[0025] When the bearing plate 2 is extruded, the second connecting plates 5 can be synchronously moved by a small amount, the reinforcing plates 3 are pulled to form clamping and reinforcing effects on the roadbed body 1 through the cooperation of the wedge blocks 8 and the wedge grooves 7, and the bottom of the second connecting plates 5 is limited through the cooperation of the tensioning screws 9, the waist grooves 11 and the stop blocks 12, so that the second connecting plates 5 are prevented from being extruded to form outward expansion deformation.

[0026] Both sides of the bearing plate 2 are fixedly connected with extension frames 13, and the reinforcing plates 3 are fixedly connected with reinforcing ribs 14 at equal distances.

[0027] The sliding blocks 15 are inserted between the reinforcing ribs 14 and attached to the reinforcing plates 3.

[0028] The sliding blocks 15 are pressed against the surfaces of the reinforcing plates 3 through the extension frames 13, so that the sliding blocks 15 can extrude the reinforcing plates 3 when the bearing plate 2 is extruded, thereby forming further clamping and reinforcing effects.

[0029] Positioning notches 16 are arranged on the reinforcing ribs 14 at the same level as the tensioning screws 9, and fixed cross beams 17 are arranged in the positioning notches 16.

[0030] Both ends of the tensioning screws 9 horizontally penetrate the corresponding fixed cross beams 17 and are threadedly connected with self-locking nuts 10, the self-locking nuts 10 can be arranged in multiple numbers to increase the stability of the connection, the self-locking nuts 10 are extruded on the fixed cross beams 17, and circular holes for the tensioning screws 9 to penetrate are arranged on the fixed cross beams 17 and the reinforcing plates 3.

The roadbed is a structure for bearing and transmitting track gravity and train dynamic action, is the basis of the track, and is an important building for ensuring train operation. The roadbed is a soil and stone structure, and will be subjected to vibration force and stress when the train runs thereon. These vibration force and stress cause slight deformation of the roadbed. The train running on the bearing plate 2 will be subjected to stress from top to bottom, which causes the bearing plate 2 and the roadbed body 1 to be subjected to stress compression deformation. When the bearing plate 2 is extruded, it can drive the second connecting plate 5 to move synchronously in a slight amount. The second connecting plate 5 pulls the reinforcing plate 3 through the cooperation of the wedge block 8 and the wedge-shaped groove 7, thereby forming a clamping and reinforcing effect on the roadbed body 1.
