The invention discloses a steel caisson pile structure used for a steep reservoir bank slope and a construction method. A plurality of construction platforms (2) are divided into two groups, one groupof construction platforms (2) is arranged on the shore side, and the other group of construction platforms (2) is arranged on the water side; the construction platforms (2) on the shore side are located above the dead water level (8) and provided with cranes (7); the construction platforms (2) on the water side are located below the dead water level (8) and provided with steel casings (3) and steel caissons (4). The defects that in the background technology, when a reservoir bank slope is steep, a positioning barge cannot be pulled in to the shore for caisson pile foundation construction andin-box pile foundation construction are overcome, and the steel caisson pile structure has the advantages that water pollution caused by cofferdam filling, occupation of the capacity of a reservoir and construction of an anti-
