Bridge anti-collision device
The invention belongs to the technical field of bridge protection in bridge engineering, and relates to a bridge anti-collision device. Comprising at least two bridge anti-collision modules, and the at least two bridge anti-collision modules are spliced together and surround the periphery of a bridge; each bridge anti-collision module comprises a shell and an X-shaped dot matrix sandwich structure arranged in the shell; the shell is made of a carbon fiber reinforced composite material; the X-shaped lattice sandwich structure comprises an X-shaped core body assembly and foamed aluminum filled in the X-shaped core body assembly; semi-solid aluminum alloy slurry is poured into the X-shaped core body assembly to form the X-shaped lattice sandwich structure. Due to the fact that the foamed aluminum is poured and formed in the X-shaped core body assembly, the X-shaped core body assembly and the foamed aluminum jointly act to generate large plastic deformation, and the anti-collision energy absorption capacity is improved. In addition, the carbon fiber reinforced composite material is small in density, light in weight, high in specific strength and specific stiffness and resistant to corrosion, the carbon fiber reinforced composite material serves as the anti-collision shell, and the light-weight, high-strength, anti-collision and anti-corrosion functions are achieved.
本发明属于桥梁工程中桥梁防护技术领域，涉及一种桥梁防撞装置。包括至少两个桥梁防撞模块，至少两个桥梁防撞模块拼接在一起且围设在桥梁的外围；每个桥梁防撞模块包括外壳、设置在外壳内的X型点阵夹芯结构；外壳的材质为碳纤维增强复合材料；X型点阵夹芯结构包括X型芯体组件以及填充在X型芯体组件内的泡沫铝；通过将半固态铝合金浆料浇注进X型芯体组件形成X型点阵夹芯结构。由于在X型芯体组件内浇筑成型泡沫铝，X型芯体组件与泡沫铝共同作用发生大的塑性变形，提高防撞吸能能力。此外，碳纤维增强复合材料密度小、质量轻，具有较高的比强度、比刚度、具有耐腐蚀性能，将碳纤维增强复合材料作为防撞外壳，满足轻量高强，防撞防腐功能。
