Abstract

This invention discloses a crash barrier, belonging to the field of traffic facility technology. The crash barrier includes a base for counterweight, with a column fixed or inserted onto the base. At least one cylindrical body for crash protection and energy absorption is fixedly or rotatably mounted on the column. The base can be a one-piece molded structure or a hollow shell structure filled with counterweight material. The cylindrical body has an elastic structure or energy-absorbing structure inside. Warning and data collection modules and signs can be installed on the column. This invention features a modular design for easy installation, maintenance, and component replacement; multiple base structures adapt to different scenarios; stable counterweight resists displacement; a multi-stage energy-absorbing structure significantly improves the crash protection effect; and integrated sound and light warning and information collection functions result in a high degree of intelligence, making it suitable for traffic intersections, guardrail ends, and other locations.
