Description
Technical Field
The invention relates to a highway guardrail protection technology, in particular to an energy-absorbing guide type anti-collision facility and a unit assembly suitable for a small-radius curve section, which are beneficial to meeting the requirements of the small-radius curve section on the comprehensive safety performance and the structural universality of the guardrail facility, wherein the small radius is equal to or less than 150 meters and equal to or more than 30 meters.
Background
China belongs to a mountainous country, mountainous areas are large, plains are few, terrain conditions are complex and various, and a small-radius curve line shape is inevitably adopted in a road planning and designing process. Because the small-radius curve section can generate larger centrifugal force to the vehicle, the sight distance of a driver is poorer, the accident that the vehicle collides with the guardrail is easy to happen, the collision angle is often larger, and drivers and passengers are easy to receive extremely strong collision impact force, so that the road guardrail facility is required to have good energy absorption effect and guiding function, and the blocking function is reliable; meanwhile, the linear diversity and the particularity of the small-radius curve road section require good matching and universality when the road guardrail facilities are longitudinally arranged, and the method is applicable to various curve sections.
The guardrail forms commonly used for the expressway at present comprise a corrugated beam guardrail, a concrete guardrail, a cable guardrail and the like. Although the safety protection performance of the existing guardrails meets the application requirements of the general standard section of the highway, the inventor believes that for a small-radius curve section with more unfavorable collision conditions, such as the radius of a curve is less than or equal to 150 meters, the comprehensive safety performance formed by the three aspects of blocking, buffering and guiding of the existing guardrails does not meet the special protection requirements of the section. If the concrete guardrail is used as a rigid guardrail, the concrete guardrail has a good blocking function, but has poor buffering and energy-absorbing effects and a guiding function on vehicles and drivers and passengers collided at large angles in a small-radius path section; the corrugated beam guardrail and the cable guardrail have good buffering function as a partially flexible guardrail, but have poor vehicle blocking function for larger collision energy and limited energy absorption effect, so the existing guardrail facilities cannot be suitable for small-radius curve sections. In addition, a common guidable anti-collision pad at a shunting triangular end of an expressway intercommunicating ramp is a facility with good buffering and energy absorbing effects and a guiding function, but is only suitable for punctiform protection of a certain fixed area on the expressway, and cannot realize the linear protection function of a longitudinal full-length guardrail of a small-radius curve section.
