AI Technical Summary
The existing bridges connecting to the newly built embankments have poor buffering effects and cannot effectively absorb the horizontal forces caused by river scouring and traffic flow, resulting in a reduced service life.
The system employs a combination structure of buffer and connection parts, including components such as dampers, connecting discs, support columns, and compression springs. The damper absorbs impact forces through fluid flow and the spring's extension and contraction, while the connection part's interlocking mechanism compensates for temperature changes, thus achieving a stable connection.
It improved the buffering effect at the connection between the bridge and the river embankment, extended the overall service life, ensured the smooth passage of vehicles and pedestrians, and reduced the risk of structural damage.
