【Example】

 Next, this invention will be described with reference to the drawings. FIG. 1 is a schematic view of a drainage channel member according to the present invention, and FIG. 2 is a view showing a state in which a heat pipe is mounted. In the figure, reference numeral 5 indicates the main body of the drainage channel member. The main body 5 is composed of a flat plate-like bottom portion 6 and a pair of side portions 7 and 8 which stand substantially vertically from both ends thereof and are opposed to each other. Has been. A plurality of the main bodies 5 are connected to the shoulders of a road (not shown) or the like and installed to form a drainage passage through which heat source water (not shown) such as hot spring water or domestic wastewater flows.

The side portion 7 is divided into an upper portion 10 and a lower portion 11 above and below by a separating line 9 extending in the longitudinal direction below. In other words, the separation line 9 is formed by joining the edge 12 of the upper part 10 and the edge 13 of the lower part 11.

Steps 14 and 15 are formed in the thickness direction of the edges 12 and 13 of the upper portion 10 and the lower portion 11, respectively, and the step portions 14 and 15 mesh with each other to form the upper portion 10 and the upper portion 10. The lower part 11 is connected as expected. A heat pipe attachment portion 16 is formed on the edge portion 13 of the lower portion 11. That is, the edge portion 13 of the lower portion 11 is notched so as to have a width and depth larger than the outer diameter of the heat pipe to be attached thereto, and this notch portion extends over the entire edge portion 13 in the thickness direction. The heat pipe mounting portion 16 is a concave portion formed in this manner. Here, when the upper portion 10 and the lower portion 11 are connected to each other, they are formed to have a rectangular opening. Three such heat pipe mounting portions 16 are provided for each main body 5.

On the other hand, a support member 17 is attached to the upper portion 10. When the upper part 10 and the lower part 11 are connected to each other, this assists the upper part 10 which is slightly unstable until the later-described mortar placing step is performed, and the plurality of heat pipes 18 are connected to the bottom part 6 of the main body 5. It has a function to temporarily fix in a good condition. The shape is preferably such that it does not hinder the flow of the heat source water or accumulate dust. As an example, it is made of wire here, and extends in a line connecting the upper ends of both side parts 7 and 8, and is in contact with the inner wall surface of the side part 8 and bent at the height of the separation line 9 Is formed in

Next, the operation of the present invention configured as described above will be described. In assembling the heat pipe 18 to the main body 5, first, the upper portion 10 and the lower portion 11 are separated. After inserting one heat pipe 18 of corrugated type into each heat pipe mounting portion 16 formed in the lower portion 11, bend the tip end side thereof into a desired shape and lay it in parallel with the bottom portion 6 of the main body 5. . After that, the upper part 10 and the lower part 11 are vertically connected. At that time, since the supporting member 17 presses and fixes each heat pipe 18 to the bottom portion 6, the other heat pipes 18 are also separated according to the one positioned lowest among the heat pipes 18. It is temporarily stopped without kicking. Then, a coagulant such as mortar 19 is placed above the heat pipe 18 and in the gap between the heat pipe mounting portions 16. Since each heat pipe 18 is fixed to the bottom portion 6 in an aligned state, the amount of the mortar 19 to be placed on the upper portion may be small, so that the heat transfer loss from the heat source water to the heat pipe 18 is small, and as a result, Even if the temperature of the heat source water is low, snow melting on the road surface can be performed. With the above procedure, the heat pipe 18 is assembled from the side of the main body 5 toward the inside.

As described above, the heat pipe can be quickly attached to the drainage channel member without using a tool or the like. Even if the heat pipe is bent in advance, it can be mounted without any inconvenience.

FIG. 3 schematically shows a second embodiment of the present invention. In the above-mentioned embodiment, the main body of the drainage flow path member is U-shaped, but in this second embodiment, it is a closed type with the upper part closed, and it is buried in the ground shallowly.

A step extending in the longitudinal direction of the main body is formed at each of the edge portions 26, 27, 28, 29 of the first member 24 and the second member 25 on the side of the separation lines 22, 23, and the step is formed by engaging the steps with each other. The one member 24 and the second member 25 are configured to be well connected.

A heat pipe attachment portion 16 is formed on an edge portion 26 of the second member 25 on the separation line 22 side. That is, the edge portion 26 is cut out to have a width and depth larger than the outer diameter of the heat pipe to be attached here, and the cutout portion extends over the entire edge portion 26 in the thickness direction. The concave portion thus formed is the heat pipe mounting portion 16.

Therefore, when mounting a heat pipe (not shown) in the second embodiment configured as described above, first the first member 24 and the second member 25 are separated, and then the heat pipe. After mounting the heat pipe on the mounting portion 16 and bending it into a predetermined shape, mortar (not shown) is placed above the heat pipe and in the gap between the heat pipe mounting portion 16. Finally, the first member 24 is connected to the second member 25 in a manner of covering the second member 25, and mortar is put from the outside of the separation lines 22 and 23 to perform a water-stop treatment. Through the above procedure, the heat pipe is attached to the main body 5.

Although the drainage flow path is made of concrete in each of the above embodiments, the idea is not limited to the above embodiment, and the drainage flow path member is, for example, a metal pipe having a circular cross section. May also be effective as well.
