And a water receiving member 60 installed between the pair of the fixing member 50 to block the inflow of gravel or rainwater while receiving the displacement of the upper plate.

The lower end of the water receiving member 60 is formed with a semicircular lower end portion 61 so as to have a tensile force and an upper end portion 62 bent at a predetermined angle so as to have a tensile force also at the upper end portion. A folded portion 63 bent downward to be assembled inside the fixing member 50 is formed.

Therefore, when it comes to rain, the water is drained down through the water tray 60.

However, if rainwater or the like is not adequately discharged from the water receiver 61, the rainwater overflows between the upper wing portion 51 and the upper end portion 62, and the overflowing rainwater is carried by the fixing member 50 and is impregnated into the slab or pier affect.

In order to solve this problem, in Patent Document 3 filed and filed by the applicant of the present invention, a packing is inserted into the lower end of the upper wing portion in order to seal between the lower end and the upper end of the upper wing portion.

The packing 40 is constituted by a groove 41 on the channel end face and a contact portion 43 formed on the bottom face of the groove 41 as shown in Fig.

And the groove 41 is inserted into the lower end of the upper wing portion.

The packing (40) requires maintenance, such as a replacement life due to various reasons.

It is almost impossible to remove the packing 40 to be replaced and install a new packing.

That is, since the interval (3 to 10 cm) between the flow channels is short and the depth is about 1 m, it is impossible to hold the packing 40 and remove it and reinstall it.

In addition, in order to repair the package 40 in the state of being constructed as in Patent Document 1 (or Patent Document 2 of FIG. 8), the packing 40 of Patent Document 3 is inserted into the lower end of the upper wing portion 51 of Patent Document 1 impossible. This is because it is not possible to hold the packing 40 by hand and place the packing 40 to the lower end of the upper wing portion 51, and there is no portion where the packing 40 can be held by another tool.

Therefore, the packing 40 of Patent Document 3 can be applied only when the upper wing portion 51 is a lid for attaching and detaching.

In addition, the packing 40 of Patent Document 3 can be applied only when the upper stover plate 230 of Patent Document 2 is a lid for attaching and detaching.
