AI Technical Summary
Technical Problem
When the existing grouting sleeve connection method is assembled by bridges, the joint surfaces of adjacent sub-pier columns are easily weaker than those of the ultra-high pier, resulting in a reduction in the overallity of the bridge and insufficient seismic resistance.
Method used
A tie beam is provided in the ultra-high piers of the bridge, and adjacent sub-piers are fixedly connected to the tie beam through a grouting sleeve, and an adhesive layer is provided between the grouting sleeve and the connector to enhance the connection strength and stability.
Benefits of technology
The beams bear the lateral load of the ultra-high piers, reduce load bearing, enhance lateral stiffness, and improve the bridge's seismic performance and lateral force resistance.

Abstract
The invention discloses a bridge and a prefabricating and assembling method for a high-performance ultrahigh pier with a tie beam, the bridge comprises the ultrahigh pier, the ultrahigh pier comprises a plurality of sub-pier columns, each sub-pier column is fixedly provided with at least one first connecting piece, and each first connecting piece is arranged in the corresponding sub-pier column in a penetrating mode in the height direction of the sub-pier column; the straining beams are arranged between every two adjacent sub-pier columns of the ultrahigh pier; the first connecting pieces corresponding to the adjacent sub-pier columns are fixedly connected through the grouting sleeves, and the grouting sleeves are fixed to the straining beam, so that the straining beam and the two adjacent sub-pier columns are fixed together; a bonding layer is arranged between the grouting sleeve and the first connecting piece, and the first connecting piece and the grouting sleeve are fixed through the bonding layer. In the bridge, the straining beams are arranged between the adjacent sub pier columns, so that the straining beams can bear the transverse load borne by the ultrahigh pier, the load borne by the ultrahigh pier is reduced, the overall transverse rigidity of the ultrahigh pier is enhanced, and the overall performance of the ultrahigh pier is effectively improved.
