The invention relates to the technical field of highway protective fences, and discloses a highway bridge protective fence. The highway bridge protection fence comprises a protection fence frame, an energy absorption structure is installed on one side of the protection fence frame, an arc-shaped buffer frame is installed at one end of the energy absorption structure, an arc-shaped inner groove is formed in the inner side of the protection fence frame, and the energy absorption structure comprises an outer shell, a pressure inner cavity, a pressure transmission shaft, a sealing ring and a thick radial flow groove. A pressure transmission shaft is installed at one end in the pressure inner cavity, a sealing ring is arranged at one end of the pressure transmission shaft, a thick radial flow groove is further formed in the sealing ring, and supporting side plates are symmetrically arranged at one end of the outer shell of the energy absorption structure. Flow acting force located in the thick runoff groove is provided for oil through thrust of the pressure transmission shaft, so that the thrust of the pressure transmission shaft is converted into flow speed driving force of liquid, the impact acting force can be greatly buffered in the mode, and the device can have the buffering effect of large impact force.
本发明涉及公路防护栏技术领域，且公开了一种公路桥梁保护栏。该公路桥梁保护栏包括护栏架，护栏架的一侧安装有吸能结构，吸能结构的一端安装有弧形缓冲架，护栏架的内侧设有弧形内凹槽，吸能结构包括外壳体、压力内腔、压力传递轴、密封圈和粗径流槽，外壳体的内部设有压力内腔，压力内腔内部的一端安装有压力传递轴，压力传递轴的一端设有密封圈，密封圈的内部还设有粗径流槽，吸能结构的外壳体的一端对称设有支撑侧板。本发明通过压力传递轴的推力，为油液提供位于粗径流槽内部的流动作用力，从而使压力传递轴的推力转变成液体的流速驱动力，而此方式，可大幅度缓冲撞击的作用力，使装置能够具备较大撞击力的缓冲作用。
