Bridge drainage leakage-proof structure

The utility model discloses a bridge drainage leakage-proof structure, and relates to the technical field of bridge drainage. The bridge drainage leakage-proof structure comprises a first drainage pipeline and a second drainage pipeline, and sealing leakage-proof structures are arranged on the outer sides of the first drainage pipeline and the second drainage pipeline. When the bridge drainage leakage-proof structure is used, the left shell and the right shell can be accurately paired through cooperation of a guide hole and a guide rod, and through cooperation of a mounting column, a limiting groove, a spring, a fixing cylinder, a rotating block and a screw rod, when a handle rotates, a moving block and a rubber layer can be driven to move, so that the bridge drainage leakage-proof structure is convenient to use. The effect of fixing the left shell and the right shell is achieved, meanwhile, the pressing effect of an annular clamping plate and a clamping shell on a sealing ring is better, and through cooperat
