Road surface drainage device accelerates

The utility model provides a road surface drainage device accelerates, including seal structure's cistern, cistern top intercommunication has an inlet tube that is used for road surface drainage, theexhaust apparatus of air in the export below of inlet tube is equipped with the cistern that is used for discharging. Through the water wheels rotor below the water impact cistern, the water wheels rotor drives piston motion to produce the negative pressure at the cistern, the negative pressure is led to pipe and is produced suction to ramp water -storage layer, and the discharge of ramp infiltration ponding with higher speed so that comparatively fast get rid of the inside rainwater in road surface, prevents that the rainwater from piling up, accelerates the dry progress in road surface. Thissystem energy saving environmental protection does not need the outside to provide the power supply, and the maintenance period is long, and is with low costs, and the commonality is strong, has verywide marketing application
