The expansion plate is supported by the step surfaces of the beams on both sides of the expansion joint, the support rods and the arched support body. The arched support body and the support rods are steel structural parts, the pavement layer is an elastic material layer, and the pavement layer is a structural layer with mechanical functional gradient performance.

When the bridge is deformed by thermal expansion and contraction, the first fixing plate 1 and the second fixing plate 2 are deformed and moved. At this time, the gap between the plurality of first meshing plates 3 and the plurality of second meshing plates 4 is used for buffering. At the same time, in the process of the movement of the plurality of first meshing plates 3 and the plurality of second meshing plates 4, the first fixing plate 1 and the second fixing plate 2 are limited by sliding the guide rod 5 in the guide hole. In order to avoid the meshing between the plurality of first meshing plates 3 and the plurality of second meshing plates 4 from falling off when the device is subjected to forces in different directions, the filtering structure includes a mounting frame 7 and a filter screen 8. Two mounting plates 9 are fixedly connected to the first fixed plate 1 and the second fixed plate 2. Four mounting plates 9 are provided with insertion ports. The mounting frame 7 is slidably connected in the insertion ports. The filter screen 8 is mounted in the mounting frame 7. The mounting frame 7 is inserted through the insertion ports respectively provided on the four mounting plates 9. The filter screen 8 is inserted through the mounting frame 7. During use, the sewage flowing out through the gaps between the plurality of meshing plates and the plurality of second meshing plates 4 is filtered through the filter screen 8. At the same time, during the cleaning process, the mounting frame 7 is removed from the insertion port. In order to realize the disassembly of the installation frame 7 and the filter screen 8, the device also includes multiple first shock-absorbing springs 10 and multiple second shock-absorbing springs 11. The multiple first shock-absorbing springs 10 are all connected to the corresponding first meshing plates 3, and the other ends of the multiple shock-absorbing springs are all connected to the second fixed plate 2. The multiple second shock-absorbing springs 11 are all connected to the corresponding second meshing plates 4, and the other ends of the multiple second shock-absorbing springs 11 are all connected to the first fixed plate 1. When the device causes thermal expansion and contraction to cause deformation, the multiple first meshing plates 3 and the multiple second meshing plates 4 move. At this time, the multiple first shock-absorbing springs 10 and the multiple second shock-absorbing springs 11 are all squeezed, and the buffering effect is achieved by the multiple first shock-absorbing springs 10 and the multiple second shock-absorbing springs 11.
[0025] To sum up, the working principle and working process of the bridge expansion joint structure and its construction device are as follows: when in use, the device is moved to a suitable position, and the multiple first meshing plates 3 and the multiple second meshing plates 4 are respectively fixed by the first fixed plate 1 and the second fixed plate 2, so that the multiple first meshing plates 3 and the multiple second meshing plates 4 cooperate with each other to form an expansion joint structure, and the device is cast into the bridge body by multiple casting rods 6. When the bridge expands and contracts due to heat, the bridge squeezes the first fixed plate 1 and the second fixed plate 2 to move, and buffers are performed through the gaps between the multiple first meshing plates 3 and the multiple second meshing plates 4. During the buffering process, the guide rod 5 slides in the guide hole to achieve limiting, so as to avoid shaking and falling off of the device when subjected to forces in different directions. At the same time, during use, the impurities passing through the gaps of the device are filtered through the filter net 8.
