The invention relates to the technical field of tunnel construction, and provides a construction method for transmitting force by using a pipe-jacking reaction frame of an existing station main body structure, which comprises the following steps of: arranging a supporting groove body on one side, deviating from a jacking pipe, of an existing wall body of a pipe-jacking originating well; a plurality of counter-force frames used for supporting a wall body are arranged in the supporting groove body; the jacking pipe is supported on the existing wall body, and jacking pipe construction is operated; and a monitoring device is arranged on the reaction frame and/or the existing wall, whether the reaction frame deforms or not is monitored in real time, if not, pipe jacking construction continues, and if yes, pipe jacking construction is suspended. By means of supporting of the counter-force frame, enough reverse supporting force can be provided for an existing wall and a pipe jacking structure, enough safety and stab
