The whole implementation process of the invention is as follows; the trolley moves to a preset lining position and then clamps the rail clamping device tightly, the foundation jack is screwed out, the jack is tightly pressed on the rail surface of the steel rail (if a jacking ground jack exists, the jacking ground jack is required to be installed and then screwed), the vibration generated when the moving mechanism 2 moves enables the connecting plate 4.04 to fluctuate up and down along the direction of the guide rod 4.03, and the elastic piece A4.02 buffers and eliminates the fluctuation to reduce the vibration. The external surface, the working window and the grouting opening of the concrete front trolley template 1 need to be pre-coated with a release agent so as to reduce the surface adhesion of the template during demoulding. When pouring concrete, feeding the concrete from the lowest row of working windows of the side template 1, closing the working windows when pouring the concrete to be level with the working windows, and then pouring the concrete from the second row of working windows. And by parity of reasoning, finally, sealing the top through a grouting opening. After the pouring is finished, the concrete is solidified for a certain time and then is demoulded. When the machineshop car transports the concrete into the platform truck, the continuous monitoring machineshop car of sensor 9 or other vehicles is for the distance of portal business turn over side, when the vehicle is close to portal 3 certain distance, sensor 9 signals gives the controller, controller control siren 5 sounds, warning light 8 glimmers, reminds the driver to control the vehicle, if hit portal 3 when, buffer gear 7 cushions the dashing and hits, reduces the injury that the lining cutting platform truck received.
