Abstract
A bridge sliding device includes a slide rail assembly, a first sliding component on the rail, and a second sliding component on the first. The second component locks at the start of the first, and the bridge deck truss's weight causes the first component's end to tilt slightly, allowing it to easily cross the junction between the temporary support platform and the bridge pier. This facilitates the smooth crossing of both the first and second components over the junction. Once the first sliding component is in place, the second component unlocks and continues sliding, increasing the travel distance of the bridge deck truss. The device ensures smoother movement of the components, enhancing construction efficiency.
