Settlement joint structure formed by single pouring and construction method

The invention discloses a settlement joint structure formed through one-time pouring and a construction method. The settlement joint structure comprises a first embedded part and a second embedded part which are arranged on the two opposite sides of a settlement joint. The sliding sticking part is arranged between the first embedded part and the second embedded part and is used for sealing the exposed surfaces of the first embedded part and the second embedded part; a welding part is arranged in the sliding sticking part, and the welding part is used for welding the first embedded part and the second embedded part and melting the sliding sticking part at a high temperature, so that the first embedded part, the welding part and the second embedded part are conveniently welded into an integrated structure in the later period. The embedded parts are covered through the sliding pasting parts, sliding settlement of the embedded parts and sliding settlement of the embedded parts are facilitated, and the first embed
