For example, an inverted U-shaped side gutter block type with integral construction on both sides of the walls is used, and a retaining wall block type with both side walls of separate construction is used for large-sized ones.

[Prior art and its problems]

従来の水路ブロツクは、第４図に示した側溝ブ
ロツクタイプの場合を例に説明すると、逆Ｕ字型

設けられている。 A conventional waterway block will be explained using the case of the gutter block type shown in FIG. 2 and the upper wall 3 are integrally formed, and the upper cover 4 is removably attached to the upper wall 3. The dimensions between the inner surfaces of both side walls 2, 2 are the same on the upper and lower sides, and the inner surfaces of these both side walls 2, 2 form parallel surfaces. Note that a concrete bottom plate 5 and an undercast concrete 6 are provided on the bottom surface of the block.

ところで、この従来の側溝ブロツクは、両側壁

つた。 By the way, in this conventional gutter block, since the inner surfaces of both side walls 2, 2 are parallel, if accumulated snow is thrown into the gutter when used as a snow melting channel for snow removal, the gutter block will have the same shape as shown in Fig. 5. As shown, the snow 7 does not fall easily due to the frictional resistance between the two side walls 2, 2. Furthermore, if the snow is forcibly thrown in, it will become even more firmly stuck to the side walls 2, 2, and eventually the part immersed in the running water 8 will disappear, causing the snow to lose its function as a snow melting channel. It was also on. Further, since the inner surfaces of the side walls 2, 2 are parallel, there was a further problem in that it was difficult to pull out the inner frame of the needle cage during its manufacture.

[Purpose and structure of the invention]

そこで、本考案は以上の問題点を取り除いた融
雪用水路を提供することを目的とし、その目的達
成のために次の構成をとる。 Therefore, the purpose of the present invention is to provide a snow melting channel that eliminates the above-mentioned problems, and in order to achieve that purpose, the following configuration is adopted.

即ち、上端に雪塊投入口が開口すると共に、対

ある。 That is, the snowpack inlet is opened at the upper end, and the pair of side walls are arranged in such a way that the dimension W between the inner surfaces at the upper end thereof is such that the snowpack press-fitted between the pair of opposing sidewalls falls to the lower end due to its own weight. It is characterized in that the dimension W ₂ between the inner surfaces at the lower end is larger than that of ₁ and is formed in a downward V-shaped taper.

[Example of idea]

次に、本考案の実施例を第１図及び第３図に基
づき、説明する。 Next, an embodiment of the present invention will be described based on FIGS. 1 and 3.

相違点は、第２図に示したように両側壁２，２，
１０，１０をその上方における内面間の寸法W₁
より下方における内面間の寸法W₂の方を大とし
たテーパ状に形成した点である。 FIG. 1 shows an embodiment of the gutter block type, which is an improved example of the conventional inverted U-shaped gutter block shown in FIGS. 4 and 5, and FIG. 2 is a sectional view thereof. As is clear from the drawings, the basic configuration of this embodiment is almost the same as that shown in FIGS. 4 and 5, except for the lower edge of the side wall 2, and the same reference numerals represent the same parts. By the way, the difference from the conventional example, which is a feature of this embodiment, is that as shown in FIG.
10, 10 is the dimension between the inner surfaces above it W ₁
It is formed into a tapered shape in which the dimension W ₂ between the inner surfaces in the lower part is larger.

本実施例は、この点により第２図から明らかな
とおり、上蓋４を開き、そこから投入された雪７

中に浸る部分も多くなり、速く溶けて落下するの
で、雪の投入処理作業の能率を向上できることに
なる。また、この実施例の製造に際しては、両側
壁２，２の下方における内面間の寸法W₂の方が
上方における内面間の寸法W₁より大きいので、
脱型時の内枠の引き抜き作業が容易である。 In this embodiment, as is clear from FIG. 2, the upper cover 4 is opened and the snow 7 thrown in from there is
If it moves downward even a little due to its gravity, it will separate from both side walls 2, 2, and will immediately fall into the running water 8. Therefore, running water 8
Since more parts of the snow are immersed in the snow, it melts and falls faster, improving the efficiency of the snow dumping process. Furthermore, when manufacturing this embodiment, since the dimension W 2 between the inner surfaces at the lower side of both side walls 2 and ₂ is larger than the dimension W ₁ between the inner surfaces at the upper side,
It is easy to pull out the inner frame during demolding.

なお、本実施例のように、両側壁２，２の外面

外形をテーパ状に成形した場合には、両側壁２，

ことになるから、下方部の寸法が大きいこととも
相俟つて安定度のよい設置が可能となる。 Incidentally, as in this embodiment, the dimension between the outer surfaces of both side walls 2, 2 is also increased as it goes downward. When the outer shape is formed into a tapered shape, both side walls 2,
Since the earth pressure acting on 2 generates a downward component of force, the large size of the lower part allows for highly stable installation.

を示す。 FIG. 3 shows another embodiment of a retaining wall block type used for streams, irrigation water, etc. In the figure, the retaining wall block 9 consists of side walls 10, 10 and an upper beam 11, each of which is constructed separately, and the space between each upper beam 11 on the upper surface is open. It should be noted that the bottom surface has a bottom cast concrete 12, and an undercast concrete 13 is provided on the lower surface of the side wall. Further, 14 indicates a removable handrail, and 15 indicates a road surface.

本実施例の特徴は、前述の実施例と同様、両側
壁２，２，１０，１０をその上方における内面間

を大としたテーパー状に形成したことである。 Similar to the previous embodiment, this embodiment is characterized by a tapered shape in which the dimension W ₂ between the inner surfaces below is larger than the dimension W ₁ between the inner surfaces above. It was formed in

そして、本実施例もこの点により、ダンプ等に
より大量の雪が上面の開口部より投入された場合

作業の能率を向上できる。 Due to this point, this embodiment also has the advantage that even if a large amount of snow is thrown in from the opening on the top surface by a dump truck, etc., the snow will not stick to the side walls and will easily fall into the flowing water due to the action of gravity. The efficiency of processing work can be improved.

[Effect of idea]

以上のように、本考案の融雪用水路は、対向す
る両側壁を上端部における内面間の寸法W₁より
下端部における内面間の寸法W₂の方が大きくな
るように下向きのハの字状のテーパに形成したこ

に投入された雪塊が両側壁に固着することなく、
容易に流水中へ落下するので、雪塊の投入処理作
業の能率を向上でき、除雪作業がスムーズに行え
るという効果を得ることができる。 As described above, the snow melting channel of the present invention has two opposite side walls in a downward V-shape such that the dimension W ₂ between the inner surfaces at the lower end is larger than the dimension W ₁ between the inner surfaces at the upper end. Because it is characterized by a tapered shape, this prevents snowpack thrown into the waterway from sticking to the side walls.
Since it easily falls into the flowing water, it is possible to improve the efficiency of the snowpack loading process, and it is possible to obtain the effect that snow removal work can be carried out smoothly.

又、両側壁及び上梁を一体構造にした場合であ
つても、脱型時の内枠の引き抜き作業を容易に行
えるという効果を得ることができる。 Further, even when the both side walls and the upper beam are integrally constructed, it is possible to obtain the effect that the inner frame can be easily pulled out during demolding.
