A piston plate 36 is slidably connected to the interior of the second circular groove 37.

[0043] A construction method for a connection structure for connecting an abutment to a bank specifically includes the following steps:

[0044] S1. Pier production: Send the circular seat 19 into the installation hole 7, sequentially insert the arc-shaped plates 6, and use the inclined surface structure to push the arc-shaped blocks 21 into the grooves to realize the stable installation of the arc-shaped plates 6. Then cover the annular limiting plate 13 and fill with crushed stones and concrete to make the pier;

[0045] S2. Bridge deck 4 positioning: After the pier is completed, cover the cover plate 3, use the threaded connection between the annular groove 10 and the annular limiting plate 13 to ensure stability, place one end of the bridge deck 4 on the cover plate 3, fix it through the screw rod 11 and the fixing nut 12, and use a crane to adjust the angle of the bridge deck 4 to the preset position;

[0046] S3. Shock Absorption and Safety Monitoring: After the bridge deck 4 is installed, its slight vibration is cushioned by structures such as the slider 28, the second spring 29, and the friction pad 41. When the slider 28 moves to the extreme position, it triggers the alarm to achieve safety monitoring.

[0047] When the connecting structure for connecting the bridge abutment to the bank is in use, the circular seat 19 is inserted into the inner part of the installation hole 7, and a plurality of arc-shaped plates 6 are sequentially inserted into the inner part of the installation hole 7. At this time, the arc-shaped plate 6 drives two rectangular blocks 22 to push the arc-shaped block 21. The rectangular block 22 contacts the inclined surface of the arc-shaped block 21. At this time, the arc-shaped block 21 squeezes the first spring 25 and enters the inner part of the first groove 20. The rectangular block 22 moves into the inner part of the second groove 26. When the rectangular block 22 no longer squeezes the arc-shaped block 21, at this time, the arc-shaped block 21 rises under the elastic force of the first spring 25. At this time, the arc-shaped block 21 drives the side plate 24 to rise, and the side plate 24 uses the rectangular groove 23 to position the rectangular block 22 to ensure the stability of the installation of the arc-shaped plate 6.

[0048] After a plurality of arc-shaped plates 6 are installed in sequence, at this time, the annular limiting plate 13 can be covered on the plurality of arc-shaped plates 6. The annular inner plate 14 abuts against the inner wall of the arc-shaped plate 6. The annular limiting plate 13 presses on the top of the plurality of arc-shaped plates 6, and the stability of the connection of the plurality of arc-shaped plates 6 is ensured by the clamping of the insertion block 15 and the insertion slot 16. At this time, gravel can be put into the cavity formed by the plurality of arc-shaped plates 6, and then concrete is poured to fill the voids to make the bridge pier. And when putting the gravel, the round rod 17 can be continuously pulled up and down. The round rod 17 drives the round plate 18 to move up and down. At this time, the round plate 18 can help the gravel vibrate, avoid the accumulation of stones and large voids, and improve the strength of the device.

[0049] After the bridge pier is made, the cover plate 3 can be covered on the annular limiting plate 13. At this time, the annular groove 10 is threadedly connected to the annular limiting plate 13 to ensure the stability of the connection between the cover plate 3 and the annular limiting plate 13. One end of the bridge deck 4 is placed on the cover plate 3, and the screw rod 11 passes through the round hole 8, and the fixing nut 12 is fixed between the two support seats 5 by using two fixing nuts 12. At this time, the crane can lift one end of the bridge deck 4 away from the support seat 5, and the end of the bridge deck 4 close to the support seat 5 abuts against the top of the cover plate 3. The bridge deck 4 cannot continue to rotate after rotating to the preset angle, which can help to position the bridge decks 4 on both sides of the river and facilitate the subsequent construction.

[0050] After the bridge deck 4 is installed, the bridge deck 4 does not directly act on the river embankment 2, which can improve the service life of the river embankment 2. And when the bridge deck 4 has slight vibration, the bridge deck 4 will push the slider 28 to move horizontally. The slider 28 squeezes the second spring 29 and drives the friction pad 41 to move horizontally. The friction pad 41 continuously generates friction with the inner wall of the chute 31 and the continuously popped strip-shaped block 32, thereby achieving the damping effect.

[0051] Synchronously, the slider 28 drives the two push rods 27 to move horizontally. The push rods 27 drive the spherical block 40 to move horizontally. The spherical block 40 is arranged to facilitate insertion into the first circular groove 33. After the spherical block 40 enters the first circular groove 33, it pushes the piston plate 36 to move horizontally. The piston plate 36 slides inside the second circular groove 37 and squeezes the internal air to achieve a damping effect. And after the piston plate 36 resets, the air hole 34 ensures the stability of the air pressure inside the piston plate 36. After the slider 28 moves to the farthest distance, it will squeeze the elastic switch 35, thereby triggering the alarm connected thereto to achieve the alarm function for reminding the staff.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the present technical solution, and they should all be covered within the scope of the claims of the present invention.
