[Function] Has a constant width and thickness only in the vertical direction at both ends on the downstream side of the plate-like member formed of a metallic material, a synthetic resin material, a synthetic wood or a composite member thereof, and only in the entire width of the lower end. By attaching the packing made of rubber or soft resin, a more effective joint seal state is formed by the packings attached to both ends on the downstream side of the plate member made of a material preferable as the water stop plate for the snow melting groove.

Further, since the movable stopper is provided on the upstream side of the water channel at the lower end side of the plate-like body, the water level formed by the plate-like body is controlled by appropriately operating the movable stopper. Adjust accordingly.

By using a plate-shaped member formed of synthetic wood as a main material, a plate-shaped member that is lightweight and easy to handle can be obtained, and one or both of the upper parts of such a plate-shaped member can be obtained. By attaching a rotary preventive tool having multi-step engagement teeth for preventing lifting due to buoyancy, the lifting of the plate-shaped body can be easily and accurately prevented by a wedge action due to rotational pushing of the preventive tool.

A jig for storing metal or synthetic resin is attached to the inside of one side of the water channel, and a water blocking plate to be attached to and detached from the water channel is attached to the inside of the one side of the water channel so that it can be stored. As a result, the above-mentioned water stop plate is stored in the water channel itself, that is, special equipment for storing the water stop plate as in the past and the arrangement and transportation of the removed water stop plate are completely required. It is possible to store the snowmelt groove device using the water blocking plate immediately at each site while storing it.
