The present invention will be described below based on the drawings of the embodiments.
For example, FIG. 1 shows an entire baseball stadium. Generally, 50 cm of a base crushed stone is laid, and 10 cm of gravel and 10 cm of volcanic gravel are laid on top of each to form a base layer. The entire baseball stadium Z is composed of about 30 cm of surface layer mixed with sand.

Subsequently, the first zone Y, which is a diamond region, a so-called infield region, exposes the surface layer obtained by mixing black soil and sand as it is, and the second zone X, which is the outer field region, is a surface layer obtained by mixing the black soil and sand. The natural turf W is laid on the ground.
Furthermore, for the laying of the artificial turf W, 50 cm of cracked stone, 10 cm of gravel above it, and 10 cm of volcanic gravel are spread as appropriate. Covered.

A predetermined number of U-shaped drainage grooves 1 having a certain length (about 1 m) are connected directly below the boundary line L between the first zone Y and the second zone X to connect the entire boundary line L between the zones X and Y. Buried over the circumference.
Of course, the first end of the U-shaped drainage groove body 1 is stopped by a water stop plate, and the final end reaches from a rainwater mass (not shown) to a public sewer pipe.

Subsequently, the intermediate frame 2 is seated on the U-shaped drainage groove body 1 to close the upper end opening 1 a, and the intermediate frame 2 is also seated on each U-shaped drainage groove body 1.
The top plate 2a of the intermediate frame 2 is composed of a small rising left and right side plate 3 forming a rainwater inflow channel R, and a grating block with a metal left and right grating elongate material 4 having the same length as the rising left and right side plate 3 Rainwater near the boundary line L between the first zone Y composed mainly of sand and the second zone X composed of natural / artificial turf without forming a U-shaped drainage groove Drain quickly at
The metal left and right grating elongate material 4 is preferably made of stainless steel in view of its specification, but of course, other metal may be used.

  In this state, it is undeniable that a slight lateral deviation occurs in the intermediate frame 2 with the U-shaped drainage grooves 1 connected in a plurality, and in particular, the first zone which is a diamond region, a so-called infield region. Since the boundary line L between Y and the second zone X, which is the outer field area, has an arc shape, a straight metal left and right grating elongate material 4 as shown in FIG. In other words, there is an adjustment gap t for forming an arc shape between adjacent ones.

  Because of this unstable connection state, a connecting piece 5 having a base end 5a fixed by welding or the like is provided on the outer side surface of each of the left and right grating elongate members 4, and the other connecting the tip 5b. The left and right grating elongate members 4 are inserted into and connected to each other, and the left and right grating elongate members 4 are placed on the left and right side plates 3 of the predetermined intermediate frame 2 so that the U-shaped drainage grooves 1 are connected to each other. Until then, the connecting pieces perform the adjusting function so that the linear grating blocks can be connected to each other in a proper arc shape with a predetermined length.

Thus, together with the U-shaped drainage grooves 1 connected to each other, even if a slight lateral deviation occurs in the intermediate frame 3, it is corrected by the connecting piece 5, and the first zone Y and the second zone Corresponds to the arcuate boundary L with X.
When the intermediate frame 2 is made of metal, the left and right grating elongate material 4 and the intermediate frame 2 are welded together, so that they are more robust and properly connected.
The intermediate frame 2 may be made of a synthetic resin, and the right and left side plates 3 of the intermediate frame 2 may be coupled to the left and right grating elongate members 4 of the metal grating block B, and is not particularly limited.

  The U-shaped drainage groove body 1 and the left and right grating elongate material 4 are laid at a predetermined position on the boundary line L between the first zone Y and the second zone X serving as the outfield region, and then the left and right grating elongate material 4 is rubberized. A U-shaped linear covering cap 6 such as a synthetic resin is attached to reduce the risk of the metal left and right grating elongate material being directly exposed and caught on the player's shoes.
