Obviously, the described embodiments are only some embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present application.

[0028] As Figure 1 shown, the high-speed rail box girder retaining wall concrete conveying vehicle of the embodiment 1 of the present application is used for being arranged on the box girder 5 and used for pouring concrete into the retaining wall pouring cavity of the box girder 5.
