な金具（図示せず）で連結する。As shown in FIG. 5, the elastic plate 30 includes a large number of elastic particles 34, such as rubber chips or cork chips, which are bonded to each other at intervals to form a layered structure, and which are embedded in the large number of elastic particles 34. reinforcing member 36, preferably made of metal
It consists of In order to obtain good adhesion between the elastic plate 3o and the coating 32, the adhesive for the elastic granules 34 is preferably the same as the constituent material of the coating 32, and in the illustrated example, urethane resin is preferable. The elastic plate 3o produced in a factory is set to a size that can be accessed, for example, in consideration of transportability from the factory to the site and within the site. The reinforcing member 36 can be arranged so as to be embedded in a large number of layered elastic particles 34 instead of the illustrated example in which the stiffness is arranged on the bottom surface of the elastic plate 30. The plurality of elastic plates 30 that are laid out, that is, the plurality of elastic plates 30 that are arranged side by side with each other, are desirably connected by suitable metal fittings (not shown).

により、盛土２０の露出面からの水の侵入を防止しまた
盛土２０のくずれ落ちを防止することができる。Since the surface layer 16 is sloped along the surface of the support layer 14 and is water-impermeable, rainwater or water used for cleaning the court flows down the surface of the surface layer 16, that is, the court surface, toward the ground. Preferably, a gutter 38 is provided on the outside of the curb 18A to receive and direct runoff water to a predetermined location. In order to prevent the flowing water from flowing into the inside of the curb 18A, as in the illustrated example,
It is desirable that the top surface of the curb 18A be covered by the surface layer 16. Furthermore, preferably, prior to forming the cover i32, a part of the elastic plate 30 along the curb 18A and a part of the outer side surface of the curb 18A (the surface facing the side gutter 38 of the curb 18A) are covered with a band-shaped cloth ( When forming the covering 32, the synthetic resin liquid for forming the M32 is applied to the surface of the cloth so as to be continuous with the covering 32. This can prevent water flowing down the surface layer 16 from entering the embankment 20 and causing the embankment 20 to collapse. In addition, a part of the same band-like cloth as described above was placed along the curb 18B on the elastic plate 30.
The embankment covers a part of the earth, and the remaining part hangs down.
When forming the cover i32,
The synthetic resin liquid for forming the coating is applied to the cloth and applied to the frame 22. ~22. Make it adhere. This can prevent water from entering through the exposed surface of the embankment 20 and prevent the embankment 20 from collapsing.

By changing the hardness, size, etc. of the elastic particles, the cushioning properties can be changed. The reinforcing member 36 increases the bending resistance of the elastic plate 30, that is, the tearing resistance of the layered elastic granules 34 when the impact is applied.

An inclined coat surface can also be obtained by forming a surface layer, specifically an elastic plate, whose thickness gradually decreases from the center line toward each short side of the rectangle.
