Embedded type self-resetting anti-seismic energy dissipation type pier
The top of four pile foundations is provided with the same bearing platform, the top of the bearing platform is provided with a rectangular groove, the inner wall of the bottom of the rectangular groove is slidably provided with a rubber pad, the top of the rubber pad is provided with a pier column, and the outer wall of the pier column is fixedly connected with a connecting ring; a plurality of second fixing blocks are fixedly connected to the outer wall of the connecting ring, and first viscous dampers are rotationally connected between the second fixing blocks and the bearing platform. The first buffering mechanism is arranged at the top of the bearing platform and used for buffering the rubber pad, so that the rubber pad eliminates part of seismic force on the pier column; the second buffering mechanism is arranged between the bearing platform and the pile foundation and used for supporting the bearing platform to further buffer seismic force; the problems that when an existing bridge pier is subjected to an earthquake, the bridge pier can deform to a certain degree, the deformation square is random, if buffering energy dissipation is not carried out, the joint of the bridge pier and a bearing platform is prone to breakage, and the energy dissipation effect is small are solved.
本发明涉及一种嵌合式自复位抗震消能型桥墩，四个桩基的顶部设有同一个承台，承台的顶部开设有矩形槽，矩形槽的底部内壁滑动设有橡胶垫，橡胶垫的顶部设有墩柱，墩柱的外壁固定连接有连接环，连接环的外壁固定连接有多个第二固定块，第二固定块与承台之间转动连接有第一粘滞阻尼器；第一缓冲机构，设置在承台的顶部用于对橡胶垫缓冲，使其进行对墩柱消除部分地震力；第二缓冲机构，设置在承台和桩基之间，用于对承台支撑进一步缓冲地震力；解决现有桥墩受到地震时，桥墩会发生一定的形变，其形变方形随意，如不进行缓冲消能，容易使桥墩与承台连接处断裂，并且消能作用较小的问题。
