A tower crane foundation bolt fixing method is characterized by including the following steps that firstly, a tower crane supporting leg fixing frame (9) is manufactured by machining steel materials of the same specification as those of tower crane standard knots; secondly, bottom supporting stirrup parts (5) of tower crane supporting legs are formed by reinforcing steel bars with the diameter of 25 mm according to the measured size of the bottoms of the tower crane supporting legs; thirdly, measurement and setting out are conducted on a foundation cushion layer where concrete pouring is completed, line-snapping setting out is conducted on the installation positions of the tower crane supporting legs, the manufactured tower crane supporting stirrup parts (5) are placed in the positions subjected to setting out, and adjustment is conducted through a level gauge; fourthly, the four tower crane supporting legs (4) and the supporting leg fixing frame are assembled through high-strength bolts (8) together in advance; fifthly, a reinforcing steel bar reinforcing frame is arranged on the lower portions of the supporting legs to ensure that no displacement happens in the concrete pouring process of the bottoms of the supporting legs. The method has the advantages that the tower crane foundation bolt embedment installation accuracy is high, the construction process is easy and convenient, the subsequent standard knot installation is smooth, the construction cost is low, and the installation effect is good.
