Fabricated foam concrete filled dumbbell-shaped thin-walled pipe bridge pier anti-collision device
The invention discloses a fabricated foam concrete filled thin pipe self-buckling system bridge pier anti-collision device; when the device is collided, firstly, a corrugated plate disperses stress, the corrugated plate and regenerated rubber deform to dissipate energy, then a dumbbell-shaped self-buckling system can effectively dissipate energy through mutual friction and plastic deformation, and the impact effect of axle impact on a bridge pier and a vehicle is relieved. After foam concrete is injected into an aluminum pipe, deformation of the aluminum pipe can be restrained, and the impact resistance of a protection device is effectively improved. The dumbbell-shaped aluminum pipe self-buckling system and foam concrete cooperate for protection, rigidity and softness are combined, the bridge pier is protected against damage after being impacted, and the safety of the vehicle and personnel on the vehicle is protected. The device has the advantages of being low in strength, high in energy consumption, convenient to maintain and replace, small in occupied area, environmentally friendly and the like, and the anti-collision requirement of the pier can be met.
本发明公开了一种装配式泡沫混凝土填充薄管自卡扣系统桥墩防撞装置，在受到撞击时，首先是波纹板分散应力，波纹板与再生橡胶产生变形耗能，然后哑铃状自卡扣体系可通过相互摩擦与塑性变形有效耗能，缓解了车桥撞击对桥墩与车辆的冲击作用。在铝管内注入泡沫混凝土后可以约束铝管的变形，有效提高该防护装置的抗冲击性。哑铃状铝管自卡扣系统与泡沫混凝土协同防护，刚柔并济，既保护了桥墩在受到撞击后不至破坏，又保护了车辆与车上人员安全。此装置具有低强度、高耗能、便于维修更换、占地面积小、绿色环保等优点，能够满足桥墩防撞需求。
