Prefabricated hollow pier and bearing platform inner tenon connecting structure and construction method

The invention discloses a prefabricated hollow pier and bearing platform inner tenon connecting structure and a construction method. The prefabricated hollow pier and bearing platform inner tenon connecting structure comprises a bearing platform and a prefabricated hollow pier stand column. A round hole is formed in the prefabricated hollow pier stand column, and high-strength toughness concrete is adopted for local reinforcement between the lower end and the bearing platform and between the outer side wall close to the lower end and the bearing platform. The bearing platform is provided with prefabricated inner tenons corresponding to the prefabricated hollow pier stand columns. The prefabricated inner tenon is in a circular truncated cone shape, and the diameter of the upper end and the diameter of the lower end of the prefabricated inner tenon are both 10-15 cm smaller than the inner diameter of the circular hole, so that a pouring crack is formed between the outer side wall and the circular hole; and each
