The invention relates to the field of embedded channels, in particular to an embedded channel with a limiting device and an installation method of the embedded channel. The embedded channel with the limiting device comprises a channel body and further comprises a first limiting piece, the first limiting piece is used for being connected with lining steel bars of a tunnel, the channel body and the first limiting piece are connected through a connecting piece, and the connecting piece and the first limiting piece can relatively slide in the length direction of the connecting piece. The channel body moves along the axis of the connecting piece to be close to or away from the first limiting piece. When the embedded channel is installed, the embedded channel is preliminarily fixed to the lining steel bar at the preset position for positioning through the first limiting piece, and compared with the prior art that the embedded channel is directly positioned through hole forming of a lining trolley, positioning can b
