Renovation to pavement has been completed. Then, the rainwater on the roadway is quickly drained from the overtaking lane 11 which is a draining pavement, across the second traveling lane 12 and the first traveling lane 13 which are dense-grained pavements, toward the street 22 on the side of the escape lane 14. In order to eliminate this, a first drainage channel gutter 15 is installed.
[0021]
As shown in FIG. 2, the first drainage culvert 15 of this embodiment includes a drainage groove 17 that is open-cut on the pavement surface 16, and a perforated pipe disposed inside the drainage groove 17 along the drainage groove 17. 18 and a water-permeable resin mortar 19 formed by mixing aggregate and epoxy resin, covering and filling at least the upper half of the porous tube 18 in the drainage groove 17. Further, according to the present embodiment, a water-impervious cradle 21 having a concave portion 20 having an arcuate cross section on the upper surface is installed at the bottom of the drainage groove 17, and the porous tube 18 is formed in the concave portion 20 of the water-impervious cradle 21. It is arranged so that its lower part is closely attached along.
