Bridge fabrication machine and bridge block construction method

The invention provides a bridge fabrication machine and a bridge block construction method. The bridge fabrication machine comprises a main beam, a hanging basket system, a jacking system and a walking system. The hanging basket system comprises an outer mold, an outer mold longitudinal beam, a bottom mold platform, an inner mold and an inner mold longitudinal beam, and the bottom mold platform, the outer mold and the inner mold are enclosed to form a bridge block pouring mold; the jacking system is used for supporting the main beam; the walking system comprises a track, a walking driving piece, a support, a rolling wheel, a connecting frame, a reverse buckling wheel, a balance wheel and a front hanging wheel. According to the bridge fabrication machine provided by the invention, the lengths of the inner mold and the outer mold are 8-9.5 m, the length of a bridge block poured at a time is large, the construction frequency can be reduced, the construction efficiency can be improved, the overall consumed time i
