Abstract

The invention provides a primary-secondary type central crash barrier system capable of being opened and closed. The system is provided with a fixed primary central crash barrier system, a movable secondary crash barrier system and an embedded traction system, wherein the three systems cooperate with one another, a secondary steel anti-collision box body structure can be collected into the primaryanti-collision system through the embedded traction system in emergency, and then a section of road median strip is vacated for a U-turn vehicle to run. The central crash barrier system adopts prefabricated assembly, is high in assembly rate and short in construction period, can be overhauled in the operation period, does not waste land, and has good economic benefits and landscape effects. The traffic requirement of a U-turn lane can be quickly met in case of an emergency, the U-turn problem of vehicles in expressways and urban expressway engineering can be effectively solved, a lot of rescue time is saved, and the guarantee strength of property and life safety of people is enhanced.

Description

technical field [0001] The invention belongs to the technical field of road engineering, and in particular relates to a mother-in-two type central anti-collision barrier system which can be opened and closed. Background technique [0002] At present, there are a large number of fixed central anti-collision barriers in urban expressways and expressways. When an emergency accident occurs during the driving of a vehicle, it is often necessary to drive to the next entrance and exit to complete the conversion of the driving direction. In practice, it is wasted A large amount of rescue time is not enough to protect people's property and life safety, there are problems of wasting manpower and time, and the conversion efficiency of traffic functions is low. [0003] In order to solve the above-mentioned problem of traffic conversion and save the emergency treatment time in the event of an emergency, there is an urgent need for a central anti-collision separation structure with a hig...
