The invention discloses a water conservancy and hydropower construction cofferdam reinforcing device and method, and relates to the technical field of water conservancy construction.The water conservancy and hydropower construction cofferdam reinforcing device comprises a cofferdam attaching arm, an installation fixing arm, a cofferdam reinforcing mechanism and a cofferdam protection mechanism. When the cofferdam is inclined, the pressing air bag which is located on the inner side of the arc-shaped buffer arm on the upper side and attached to the cofferdam is extruded, at the moment, the pigment mixed solution in the pressing air bag is extruded into the prompting hose, and when water conservancy constructors observe that the pigment mixed solution appears in the prompting hose, it is indicated that the cofferdam is inclined; and if the inclination degree of the cofferdam is large, the two ends of the arc-shaped buffer arm located on the lower side extend outwards after the arc-shaped buffer arm is subjected
