Description
Technical Field
The application belongs to the technical field of buffering energy-absorbing device, and more specifically relates to a novel anti-collision column.
Background
According to statistics, China has a considerable number of road traffic accidents every year. Especially, accidents in personnel dense areas such as safety islands and sidewalks often cause great influence. Taking the safety island as an example, only Shenzhen city has 5 similar traffic accidents since 2019, so that a plurality of casualties are caused, which rings an alarm clock for road traffic safety in China and simultaneously shows that: the function of the safety island as a guarantee for the life safety of pedestrians is not fully exerted, and even becomes an adventure island in some cases. A large number of accidents caused by the fact that vehicles run away from control and collide with a safety island and a sidewalk in China show that the existing safety protection facilities are insufficient in crashworthiness design and lack of relevant standards and regulations matched with the existing safety protection facilities.
The primary objective of safety protection facilities in traffic-intensive areas such as safety islands and sidewalks is to prevent vehicles from intruding, i.e. to ensure that the safety protection facilities have sufficient impact resistance, but if the vehicles are impacted by the anti-collision columns, the anti-collision columns must be extremely heavy and have poor economical efficiency. At present, the upright columns installed on occasions such as traffic islands, sidewalks and the like are hollow thin-walled tubes and only can play a role in separation warning, and the impact resistance is obviously insufficient, or the upright columns are solid stone piers, are insufficient in height and large in weight, are easy to break during impact, and cannot effectively play a role in blocking. In some occasions, the solid steel column is replaced by the devices for improving the shock resistance, so that the weight is greatly increased, the cost is high, the construction is inconvenient, and the shock resistance is enhanced to some extent, but the device is heavy and is not suitable for large-area installation and application.
