When the pushing rod 49 is squeezed and moves into the T-shaped groove 48, the pushing rod 49 will drive the bar gear plate 3 51 to move, and the spring 2 50 will generate elastic force. Through the meshing connection relationship between the bar gear plate 3 51 and the gear 3 52, the gear 3 52 will rotate.

Then, the electric push rod 14 is started to drive the lifting swing arm assembly and the prefabricated track plate 7 to move upward synchronously, and the support plate 5 is moved through the moving seat 6, so that the prefabricated track plate 7 is moved to the position to be laid above the geotextile 4, and then the electric push rod 4 45 is started to move the electric push rod 4 45 to the upper position of the pressure plate 65, and then the electric push rod 14 is started to make the lifting plate 15 drive the prefabricated track plate 7 to move downward. When the outer wall of the electric push rod 4 45 touches the top of the pressure plate 65, the electric push rod 14 is stopped, and then the motor 56 is started. The motor 56 drives the gear 4 57 to rotate. Through the meshing connection relationship between the gear 4 57 and the gear ring 55, the gear ring 55 drives the rotating ring 54 to rotate, and the rotating ring 54 drives the T-ring to slide inside the annular groove, and then the gear ring 54 is engaged.

Then the plug-in plate 46 is disconnected from the prefabricated track plate 7, and the clamping of the pressure plate 65 on the side walls of the prefabricated track plate 7 is disconnected. Then the support plate 5 is moved by the moving seat 6, so that the sliding seat 64 can be moved to the middle of the track plate 7 located in the middle position. At the same time, the sliding seat 64 will drive the pressure plate 65 to move synchronously, and then the pressure plate 65 can clamp the side walls of the three prefabricated track plates 7, and make the pressure plate 65 located at the top of the base plate 3, so as to wrap the bottom of the three prefabricated track plates 7, and then move away from each other.
