The invention relates to a precast slab ballast bed construction method which comprises the following steps: preparation before use: firstly, processing a ballast bed slab and conveying the processedballast bed slab to a track laying base, installing a power supply cable in a tunnel, installing a transition tool in advance at a wellhead of the tunnel or pouring a section of base into the tunnel,and installing a concrete blanking pipeline at the wellhead; and blanking, transporting materials, transporting plates, grabbing plates, finely adjusting the plates, fixing the ballast bed slab, pouring concrete, and after construction is finished, removing the fixing tool and finely adjusting and installing the track. The method has the advantages that the precast slabs are transported to a construction working face to be rapidly installed and laid, and the method is a prefabricated track laying method for urban rail transit engineering, the laying method is simple, and the construction speedis high. The assembly type
