往往使绿地略高于路面,当两侧绿地径流汇于道路之后,雨水可以沿路网纵向坡

The green space is often slightly higher than the road surface. When the green land on both sides converges on the road, rainwater can drain along the longitudinal slope of the road network. Some road networks need to be provided with a drainage ditch or an open ditch on the side of the road. Generally speaking, only a wide garden road has the conditions for setting a drainage ditch, which is generally the main garden road in the park. The rainwater is drained into the road network ditch through the cross slope of the road surface, and drained into the urban drainage pipeline or nearby natural water system through the pipeline. The rainwater collection port can be decorated with ornamental materials.

Green space is often slightly higher than the road surface, when the green space runoff on both sides of the road, rainwater can be drained along the vertical slope of the road network. There are also road network design needs to set up drainage ditches or ming ditches on one side of the road, generally speaking, only a wider garden road has the conditions for a drainage ditch, generally the main garden road in the park. Rainwater is concentrated in the road mesh ditch through the cross slope of the road surface, and discharged through pipes into urban drainage pipes or nearby natural water systems. Rainwater collection ports can be decorated with ornamental materials.
