摘要（英）：

The utility model relates to a leak-proof gas injection blind plate for a smudge discharge pipeline, and belongs to the technical field of dredging engineering. The leak-proof gas injection blind plate for the smudge discharge pipeline is characterized by comprising a blind plate body, a gas injection pipe and an inner V-shaped lip rubber washer, wherein the gas injection pipe is installed on the blind plate body, and the inner V-shaped lip rubber washer is installed on a flange. The leak-proof gas injection blind plate for the smudge discharge pipeline has the advantages of being simple in structure, convenient to operate, low in cost, affordable, high in construction efficiency, high in impermeability and the like, thereby realizing leakproofness in the gas injection process of the smudge discharge pipeline, preventing leakage, and guaranteeing smooth construction of the smudge discharge pipeline.
