When dust such as empty cans and dead leaves is accumulated, a large force acts downward on the water blocking sheet 16, and when deformation due to wind and vibration is repeated, as shown in the enlarged cross-sectional view of FIG. There is a problem that it is broken and the drainage function cannot be maintained for a long period of time and durability is low.

問題がある。Further, in the above-mentioned conventional technique, since both widthwise end portions of the water blocking sheet 16 are fixed to the lower surfaces 17 and 18 of the facing portions 13 and 14 by the anchor bodies 19 and 20, the water blocking sheet 16 is provided. There is no working space that can take out the dust laterally from the inner space, and the dust in the water blocking sheet 16 must be taken out from above the concrete floor slabs 11 and 12 through the void 15. There is a problem of poor workability.

濡れた状態で放置されやすいという問題がある。As described above, according to this conventional technique, the water that has flowed into the water blocking sheet 16 is drained into a predetermined drainage facility for a long period of time by reducing the effective cross-sectional area due to breakage of the water blocking sheet 16, accumulation of dust, and deformation. Can't be led to. In addition, the water guide device 1 is provided in a narrow and inconspicuous place such as under the bridge girder, and it is practically difficult to replace it frequently. Therefore, the waterproof sheet 16
Even if water is leaking due to damage to the housing, or if water leakage may occur, it may be difficult to maintain and manage due to installation conditions. There is a problem that it is easily left unattended.

Concrete structures such as abutments and floor slabs. Concrete is a mixture of cement, aggregate such as crushed stone with a controlled particle size, sand, and water, which is hardened by a hydration reaction.
Most of the water flowing into the water blocking sheet 16 is rainwater, and when this rainwater adheres to the surface of the concrete, the concrete surface gradually loses alkalinity due to the action of carbon dioxide gas in the rainwater, resulting in a hydrogen ion concentration pH. However, the concrete becomes brittle and its strength decreases. Especially in winter, the road surface is sprayed with an antifreezing agent containing chloride to prevent the road from freezing, and the water in which this antifreezing agent is dissolved is removed from the cracks caused by external forces such as drying and shrinkage on the concrete surface. It penetrates into the concrete and corrodes the reinforcing bars. Reinforcing bar expands due to corrosion, develops the crack, and water invades the expanded crack, causing corrosion of the reinforcing bar further, freezing and expanding, causing the problem of stripping concrete .

長期にわたって高い排水性を維持することができる。According to the present invention, the gutter is connected to either one of the facing portions of the two adjacent structures facing each other, and the water guiding auxiliary member is connected to the other of the facing portions. It Since the gutter body has an opening facing upward, the gutter body can receive and collect the water that flows down in the gap between the facing portions, and the water guiding auxiliary member guides the water that flows down in the gap into the gutter body. Therefore, even if relative displacement occurs between the facing parts due to an earthquake or the like, a large external force does not act on the gutter body and the water guide auxiliary member, preventing damage to the gutter body and the water guide auxiliary member. It is possible to reliably collect the water that flows off between the opposing portions. In addition, since the gutter body and the water guide auxiliary member are individually provided at each of the facing portions, a space can be easily formed between the gutter body and the water guide auxiliary member. Cleaning and maintenance can be performed, which reliably prevents water leakage due to dust clogging,
High drainage can be maintained over a long period of time.
