The invention discloses a construction method of a reinforcing structure of an overlying construction waste field on soft soil, and provides feasible construction method support for effective implementation of the reinforcing structure of an overlying construction waste foundation on the soft soil. The method includes the following steps that (1) reinforcing pile position plane positioning is performed; (2) column hammer perforating construction is performed on the foundation by the aid of a column hammer machine, and a column hammer performs punching to the soft soil layer surface; (3) vertical reinforcing steel bars are hammered into the soft soil layer around a column hammer hole at intervals; (4) a concrete mixture is mixed, and the placing time of the concrete mixture is shorter thanthe initial setting time; (5) a long and deep jute bag with the open upper part and the closed lower part is placed in the column hammer hole from the ground; (6) the concrete mixture is placed into the long and deep jute bag
