Mixed type connecting structure between tubular pile and bent cap and construction method of mixed type connecting structure

The invention relates to a mixed type connecting structure between a tubular pile and a bent cap and a construction method of the mixed type connecting structure. The structure comprises the tubular pile (1) and the bent cap (2) which are connected in a mortise and tenon mode. A plurality of grouting corrugated pipes (7) are arranged in the cover beam (2), the pipe pile (1) is filled with a core filling section (3), and core filling section longitudinal bars (32) are arranged in the grouting corrugated pipes (7) and the core filling section (3) in a penetrating mode. Compared with the prior art, aiming at the special pier column structure of the prestressed pipe pile, a mixed type connection mode is provided between the pipe pile and the cover beam, grouting corrugated pipe connection and mortise and tenon joint connection play a role together, compared with grouting corrugated pipe connection, the requirement for the lap joint length between the grouting corrugated pipe and the reinforcing steel bars can be
