Construction method for steel pipe support of concrete girder of tied-arch bridge in shallow water area

The invention discloses a construction method for a steel pipe support of a concrete girder of a tied arch bridge in a shallow water area, which comprises the following steps of: completing steel pipe pile inserting and driving construction in the shallow water area close to a shoreside on land through a crane pile driver, building a starting end of an underwater platform at the top of the steel pipe pile, and reserving a through hole for a steel pipe column to pass through in the underwater platform; the crane pile driver lowers the steel pipe column to a riverbed from the underwater platform, then the steel pipe column is inserted into the bottom of the riverbed through a vibration hammer, the operation is repeated, and construction of each segment of the underwater platform and inserting and driving operation of the steel pipe column are completed step by step; and then the underwater platform is disassembled from the tail end of the underwater platform, after each section of the underwater platform is dis
