Description

  The present invention relates to a steel curb and drainage groove unit that can be installed on a shoulder of a road, a median strip, or the like to guard an automobile from coming off the road and drain the road.

  As a method of preventing the car from coming off the road or draining rainwater etc. on the road surface, it is installed on the road shoulder and the median strip and a gutter is formed to prevent the car from coming off the road by the curb, rainwater on the road surface, etc. A curb and drainage groove unit formed as a steel hollow body as a whole with a curbstone with a tire support part on the shoulder and a center separation band and a waterway part with a drainage groove on the inside. It is well known to install it, prevent the car from coming off the road by the curb, and guide rainwater to the waterway.

  The former method has been practiced since ancient times, but has been practiced since the inventor proposed in utility models and patents to be described later.

  According to the latter method, it is possible to easily make a guard row using a steel curb and drainage groove unit, and use the curbstone on the upper side and use the interior as a drainage channel for rainwater, etc. There is no need to separate the curb installation and drainage installation work separately from the concrete curb. Therefore, there is a remarkable spread. Moreover, in a road bridge, since the steel curb and drainage unit is a hollow body, the dead load can be reduced.

  In these proposals, the steel curb-cum-drainage unit is usually manufactured so that the cover part and the flowing water part as the curb part are separable for opening and closing the cover part. For example, as shown in FIG. The lid portion 2 is formed of a tire support surface 2a, a water collection surface 2b, and a top plate 2c. The water flow portion 3 is formed of a front plate 3a, a bottom plate 3b, and a rear plate 3c. Being done. When the tire support surface 2a is formed on an inclined surface, there are some that also serve as the upper surface plate 2c. Reference numeral 7 denotes a reinforcing rib of the lid portion 2 attached to the back surface of the tire support surface 2a of the lid portion 2 and the back surface of the upper surface plate 2c.

  In this example, the lid portion 2 and the flowing water portion 3 are configured such that the end portion of the upper surface plate 2c of the lid portion 2 is attached to the receiving portion 5 attached to the inner surface of the rear surface plate 3c of the flowing water portion 3, and the front plate 3a of the flowing water portion 3. The water collecting surface 2b of the lid portion 2 is placed on the receiving portion 6 attached to the inner surface of the lid portion 2. Reference numerals 8 and 9 denote pin insertion rings, respectively, which are inserted to prevent the lid portion 2 from being detached from the flowing water portion 3.

  A plurality of steel curb and drainage grooves units formed in this way are installed at the road shoulder and the boundary between the roadway and the sidewalk of a general road to form a guard row. The installed steel curb and drainage ditch unit can effectively use the road width because its water collection surface also serves as the road surface.

  In order to use the road width effectively, the depth of the tire support portion should be short. Further, the depth of the water collecting surface is preferably shorter in the same manner when considering the load of the automobile.

However, when a large amount of rainfall occurs, if the depth is short, the width of the flowing water portion is small, and thus draining is difficult. On the other hand, increasing the depth of the tire support and increasing the width of the running water section narrows the road width.

  The present invention intends to solve the difficulty of draining a large amount of rainwater and the like in the steel curb and drainage groove as described below.

  The steel curb / drainage unit according to the present invention is a steel curb / drainage unit having a lid as a curb having a tire support and a water collection surface and a water flow as a drainage groove. The bottom of the water flow part is wide in the road width direction, and the plate-like reinforcing ribs are perpendicular to the surface of the water collecting surface and attached to the lower surface of the water collection surface at predetermined intervals. It is characterized by being attached at predetermined intervals.

  Since the present invention is configured as described above, it has the following effects.

  Since the water collecting surface of the lid part and the bottom surface of the water flowing part as the drainage groove are wide in the road width direction, the width of the water channel is increased and a large amount of water can be handled. In addition, since the reinforcing ribs are attached to the lower surface of the water collecting surface at a predetermined interval, the strength against the applied load is reinforced. The reinforcing ribs are attached so that the ends are in the direction of running water, so that the flow of collected water is not hindered. Since the reinforcing rib is attached to the lower surface of the water collecting surface, it does not hinder the cleaning of the water channel by opening the lid. A reinforcing plate is attached to the back surface of the water collecting surface of the lid, and a reinforcing rib is attached thereto, thereby further reinforcing the water collecting surface.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 is a plan view of a steel curb and drainage groove unit according to the present invention, FIG. 2 is a front view thereof, and FIG. 3 is a side view thereof.

  The steel curb and drainage groove unit 1 includes a lid portion 2 and a flowing water portion 3.

  The lid portion 2 is formed by a water collection surface 2b that is substantially flush with the road surface, a tire support portion 2a that rises from the water collection surface 2b, and an upper surface plate 2c that extends from the upper end in the direction opposite to the water collection surface 2b.

  The flowing water part 3 is formed by a front plate 3a, a bottom plate 3b, and a rear plate 3c that form a flowing water channel. Receiving portions 5 and 6 of the lid portion 2 made of L-shaped steel are attached to the inside of the upper end of the rear plate 3c and the front plate 3a of the flowing water portion 3.

  The water collecting surface 2b of the lid portion 2 is larger than the depth width of the curb portion of the lid portion 2, and in this embodiment is set to be twice or more, and the bottom surface plate 3b of the water flow portion 3 is increased accordingly. It is wide in the road width direction.

  Reinforcing plates 4 are attached to the lower surface of the water collecting surface 2b of the lid portion 2 so that the surfaces face each other at predetermined intervals, and plate-shaped reinforcing ribs 10 are attached to the reinforcing plate 4 at the ends in the flowing direction. It is attached like this. The lid 2 is provided with a water collection hole 2e between the water collection surface 2b and the tire support 2a, and an opening / closing hand hole 2f as necessary. Reference numeral 7 denotes a reinforcing rib of the lid portion 2 attached to the back surface of the tire support portion 2a of the lid portion 2 and the back surface of the upper surface plate 2c.
