The invention belongs to the technical field of bridge protection devices, and particularly relates to a multi-stage buffer anti-collision pier. The multi-stage buffer anti-collision pier comprises apier body and an anti-collision body surrounding the pier body; the anti-collision body comprises a first-stage protection cylinder, a second-stage protection cylinder and a third-stage protection cylinder, wherein the first-stage protection cylinder surrounding the pier body, and the first-stage protection cylinder comprises the outer cylinder body and the inner cylinder body which are sequentially arranged from outside to inside; the outer wall of the second-stage protection cylinder abuts against the inner wall of the inner cylinder body of the first-stage protection cylinder; and the outerwall of the third-stage protection cylinder abuts against the inner wall of the inner cylinder body of the first-stage protection cylinder, a guide mechanism is arranged on the outer wall of the third-stage protection cylinder, and after the first-stage protection cylinder is impacted, the guide mechanism can drive the first-stage protection cylinder to rotate, so that an impacted object deviates. After a vehicle collides with the anti-collision pier, the first-stage protection cylinder absorbs a small part of energy firstly, then the remaining energy is completely absorbed by the second-stage protection cylinder, or the second-stage protection cylinder absorbs a part of energy, the remaining energy is discharged by the third-stage protection cylinder, and through multi-stage energy absorption, it can be effectively guaranteed that the pier body is not damaged, and damage to the vehicle can be reduced.
本发明属于桥梁防护装置技术领域，尤其涉及一种多级缓冲防撞墩，包括桥墩以及环绕桥墩设置的防撞体，防撞体包括一级防护筒，包围桥墩设置，一级防护筒包括由外向内依次设置的外筒以及内筒；二级防护筒，且其外壁抵触于一级防护筒的内筒内壁上；三级防护筒，其外壁抵触于一级防护筒内筒的内壁上，三级防护筒的外壁上设置有引导机构，在一级防护筒受撞击后，引导机构可带动一级防护筒转动，使撞击物发生偏移。车辆撞击到防撞墩上后，一级防护筒先吸收小部分能量，然后剩下的能量由二级防护筒全部吸收，或者是二级防护筒吸收一部分能量，其余的由三级防护筒进行卸能，通过多级能量吸收，不仅能够有效的保障桥墩不受损伤，而且还能减少车辆的损伤。
