Municipal road drainage system and drainage method
The invention discloses a municipal road drainage system and a drainage method. One part of rainwater is converged along a road surface to a municipal road gully and then enters a municipal rainwater pipeline; the other part of rainwater flows to a greenbelt between a motor way and a non-motor way through holes in curbs on two sides of the motor way; after the rainwater entering the greenbelt is filtered and purified by the greenbelt to infiltrate downwards, excessive rainwater flows into a permeation tube of a permeation drainage pipeline system to infiltrate downwards for replenishing the underground water, and the rainwater which does not infiltrate downwards quickly due to high rainfall intensity is drained through an overflow pipe of the permeation drainage pipeline system to the municipal rainwater pipeline under the motor way; the rainwater directly entering the municipal rainwater pipeline through the municipal road gully and the rainwater entering the municipal rainwater pipeline through the overflow pipe of the permeation drainage pipeline system are jointly drained to a nearby water body through the municipal rainwater pipeline. According to drainage performances of the greenbelt and the permeation drainage pipeline system, purification of initial contaminated rainwater, deceleration of peak discharge, relief of urban water logging, replenishment of underground water and the like are realized.
