Combined protective pier for concrete viaduct
The invention provides a combined protective pier for a concrete viaduct and belongs to the field of road-bridge traffic safety facilities. The combined protective pier comprises a soft cushion layer,a protective bent sleeve plate, a cushioning bent sleeve plate, an impact-resistant bent sleeve plate, a protective bent plate base plate, a cushioning bent plate base plate and the like. A pier column and the protective bent sleeve plate are connected through a plurality of supporting connecting rods. A plurality of compressive deformation-resistant energy-absorbing inner-layer assemblies are arranged between the protective bent sleeve plate and the cushioning bent sleeve plate; a plurality of anti-compression-deformation energy-absorbing outer-layer assemblies are arranged between the cushioning bent sleeve plate and the impact-resistant bent sleeve plate, connecting bearing beads are arranged between the soft cushion layer and the impact-resistant bent sleeve plate, cushioning springsare arranged between the soft cushion layer and outer-layer connecting nails, and shear thickening glue filling layers are arranged in the rest spaces of the soft cushion layer and the impact-resistant bent sleeve plate. The damping effect and ductility can be well improved while large deformation can be borne, and impact collision energy can be fully dissipated when a vehicle body collides with apier main body structure.
本发明提供了一种混凝土高架桥组合防护墩，属于路桥交通安全设施领域，包括软垫层、保护弯折套板、缓震弯折套板、抵抗冲击弯折套板、保护折板基板、缓震折板基板等,所述桥墩柱和保护弯折套板之间经若干撑连杆相连，在保护弯折套板和缓震弯折套板之间设置若干抗压变形吸能内层组合件，在缓震弯折套板和抵抗冲击弯折套板之间设置若干抗压变形吸能外层组合件，在软垫层和抵抗冲击弯折套板之间设置连接承珠，在软垫层和外层连接钉之间设置缓震簧，在软垫层和抵抗冲击弯折套板的其余空间设置剪切增稠胶填充层。本发明能承受较大变形的同时可以很好的增大阻尼效果和延性能力，能在车体和桥墩主体结构发生撞击时充分耗散冲击碰撞能量。
