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 that the vehicle is installed and the curb portion prevents the automobile from coming off the road, and rainwater or the like is guided to the waterway portion.

  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 the upper can be used as a curb and the interior can be used as a drainage channel such as rainwater, 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 normally manufactured so that the lid part and the flowing water part as the curb part can be separated to open and close the lid 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, and 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 2 c of the lid portion 2 is attached to the receiving portion 5 attached to the inner surface of the rear surface plate 3 c of the flowing water portion 3, and the front plate 3 a 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 can be used effectively because the water collection surface also serves as the road surface.

  Recently, in road structures installed on roads, there are a series of accidents in which a lid such as a manhole is flipped up when a car or the like passes and collides with another running car or the like.

The steel curb and drainage groove unit according to the proposal of the present inventors inserts a pin into pin insertion rings 8 and 9 provided with a lid portion 2 and a flowing water portion 3 respectively, or couples them with a chain or the like. Therefore, care is taken so that the lid does not fly even if the automobile collides with the lid 2 or the automobile travels on the water collecting surface 2b. However, no further safety has been considered.
