Rainwater drainage assembly and a method for improving a drainage capacity for draining away rainwater from a road.

摘要

A rainwater drainage assembly is provided comprising a channel kerb with at least one inner channel to be positioned on top of a base kerb. A gutter element is provided to be positioned to a front side face of the channel kerb. Rainwater is discharged in a staged manner. In a first stage, the rainwater is infiltrated into the underground by the pervious gutter elements. In a second stage, the rainwater is quickly charged away through passageways formed by the inner channels. In a third stage, the rainwater is infiltrated via a pervious base kerb into the underground. The staged manner of discharging rainwater contributes to an optimal working of the rainwater drainage assembly in providing a fast discharge and at the same time preventing clogging. The rainwater drainage assembly is beneficial to increase a drainage capacity of an existing residential streets.
