[0034] (3) In the application, after the inner mold assembly is integrally removed, the inner mold assembly walks on the concrete surface of the inner wall of the poured aqueduct by relying on the self-provided guide wheels, without needing to additionally provide a track, so that the construction quality is improved, the labor intensity is reduced, the construction efficiency is greatly improved, and high safety and reliability are achieved. The inner mold assembly takes two center main beams as the formwork force receiving points, the support forces on the left and right sides are offset to each other, and the downward pressure not only relies on the end mold but also has the gravity of the inner mold assembly itself.

The setting of the column guides the sleeve to move up and down along the column during the lifting of the support wheel, so as to avoid affecting the vertical lifting of the mechanical jack by the force in the front and back directions.
