In addition, 8 is a water collecting hole provided in the lid portion 3, 9 is an anchor,
J is expansion joint post-cast concrete. Thus, rainwater and the like accumulated on the road surface in the drainage channel formed as a whole are partially collected in the water collection hole 8 of the lid section 3 of the steel drainage channel unit 1 and guided to the water channel section 2, The floor slab water that has passed through the pavement layer H is guided to the water guiding hole 5 that is opened in the side portion 4 of the water channel portion 2 through the water guiding groove G of the road shoulder concrete B, and is discharged after passing through the water guiding pipe connected to the lid 6. Run down the pipe.

Here, the reason why the lid 6 provided on the side portion 4 of the water channel portion 2 of the steel drainage groove unit 1 is covered is that water flowing through the drainage groove does not flow backward, and the water conduit 7 is connected to the lid 6. It is impossible to attach the lid 6 up to the end pipe F to the side part 4 without connecting the water conduit 7 because the connection of each unit is made of rubber waterproof packing and joints because the elastic part bends and expands and contracts. Because there is.
