A road structure for making drainage easy is provided to drain off a large quantity of rainwater smoothly and to protect a pump by discharging rainwater compulsively by operating a pump only using a floater and a clutch if it rains heavily. The road structure for making drainage easy comprises a collecting well(10) buried around a road(12) to collect rainwater, a rainwater discharge pipe(20) connected to the collecting well to discharge the collected rainwater, a housing(32) provided with an opening(34) and inserted to the road, a housing(30) attached to the housing to be reciprocable and provided with a rack gear(31) extended downward, a spring(40) connected to the lower part of the reciprocating block to ascend and to pressurize the reciprocating block, a pinion gear(50) engaged with the rack gear, a driving shaft(60) connected to the pinion gear by a ratchet and rotated forward when the rack gear descends only, a rotation limit device(70) coupled to the driving shaft to limit the driving shaft to rotate forward only, a power storage device(80) composed of a cylindrical housing(81), a spring(82) installed in the housing and connected to the driving shaft and a rotary shaft(83) coupled to the housing and rotated together with the housing, a clutch device(120) connected to the rotary shaft and provided with an output shaft to limit the connection of the rotary shaft and the output shaft, a floater(130) composed of a movable arm attached to the inside of the collecting well to be movable and reciprocable and connected to the clutch device to operate the clutch device according to a reciprocating motion and a floating body placed on the front of the movable arm, a transmission(90) connected to the output shaft of the clutch device, and a pump(100) connected to the output shaft of the transmission and installed in the collecting well to discharge the rainwater collected in the collecting well to the rainwater discharge pipe compulsively. |
