Anti-seismic device for large aqueduct and large aqueduct
The invention discloses an anti-seismic device for a large aqueduct and the large aqueduct, the large aqueduct is provided with a duct pier and a duct body, a support is arranged between the duct pier and the duct body, the anti-seismic device comprises a first connecting seat, a second connecting seat and a shock absorber, the first connecting seat is arranged on the duct body, the second connecting seat is arranged on the duct pier, and the shock absorber is arranged on the first connecting seat. The first connecting base and the second connecting base are arranged in a spaced mode in the first direction, and the shock absorber is connected between the first connecting base and the second connecting base and can slide in the second direction relative to the first connecting base and the second connecting base. Therefore, the shock absorber can slide in the second direction relative to the first connecting base and the second connecting base so as to adapt to the deformation direction when the support deforms under the temperature influence, and the shock absorber is prevented from hindering deformation of the support; meanwhile, under the condition of small earthquakes, the stress deformation direction of the shock absorbers is the same as that of the support, so that the earthquake force borne by the support is reduced, the risk that the support is damaged is reduced, and under the condition of large earthquakes, the shock absorbers can yield to dissipate energy and absorb earthquake energy transmitted to the support, so that the risk that the groove piers collide with the groove body is reduced.
本发明公开了一种用于大型渡槽的抗震装置和大型渡槽，大型渡槽具有槽墩和槽身，槽墩和槽身之间设有支座，抗震装置包括：第一连接座、第二连接座和减震器，第一连接座设于槽身，第二连接座设于槽墩，且第一连接座和第二连接座在第一方向上间隔设置，减震器连接在第一连接座和第二连接座之间，且减震器可相对第一连接座和第二连接座沿第二方向滑动。由此，通过使得减震器可以相对第一连接座和第二连接座沿第二方向滑动，以适应支座在温度影响下发生变形时的变形方向，防止减震器对支座的变形产生阻碍；同时在小震情况下，减震器的受力变形方向与支座的受力变形方向相同，以减小支座受到的地震力，降低支座被破坏的风险，在大震情况下，减震器可以屈服耗能，吸收向支座传递的地震能量，以降低槽墩与槽身发生碰撞的风险。
