By installing the water blocking plates 1 in the engaging grooves 8 formed on both the left and right sides of the water channel so that the rubber or soft resin packings 2 attached to the upper and lower ends of one side are located on the downstream side. The rubber or soft resin packing 3 at the lower end is pressed by the weight of the water blocking plate, and the side packing is pressed by the water pressure on the upstream side to prevent water leakage.

When the water stop plate 1 is removed, by rotating and opening the upstream plug 4a of the water reducing plug 4, the snow melting water on the upstream side flows into the downstream side and there is no drop in the water level. Since the water pressure difference at is eliminated, it can be easily removed.

When the material of the water stop plate is synthetic wood,
As the specific gravity is lighter than water, it rises. In order to prevent this, on one side or both sides of the upper surface of the water blocking plate 1, a quarter circular arc-shaped serrated portion 5a rounded toward the bottom so that the blade-shaped plate-shaped tip does not slip easily is formed. Attach a metal or synthetic resin uplifting prevention member 5 which is formed and locked at the other end with a pin or the like so as to be rotatable, and rotates the prevention member to push it into the engagement groove 8 wall of the side wall from above. By the wedge action by the above, the rubber or soft resin packing at the lower end portion of the water blocking plate is pressed downward to prevent water leakage, and also the floating of the water blocking plate can be prevented.

By providing Z-shaped storage jigs 7 and 7a made of metal or synthetic resin on one side of the water channel,
Since the water stop plate 1 can be stored in the water channel as it is at times other than winter, maintenance is easy and economical.
