The invention discloses an anti-sinking bridge. The bridge comprises a bridgehead, a bridgehead connecting plate arranged on the bridgehead, a vehicle tripping prevention device connected with the bridgehead and the bridgehead connecting plate, a damping device arranged on the vehicle tripping prevention device, a bridge pier arranged in front of the bridgehead, a bearing table fixedly connected with the bridge pier, a compensation device arranged on the bearing table, a bridge plate arranged on the bearing table, lapping plates arranged on the two sides of the bridge plate, an external forcedredging device arranged in the bridge plate, and a limiting device arranged below the lapping plates. The vehicle tripping prevention device is arranged on the bridgehead connecting plate, so that adjustability of connection of the bridgehead and the bridge plate is realized, and the phenomenon of vehicle tripping of the bridgehead caused by natural settlement of a bridge is effectively prevented; and the external force dredging device is arranged, longitudinal loads borne by the single pier are dispersed through a mechanical means, concentrated loads are dispersed into local loads, and bridge sinking caused by passing of automobiles is reduced.
本发明公开了一种防下沉桥梁，包括桥头、设于所述桥头的桥头接板、连接所述桥头与桥头接板的放跳车装置、设于所述防跳车装置的减震装置、设于所述桥头前方的桥墩、固定连接与所述桥墩的承重台、设于所述承重台上的补偿装置、设于所述承重台上的桥板、设于所述桥板两侧的搭板、设于所述桥板内部的外力疏导装置和设于所述搭板下方的限位装置。本发明通过在桥头接板设置防跳车装置，实现了桥头与桥板衔接的可调节性，有效防止了桥梁自然沉降引起的桥头跳车现象；设置了外力疏导装置，通过机械手段将单个桥墩所受的纵向载荷分散，使集中载荷分散为局部载荷，减少了汽车通过所引起的桥梁下沉。
