internal weedproof plate that prevents the growth of weeds overhangs, thus preventing weeds from breeding in the water receiving body. Can do.
Even if there is a gap between the front plate of the water receiver and the concrete placed on the front side of the front plate, it is blocked by the external weed plate and the weeds in the ground cannot grow. Since it is provided on the upper part of the board, even if soil accumulates on the external weed prevention plate through the gap, it is very shallow and weeds entering from the gap are less likely to take root.

According to the invention which concerns on Claim 2, muddy water can fall rapidly by the inclination of a horizontal piece, and it can prevent that earth and sand accumulate on a horizontal piece.
According to the invention of claim 3, not only the strength of the external weed prevention plate is increased, but the weeds to be extended are guided downward and bent, so that the weeds bend sideways and then extend to the ground. No.
According to the invention which concerns on Claim 4, even if the seed of weeds is mixed in the ground of the surface side of a water receiver, it will be prevented by the lower weed prevention plate and will not grow easily.
According to the invention which concerns on Claim 5, the intensity | strength of a water receiver can be raised.
