Moreover, it has the effect that the rainwater which arose in the level | step-difference part which contacted with the side groove | channel block produced by the depression of a road, the wear of asphalt material, etc. can be efficiently and rapidly led into a side groove | channel.

  However, since this conventional water conveyance member is attached to the side wall of the side groove block, it can only deal with underground water flowing from the road on the side where the water conveyance member is attached. In general, a water guide member is attached only to the roadway side, and only underground water coming from the permeable pavement laid on the roadway side is introduced.

However, underground water flowing from the side opposite to the roadway side must be introduced into the gutter block as well. For example, in the case of underground water that flows from the sidewalk when there is a sidewalk on the side of the roadway, or in the case of a gutter block that is provided on a mountain road, rainwater that exudes from the slope of the mountain as well as the roadside It is necessary to correspond to. In such a case, in the conventional water-conducting member, the water-conducting member has to be attached to the side walls at both ends, and the manufacturing process is increased and the cost is high.
