The utility model discloses a water leakage prevention structure for a deformation joint. The water leakage prevention structure comprises a reverse ridge assembly, a waterproof assembly, a protective cover assembly and an external drainage ditch. The reverse ridge assemblies are arranged on the two sides of the deformation joint to prevent an external water source from flowing into the deformation joint, the waterproof assembly covers the outer sides of the reverse ridge assemblies and the deformation joint to prevent external water flow, moisture or steam and the like from entering the deformation joint, and the protective cover assembly covers the periphery of the waterproof assembly to protect the waterproof assembly. The external drainage ditch is used for draining accumulated water in a gap between the protective cover assembly and the waterproof assembly, so that the problems of water seepage and water leakage caused by insufficient sealing performance of a traditional deformation joint structure are s
