Field of the Invention The present invention relates to a gutter structure, and more particularly, it corresponds to both a road gradient and a water gradient, and moreover, the water gradient can be an arbitrary gradient with respect to the road gradient, and The present invention relates to a gutter structure which is lighter in weight than the gutter of and is easy to install.

Description of the Related Art Conventionally, as a gutter structure installed on a side portion of a road, as shown in FIG. 1, a gutter structure having an upper wall and a lower wall which are horizontal is generally used. However, the place where the gutter structure is installed is not always on a flat surface, but rather, the gutter structure must be installed on an inclined surface because of the characteristic of the Japanese land that there are many ups and downs of the ground.

る。When the conventional gutter structure as described above is installed on such an inclined surface, it is necessary to install the upper wall of the gutter according to the slope of the road. In this case, the slope of the ground changes. When installed, there is a problem that a gap is created between the gutter structures during construction, as shown in FIG. Further, in the above-mentioned conventional type gutter, since it cannot be installed perpendicularly to the excavation groove, there is a problem that it takes time to install it. Moreover, when the above-mentioned conventional gutter structure is installed on an inclined surface, the water gradient formed by the lower wall of the gutter becomes equal to the road gradient, but in this case, especially in a place where the road gradient is steep, the water flow rate due to rainfall etc. When it increases, the outflow velocity of the running water becomes steep, and as a result, the running water may flow into the downstream at once, and the running water may overflow.

However, conventionally, the gutter structure corresponding to the road gradient is merely the one in which the gutter upper wall 11 is inclined. However, as a result, the thickness of the gutter upper wall 11 becomes thicker toward the upper part of the inclined surface. There is a problem that the weight of is heavy. In addition, in this gutter, the water gradient formed by the inner bottom surface 12a of the gutter lower wall is
Since it is horizontal with respect to the ground, the outflow speed of the running water is reduced as compared with the case where it is inclined with respect to the ground, which is not preferable.

Therefore, it is possible to prevent the wastewater from overflowing downstream due to an increase in the flow rate of the wastewater. Further, in the gutter structure of the present embodiment, since the wall thicknesses of the upper wall and the lower wall are constant along the length direction of the gutter structure, as shown in FIG. 3, the member becomes thicker as it goes upstream. The weight of the gutter structure is reduced compared to the gutter.

While the side groove structure 1 of the present embodiment is generated.
Then, as shown in FIG. 7, even if the inclination changes, the ditch structures can be installed so as to be in contact with each other. In addition, when installing the gutter structure in the excavation groove, in the conventional gutter structure, fishing is done with a crane or the like, first one end is installed so as to contact the excavation groove, and then the other end is contacted with the excavation groove. In contrast to the two-step work of installing like this, in the case of the side groove structure 1 of the present embodiment,
Since it can be immediately installed in the excavation groove by catching it with a crane or the like and dropping it vertically to the excavation groove as it is, the installation work can be simplified.

For example, the height of the gutter structure can be various sizes depending on the installation location. The overall shape of the gutter structure is not limited to the box type as in the above embodiment, but may be divided into several units and combined. Also,
Since it is installed on the road shoulder, the upper wall or the side wall of the gutter may be provided with an earth retaining block or a distinguishing block for distinguishing the sidewalk from the roadway. In addition, in order to efficiently remove rainwater from the road surface, water drainage holes are provided on the left and right side walls, or drainage slits are provided on the upper wall of the gutter, and the upper wall surface is inclined toward the center. It can also have a different structure.

By doing so, the outflow rate of the drainage can be adjusted regardless of the inclination of the installation location, so that the drainage can be prevented from overflowing in the downstream direction. Moreover, since the wall thickness is constant over the length direction of the gutter structure, the weight can be reduced as compared with the conventional gutter, and since it can be installed vertically to the ground, it can be easily installed in the excavation groove.
