The material of the double-sided tape is not particularly limited, and for example, a polyester resin, an acrylic resin, a silicon resin, or a butyl resin can be used. Of these, butyl-based and acrylic-based waterproofing materials are desirable.

Next, the drain plug 300 will be described with reference to FIGS. 9 and 10.

Fig.9 (a) is a top view which shows typically an example of the drain plug shown in FIG. 1, FIG.9 (b) is a longitudinal cross-sectional view which shows the use condition.
As shown in FIGS. 9A and 9B, the drain plug 300 includes a frame member 320, a sealing member 330 placed inside the frame member 320, the frame member 320 and the sealing member 330. A drainage sheet 340 sandwiched between the sealing member 330 and the fixing member 350 for fixing the sealing member 330 from above, and a wire mesh 360 sandwiched between the sealing member 330 and the fixing member 350. The drain plug 300 is fitted to a cylindrical body 380 provided on the solid base 201 from above. The cylindrical body 380 is provided on the solid foundation 201 by being disposed at a predetermined position before pouring the ready-mixed concrete in the solid foundation construction process.
In the present embodiment, the frame member 320, the sealing member 330, and the fixing member 350 are made of resin. However, in the present invention, the materials of the frame member, the sealing member, and the fixing member are particularly limited. However, it may be made of resin or metal.

When water accumulates on the solid foundation 201, the water enters the drain plug 300. At this time, when foreign matter such as a stone having a large diameter enters with water, the foreign matter is blocked by the hole of the fixing member 350.

When the water further flows down, it collects on the draining sheet 340 sandwiched between the frame member 320 and the sealing member 330. If it does so, the boundary surface part with the water in the sheet | seat 340 for water draining will be pushed down by the weight of water, and the sheet | seat 340 for water draining will bend below.

The water flows down to the lower side of the water draining sheet 340 through the space generated by the water draining sheet 340 being bent. Thereafter, when there is no water on the boundary surface and no downward pressing force is applied, the water draining sheet 340 is returned to its original state by its elastic force and closed again.

Thus, in the drain plug 300, the valve is formed by the frame member 320, the sealing member 330, and the draining sheet 340 sandwiched between the frame member 320 and the sealing member 330. And when the water collected on the upper surface of the solid foundation 201 flows in, the drainage sheet 340 bends and this water flows down to the lower part, and the water collected on the solid foundation 201 can be discharged.

FIG. 10 is a perspective view showing a lid detachable from the drain plug.
The sealing plug 370 has a dish shape having a recess 371 having a size corresponding to the outer periphery of the frame member 320, and a handle 372 is formed on the outer periphery. The sealing plug 370 can be attached and detached from the upper side of the frame member 320.
