The utility model relates to a cofferdam water retaining structure for mudflat bridge foundation construction, which comprises a water retaining cofferdam comprising a ground water retaining section and an underground insertion section; the soil retaining cofferdam is arranged in the water retaining cofferdam and comprises a ground soil retaining section and an underground soil retaining section, and a mounting space is formed between the ground soil retaining section and the ground water retaining section; and the interlayer platform is arranged in the mounting space. The interlayer platform is used as an internal support of the water retaining cofferdam, the interlayer platform and the water retaining cofferdam jointly resist the water head pressure at the high water level, and meanwhile the interlayer platform is used as a ground foundation and a mechanical operation platform during soil retaining cofferdam construction; therefore, the interlayer platform is used as a mechanical construction channel, the b
