The friction supports 4 are "U" shaped structures. After the prefabricated platform board 2 is placed on the friction supports 4, the length direction of the prefabricated platform board 2 is consistent with the forward direction of the transfer vehicle. Subsequently, the prefabricated platform board 2 can be matched with the platform board installation groove by only adjusting the forward direction of the transfer vehicle, which is convenient for the installation of the prefabricated platform board 2.

[0028] A method for installing a prefabricated platform slab for an urban rail transit project, using the above-mentioned prefabricated platform slab installation device for an urban rail transit project, comprises the following steps:
