There are many dual-purpose types provided with a recess inside the side wall so as to have both a function of flowing snow and a function of melting snow. For this reason, the conventional snow gutter is a snow gutter having a cross-section that is slightly larger than the calculation, resulting in problems such as poor construction work for excavation and installation and an increase in cost such as product cost. When the bottom formed in the running water gradient is formed of cast-in-place concrete, the channel surface cannot be formed smoothly. Therefore,
Since the sweeping power of snow and water is weakened, it is necessary to flow a large amount of water or to form a steep slope at the bottom.

[0004] When the water temperature decreases, seawater and river water (around +2 degrees Celsius) are used in the northern region. However, a slight change in the atmospheric temperature causes the snow in the snow ditch to solidify and stop flowing. Is overflowing on the road. Since the basin is a square, the water flow migrates inside the basin, the running force (sweep force) weakens, the snow clogs and solidifies, and the water often overflows from the top of the basin, which is harmful to traffic safety. is there.

[0017]

[Effect of the Invention] Without adopting a structure for melting snow for flowing a large amount of water,
Since it is limited to snowfall grooves with only the snowfall function, it is possible to produce snowfall grooves that fully perform the snowfall function by combining a small amount of water and fittings with a slight runningwater gradient. Also, the cross section of the snow gutter may be a calculated value, and the cost can be reduced along with both the workability and the product cost. Since the sliding material is provided on the inner flow path surface of the lower block, the friction between snow and water and the snow drift can be made smaller than in the case of concrete. As a result, a sweeping effect about 2.6 times that of a conventional snow drift is exhibited. The slope of the upper block in the snowfall ditch is a gradient adjustment operation using only the fittings, and since the fittings adjusted in advance are used, the workability is good. In addition, the work of cast-in-place concrete is eliminated, so that the construction period can be shortened and the cost can be reduced.

In the case of a divided snowfall groove using a combination of a pit and an invert cone, the pit and the invert cone formed in a flow path having a predetermined angle may be fitted to the pit in common. The number of parts can be reduced. Further, it is easy to change the flow path since the inverted cone formed in the flow path having a predetermined angle may be fitted, and the construction period of the snowfall groove can be remarkably reduced. In the case of a basin in which the flow path is integrally formed inside the basin, the bottom surface of the side groove is a precast integrally molded product while having a function as a free slope side groove, and the workability is good. In the case of using such a material, since it is long and has few seams, the snowfall effect can be further improved. In addition, because the inner surface structure is pre-inverted, the effect of snowfall is good, the loss of flow velocity is small, and the amount of water is small,
Since the slope of the snowfall can be small, it leads to cost reduction.
