The invention belongs to the field of tunnel connecting pieces, and particularly relates to a tunnel embedded sideboard splicing seam pouring device which comprises a tunnel body. An embedded side plate is fixedly connected to the joint of the inner side walls of the pair of tunnel bodies. A base is arranged in the tunnel body; the middle part of the base is rotationally connected with a telescopic rod; the end, away from the base, of the telescopic rod is fixedly connected with a connecting block. The side wall of the middle of the connecting block is rotationally connected with a cam. Through rolling of the cams, cement between the pre-buried side plates and the tunnel body can be vibrated, so that internal air is moved and discharged under the vibration effect, air in the cement is reduced, the structural strength of the cement after the cement is dried and hardened is improved, and internal cavities are reduced. 本发明属于隧道连接件领域，具体的说是一种隧道用预埋边板拼接缝浇筑装置，包括隧道本体；一对所述隧道本体内部侧壁交接处固接有预埋边板；所述隧道本体内部设有底座；所述底座中部转动连接有伸缩杆；所
