溝の上面との間に段差ができない。2. Description of the Related Art There are two types of gutter blocks for constructing relatively narrow waterways, such as U-shaped groove blocks and variable-gradient blocks. U
The U-shaped groove block has a side plate and a bottom plate integrated with each other, and the upper surface is open over the entire length of the block. On the other hand, in the variable gradient block, the side plate and the top plate are integrated, and a rectangular opening is provided in a central portion of the top plate. These blocks form a water channel by being connected in the longitudinal direction. The channel constructed with the variable slope block has a bottom surface formed of cast-in-place concrete, and the channel gradient of the channel bottom can be different from the top plate, that is, the gradient of the ground surface. Therefore, if the side gutter of the road is constructed by the variable gradient blocks, a step cannot be formed between the road surface and the upper surface of the gutter.

付けられている。FIG. 12 is a sectional view of a conventional variable gradient block. The opening 4 on the upper surface of the gutter block has a gutter cover 1
1 is provided. In order to support this gutter cover, a step (cover) 5 is provided on the side of the opening of the gutter block. In the conventional gutter block, the inner surface of the side wall is a vertical surface (mainly in the case of a variable gradient block) or an inclined plane inclined in a direction in which the upper part of the water channel is widened (only in the case of a U-shaped groove block). The lid 5 is formed by cutting the upper side into a shape cut out into an L-shaped cross section.
In response to the cut-out on the inside, an outer flange 17 protruding outside is provided to secure the width W of the upper end of the side wall required for strength. Even if the side wall inner surface is a vertical surface, the draft required to remove the block from the formwork is such that the upper part of the channel becomes wider in the U-shaped groove block, and the lower part of the channel in the variable gradient block. Is attached in the direction of becoming wider.

実用的である。The sectional shape of the side groove block according to claim 1 is
The required channel width P is determined from the maximum amount of water flowing through the side groove, and the side wall thicknesses S 1 and S 2 required to give the side wall the strength to withstand the earth pressure are determined to determine the side groove width. Next, after securing the width W of the upper end of the side wall necessary for strength, the shape of an obtuse angle L-shaped notch for fitting and supporting the side groove lid 11 and the width M of the lid hook 5 are obtained, and the protrusion of the inner flange 6 is determined. After determining the amount, the vertical dimension of the inner flange 6 is determined from the maximum load applied to the gutter lid, and the lower side edges 12 of the lower surface of the inner flange 6 are transferred so that the load acting on the lid hook 5 is smoothly transmitted to the side wall 2. Is determined as an inclined surface. The slope of the lid 5 is 30 to 60 degrees,
It is practical that the radius of curvature when formed into a middle convex cylindrical surface is 30 to 200 mm.

S 2 is the thickness required by the vertical dimension of the block is varied. When the height of the block is high, the earth pressure applied to the side wall increases, and the wall thickness S 1 , S 2
Need to be thicker. In a channel formed by variable slope blocks, the slope of the ground surface and the slope of the channel bottom may be different from each other. Therefore, it is often necessary to construct a channel by connecting blocks having different heights. The widths K 1 and K 2 of the block of the present invention determined as described above are equal to the thicknesses S 1 and S 2 of the side walls, that is, the heights R 1 and R of the blocks when the same channel width is to be ensured. It may be different depending on the change of 2 . In this case, if the structure of claim 2 (or 3) is adopted for the block having a large vertical dimension, the shape of the upper end of the gutter block and the shape of the gutter cover appearing on the ground surface are changed to the heights R 1 , R of the gutter block. They can be the same regardless of the difference between the two .

The width Q of the lid 11 can also be reduced. For this reason, when a road gutter is constructed, the road surface on which vehicles pass is widened, and the probability of tires passing over the gutter cover is reduced, so that noise due to rattling of the gutter cover can be reduced. In addition, since the width and thickness of the gutter block and the gutter lid can be reduced, the amount of concrete required for forming the block is small, and the block can be reduced in weight,
The amount of excavation on the ground surface when constructing gutters is also reduced.

少なくなる。Further, in the gutter block of the present invention, since the vertical portion of the side wall outer surface 9 is the outermost surface in the width direction of the block, it is easy to arrange the blocks in a straight line. . That is, if the piles 16 are erected on the road and the blocks 9 are arranged side by side with the outer faces 9 of the side walls, which are the outer sides of the blocks, the position of the connected blocks in the width direction and the inclination around the longitudinal axis can be easily defined. it can. And since the outer surface 9 of the side wall of the block has no irregularities, the backfill of the earth and sand is easily and reliably performed, and the amount of the earth and sand to be backfilled into the empty space after the sheet pile is removed is small. The groove for filling the block may be excavated by a power shovel along the sheet pile, and the width of the block is small, so that the excavation work is easy and the discharge of earth and sand accompanying the excavation is reduced.

When the side groove cover 11 is slightly rotated around the vertical axis to absorb the error, the lid hook 5 and the lower side edges 1
The contact of the four corners with 2 is completely assured, and the gutter cover does not rattle on the lid hook 5, so that it is possible to prevent the generation of noise when the vehicle passes over the gutter cover.

It is possible. That is, FIG. 8 shows an example in which the lid hook 5 has a shallow inverted V-shaped cross section, and the lower side portions 12 on both sides of the gutter cover have an inclined plane. FIG. This is an example in which a flat surface is formed, and a lower convex side surface of the side groove block is formed as a convexly inclined cylindrical surface. FIG. This is an example of a shallow V-shaped cross section. In any of these combinations, the self-aligning action described in the first embodiment also exerts the gutter cover backlash absorbing action.
