Zusammenfassung:	The utility model discloses a pipeline switching mechanism, a pipeline switching device and a concrete spreader, and relates to the technical field of tunnel lining. The pipeline switching mechanism comprises an inserting assembly, a first driving assembly and a second driving assembly. The first driving assembly comprises a first rotating piece and a first driving source. The first driving assembly comprises a first rotating piece and a first driving source, the second driving assembly comprises a second rotating piece and a second driving source, the inserting assembly, the first rotating piece and the second rotating piece are sequentially connected, the first driving source drives the first rotating piece and the inserting assembly to rotate around a first central axis at the same time, and the second driving source drives the second rotating piece to rotate around a second central axis. The second driving source drives the second rotating piece, the first rotating piece and the inserting assembly to rota
