The invention discloses a spliced water drainage pipeline. The spliced water drainage pipeline comprises a pipeline body composed of one or more spliced pipes. Each spliced pipe is of a cylindrical hollow structure, a water drainage channel is arranged in the middle of each spliced pipe, every two adjacent spliced pipes are arranged in a direct butt-joint manner, and each of the butt joint faces of the spliced pipes is provided with a sealing ring. Each of the two sides, right opposite to the spliced pipes, of the sealing rings is provided with an annular cavity. The opening ends in the two ends of each spliced pipe are arranged in the corresponding annular cavities in a sealed manner. The middle of each sealing ring is provided with one or more through holes around the sealing ring by onecircle. An elastic rubber pipe penetrates through each through hole. The spliced water drainage pipeline is formed by splicing one or more spliced pipes, a circle of elastic rubber pipes are arrangedinside in a seal manner, and therefore during shearing, the two spliced pipes at the adjacent ends can be separated, the inner elastic rubber pipes are stretched, shearing is resisted, and very goodanti-shearing capability is achieved; and meanwhile, the inner elastic rubber pipes can be used for explosion preventing and buffering, and the pipeline using safety is greatly improved.
