Fig. 1 to 4 show a novel drainage structure for a bridge deck 2, which comprises a bridge pillar 1 and a bridge deck 2 disposed on the bridge pillar 1, and protective baffles 3 are disposed on two sides of the bridge deck 2. 2 both sides of bridge floor are equipped with the water drainage tank 5 of getting rid of ponding on the bridge floor 2, can dismantle on the water drainage tank 5 and connect a drainage cover plate 4, be equipped with the filtration pore on the drainage cover plate 4, can avoid the impurity of great granule to fall into water drainage tank 5.

5 bottoms of water drainage tank are equipped with a wedge bottom plate 21, and this wedge bottom plate 21 can slide from top to bottom along water drainage tank 5, for the upper and lower activity that realizes wedge bottom plate 21, carries out following setting:

a driving block 6 matched with the wedge-shaped bottom plate 21 is arranged below the wedge-shaped bottom plate 21, the driving block 6 is arranged in a sliding groove 7 on the bridge deck 2 body, and the wedge-shaped bottom plate 21 can be driven to slide up and down through the change of the position of the driving block 6. It should be noted that the distance from the wedge-shaped bottom plate 21 to the opening of the drainage channel 5 is L1, the height of the driving block 6 is L2, and L1 is L2. Thus, when the driving block 6 acts, the upper surface of the wedge-shaped bottom plate 21 is flush with the bridge deck 2, and cleaning can be conveniently carried out.

The driving block 6 includes a rotating motor 8, a working chamber 9, a driving screw 10, and an ear plate 11 disposed below the driving block 6. The operation bin 9 is arranged below the sliding groove 7, the driving screw 10 is arranged in the operation bin 9, one end of the driving screw is rotatably connected with the side wall of the operation bin 9, the other end of the driving screw is connected with an output shaft of the rotating motor 8, and the rotating motor 8 is arranged in a cavity inside the supporting beam.
