The invention relates to a plastic sealing construction trolley for a concrete faced rockfill dam. The plastic sealing construction trolley comprises a construction trolley, wherein traveling wheels are arranged at the bottom of the construction trolley; the construction trolley is connected with a main rack winch distributed at the top of a dam through a dragging cable; a seepage-proof cover reel and a neoprene stick reel are arranged on the construction trolley; the neoprene stick reel is located in front of the seepage-proof cover reel; a combined steel mould is arranged between the seepage-proof cover reel and the neoprene stick reel; and a wheel type ladder is hung on the rear part of the construction trolley. A method for performing plastic sealing construction on the concrete faced rockfill dam by adopting the construction trolley comprises a step of putting the loaded materials into a V-shaped slot reserved on a concrete face by the construction trolley according to a construction sequence, thereby realizing the plastic sealing construction for the concrete faced rockfill dam by utilizing the construction trolley. According to the device and the method provided by the invention, the construction difficulty is reduced, the construction process is simplified, the construction schedule is quickened and the construction quality of plastic sealing material filling is ensured.
