な問題点を解決する為の種々の対策が採られている。A snow drifting ditch is a snow dumping hole that has a culvert type snow drifting groove buried underground, and openings that open above the ground at predetermined intervals for throwing snow into this snow drifting groove. It is a snow removal facility that attempts to remove snow by using the sweep power of the flowing water (mainly using river water) flowing through the drifting snow groove. There are many examples of this in heavy snowfall areas such as the Hokuriku region. A particular problem with the above-mentioned snow drifting ditches is when the atmospheric temperature reaches extremely low temperatures, and the snow powder that is thrown from the snow dumping opening and the force of the snow as it falls becomes a problem. Formation of ice on the inner wall surface of the snow throwing opening caused by adhesion of splashes of running water,
Condensation and freezing of evaporated moisture due to the difference between the temperature of the flowing water and the outside air, and furthermore, stagnation and freezing of the flowing snow water at the flux outlet occur due to a decrease in the snow melting ability of the flowing water. However, from the perspective of securing local roads, snow removal using such snow ditches is attracting attention, and even in the extremely cold region of Hokkaido, snow ditches are being installed, and the problems mentioned above are being solved. Various measures have been taken to resolve this issue.
これらの対策としては、
■ 投雪口部の前後の２〜３ｍの間の、雪塊落下により
飛散する飛沫の凍結による着氷を防止する為の冷気進入
防止対策。These measures include: - Measures to prevent cold air from entering between 2 to 3 meters before and after the snow throwing opening to prevent ice formation due to freezing of droplets scattered by falling snow masses.
■ 流雪溝部の曲部および合流部等における流水の乱流
によって生じる凍結防止の為の冷気進入防止並びに構造
上の対策。■ Structural measures and prevention of cold air intrusion to prevent freezing caused by turbulent flow of flowing water at curved and merging sections of snow grooves.
■ 投雪口部の遮蔽蓋の凍結固着の開閉を容易にする為
の軽量化および固着防止対策。■ Light weight and anti-stick measures to make it easier to open and close the snow-throwing opening's shielding lid from freezing and sticking.
■ 雪塊の落下による飛散を減少させる為の、投入雪塊
の堆積を小さくする格子枠対策。■ In order to reduce the scattering caused by falling snowflakes, measures are taken to reduce the amount of piled-up snowflakes.

各種材質が用いられている。In any case, in extremely cold regions like Hokkaido, it is impossible to avoid the problem of freezing and freezing, and there are currently no materials that can completely prevent icing, so materials that can easily peel off icing are recommended. It is desired to develop a so-called anti-icing material, and efforts are being devoted exclusively to its development. As a method implemented under such circumstances, a method of applying paint or adhering a metal plate to the surface of the inner wall of the snow throwing spout is known. Specifically, examples of the former type of paint include, for example, a silicone-based organopolysiloxane resin called Diff Port S, a mixture of cement and acrylic urethane resin called Cementex, a specially modified acrylic silicone-based resin called Non-Stick, and NTP. unsaturated polyester resin called Mizeron, polyurethane resin called Mizelon, fluorine-modified acrylic resin called NTF, FR
P rubber or the like is used, and various materials are used for the latter metal plate.

っている。(Problem to be Solved by the Invention) The application of the various paints and adhesion of the metal plates described above weakens the adhesion between the surface of the inner wall of the snow-throwing opening and the frozen solids that have formed on this surface. Although it becomes easier to remove frozen solids, there is still one problem as described below from the viewpoint of peelability and durability of these frozen solids.

分とはいえないという問題点がある。In other words, a method in which paint is applied to the inner wall of the snow dumping opening, or to the ceiling wall or side wall of the snow-driving groove near the boundary between the snow throwing opening and the snow-driving groove, has excellent workability and economical efficiency. When poking ice that has landed on water with a stick, it may cause damage to the coating surface of the paint on the inner wall of the snow throwing opening, which poses a problem in terms of durability. There is a problem in that the releasability from the body is not necessarily sufficient.

を決定することが望ましい。By the way, the deeper the snow groove is buried underground, the higher and more stable the temperature inside the snow groove becomes.The deeper the snow groove is buried, the more effectively ice formation on the surface of each wall can be prevented. However, the snow ditches are buried at a depth that takes into consideration the economic efficiency of construction costs. Therefore, at the depth at which the snow drifting groove is buried, it is not possible to expect a heat retention effect inside the snow drifting groove due to geothermal heat, and a drop in temperature of the inner wall of the snow drifting groove cannot be avoided. In any case, it is desirable to decide on the structure, etc. of a snow drift ditch based on a comprehensive evaluation that takes into consideration workability, durability, and economic efficiency.
従って、本発明は前記施工性、耐久性、経済性の総合評

Therefore, the main means adopted by the first invention is a culvert that has a large number of snow throwing ports that open toward the ground, and that allows the snow thrown in from the upper opening of the snow throwing ports to melt and flow with running water. In a snow-drifting groove having a snow-driving groove part of the formula, the inner wall of the snow-throwing mouth part of the snow-drifting groove is covered with a composite plate formed by laminating a foamed metal plate having a large number of closed cells and a metal plate. It is characterized by:

4) is formed integrally by solidifying the snow, and as shown in Figure 1, it consists of a snow dumping opening (2) that opens above ground and a culvert-type snow drifting groove (4) that is buried underground. It was embedded and fixed in the internal concrete wall (3) of the snow throwing opening (2) of the groove (1) with the titanium plate 02) side facing outward. In addition,
When burying the composite plate (0Ω), it is desirable to apply Alboras #250 to the surface of the Alboras plate (IO) on the concrete side to prevent alkaline corrosion of the Alboras plate (II).

着水した氷結体（８）である。Next, the upper part of the opening of the snow throwing spout (2) was configured to be closed with a grating lid (9) that can be opened and closed to prevent atmospheric air from flowing in (in the direction of the downward arrow). In addition, in Figure 1, flowing water (6) is flowing at the bottom of the snow drifting groove (1), and what is floating in this flowing water (6) is water thrown from the snow dumping opening (2). Also, the internal concrete wall (3) of the snow-throwing opening (2) and the ceiling wall (5) near the boundary between the snow-throwing opening (2) and the snow-drifting groove (4). The deposits on the surface of the surface are ice particles (8) that landed on water due to droplets of running water (6) that were scattered in the direction of the upward arrow by the introduction of the snowpack (7).

しても凍結したりすることが少なくなる。Hereinafter, to explain the working mode of the snow drifting groove (1) having the above structure, the thermal conductivity of the Alboras plate (11) is 2.2Kca.
1/mh'C, and because the thermal conductivity is extremely low, a large temperature difference occurs between the temperature underground and the temperature of the air in the snow groove. In other words, since the inside of the snow drifting groove section (4) is maintained at a high temperature, the frequency of reaching freezing temperature is reduced, and the droplets of running water and snow that are scattered when the snowpack (7) is thrown into the running water (6) are kept at a high temperature. Even if the powder adheres to the surface of the titanium plate 0 of the composite plate θ0) disposed on the inner wall of the snow throwing mouth part (2) of the drifting snow if+¥(1), it is less likely to freeze.
