step four: after coating, mixing concrete and high-strength foaming resin required in the pouring forming process of the track slab body (4), after mixing, transporting to one side of a shaping steel die, detecting the temperature of the concrete before pouring, controlling the temperature of the concrete to be between 5 and 30 ℃, pouring the concrete into the shaping steel die after detecting, vibrating the concrete by using a vibrating rod in the pouring process, increasing the forming effect of the track slab body (4), detecting the pouring height of the concrete according to the processing requirement after pouring, and troweling the surface of the concrete;
step five: and (3) cooling and forming the concrete in the fixed steel mould, removing the fixed steel mould and the embedded part from the track slab body (4) after forming, and after finishing removing, adopting a standard maintenance procedure to perform steam maintenance on the track slab, and finishing maintenance to realize production.
