[0028] This utility model provides a technical solution, please refer to Figure 1-4 : A roadbed pad includes a roadbed pad body 1, a connecting groove 2, a fixed connecting column 3, an anti-slip block 4, a positioning groove 5, a fixed connecting plate 6, a limiting groove 7 and a fixed connecting pin 8.

[0029] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the lower end of the fixed connecting column 3 is fixedly connected with an anti-slip block 4, and the lower end of the fixed connecting column 3 is inserted into the roadbed, and the anti-slip blocks 4 are arranged at equal intervals on the fixed connecting column 3, and the fixed connecting plate 6 is connected through the positioning groove 5, and a limiting groove 7 is provided on the inner side of the upper end of the fixed connecting plate 6. First, the fixed connecting plate 6 is engaged in the positioning groove 5 between the roadbed pad body 1 at the adjacent position and the roadbed pad body 1, and the lower end of the fixed connecting plate 6 is fixedly connected with a fixed connecting pin 8, and then the roadbed pad body 1 is laid flat on the roadbed, and the fixed connecting plate 6 drives the fixed connecting pin 8 to be inserted into the roadbed, which facilitates the positioning between the roadbed pad body 1 and the roadbed. Combined with the setting of the fixed connecting plate 6, it is convenient to connect the roadbed pad body 1 at adjacent positions with the roadbed pad body 1, and the integrity is good.

[0030] Example 2

[0031] This utility model provides a technical solution, please refer to Figure 1-6 : A road structure composed of a roadbed pad, including a roadbed pad body 1, a connecting groove 2, a fixed connecting column 3, an anti-drop block 4, a positioning groove 5, a fixed connecting plate 6, a limiting groove 7, a fixed connecting pin 8, a mounting mechanism 9, an auxiliary plate 10, a return spring 11, a movable connecting column 12, a fixed connecting rod 13 and a pull ring 14;
