Description of the Related Art Gutters constructed from concrete U-shaped blocks are drainage gutters for collecting drainage from houses and road surfaces and guiding them to a specified sewage treatment plant. If it is a flat surface, the gutter is also flattened, drainage cannot be formed, sewage collects, gives off a strange odor, and is unsanitary. Such precast concrete gutters are provided (see JP-B-56-51113 and JP-B-57-2551).

In constructing b and 1c, as shown in FIG. 7, for example, a plurality of lower blocks 3 are laid side by side on a horizontal foundation 22 placed in the side-grooving excavation groove so as to have a required length. Forming gutters, the bottom of the lower block 3 is ready for concrete 2
3 is poured into the concrete 23 through the through hole 14.
Is connected to the foundation 22, and the ready-mixed concrete 23 is leveled over the entire length by a leveling tool 24 so as to have a required gradient θ. The leveling tool 24 is one in which a leveling plate 26 that is bent back and forth or a leveling plate 27 that is bent back is attached to one end of a rod 25 having a predetermined length, and the lower block 3 is open upward. It is easy to move the leveling tool 24 because there are no obstacles.
