As shown in FIG. 1 and FIG. 2, the waterway protection member 1 includes a plurality of vertical frame bodies 2 that are spaced apart from each other in a state of standing upright along a vertical plane, and are vertically spaced and horizontally arranged. It is provided with a plurality of horizontal frame bodies 3 arranged.

The vertical frame body 2 and the horizontal frame body 3 are configured by, for example, joining both ends of a rod-shaped body such as a reinforcing bar in a ring shape, and the horizontal frame body 3 is inserted so as to support the vertical frame body 2 from the inside. The vertical frame bodies 2 are connected to each other by being fixed by welding or the like. The vertical frame body 2 and the horizontal frame body 3 do not necessarily have to be annular, and both ends of the rod-shaped body may be divided.

In the lower portion of the vertical frame body 2, a U-shaped portion 2a is formed which is bent so that both sides of the horizontal portion are vertically erected and is turned 90 degrees to have a U-shape. On the upper portion of the vertical frame body 2, a semicircular arc-shaped portion 2b that is curved so as to project upward is formed. Although the U-shaped portion 2a and the arc-shaped portion 2b of the present embodiment are formed by the same vertical frame body 2, they may be formed by separate members.

Inside the plurality of vertical frame bodies 2, a plurality of horizontally extending reinforcing horizontal members 4 are arranged. In addition, a reinforcing vertical member 5 curved along a vertical plane so as to cover the horizontal frame member 3 and the reinforcing horizontal member 4 arranged on the upper side between the vertical frame members 2 adjacent in the horizontal direction. Multiple are arranged. The reinforcing horizontal member 4 and the reinforcing vertical member 5 can also be formed of a rod-shaped body such as a reinforcing bar, and are fixed to the vertical frame body 2, the horizontal frame body 3, etc. by welding or the like. The reinforcing horizontal members 4 and the reinforcing vertical members 5 may be arranged in an appropriate number according to the interval, size, shape, etc. of the adjacent vertical frame members 2, and when the interval between the adjacent vertical frame members 2 is small, If the vertical frame body 2 itself is small, the reinforcing horizontal member 4 and the reinforcing vertical member 5 may not be provided.

As shown in FIG. 3, the waterway protection member 1 having the above-described configuration can be used for waterways 10 such as gutters and drainage grooves formed on the ground G, and the U-shape of the plurality of vertical frame bodies 2 can be used. The portion 2a serves as a housed portion that is housed in the water channel 10, and the arcuate portions 2b of the plurality of vertical frame bodies 2 serve as a covering portion that projects from the water channel 10 and covers the water channel 10 from above. In this way, since the waterway protection member 1 of the present embodiment only needs to store the accommodated portion in the waterway 10, the construction work can be performed quickly and easily.

The accommodated portion including the U-shaped portion 2a is firmly fixed in the water channel 10 by closely contacting the pair of side walls 11 and 12 and the bottom wall 13 of the water channel 10, and the water channel 10 is reinforced from the inside. Can be protected. Further, by the action of the horizontal frame body 3 that supports each vertical frame body 2 from the inside, the adhesion with the pair of side walls 11 and 12 can be further enhanced. Like the U-shaped portion 2a of this embodiment, it is preferable that the accommodated portion substantially entirely adhere to the pair of side walls 11 and 12 and the bottom wall 13, but at least a part of the accommodated portion includes the pair of side walls 11 and 12. Other shapes that are in close contact with the bottom wall 13 may be used.
