Barrier system.
Background technology
In recent years, China's level of infrastructure development is continuously improved, and domestic expressway construction level is constantly progressive, and close
Living standards of the people are continuously improved over year, and vehicle guaranteeding organic quantity rises year by year, and traffic accident is caused to take place frequently, people's lives and properties peace
It is on the hazard entirely, therefore the demand to traffic safety is constantly promoted, in addition to the demand of the national communication regulation education of constantly improve,
It is also embodied in the security requirement of highway auxiliary facility.Therefore, the following demand to road guard will be continuously increased.But due to
China's the relevant technologies are had a poor foundation, starting evening, and less than 10 years, product standard was promulgated only 5 or six years for production and usage time, country's mark
Standard promulgates that each production unit requires performance, the technical parameter index of road safety barrier, the technological process of production is grasped only 2 years
It is different, cause the quality of this product very different.The guardrail that part way is dealt with improperly as a result of anticorrosion process
Product, or even within one or two year, guardrail has just had rusty stains, and not only affects the visual effect of highway, also significantly
The Acceptable life for shortening guardrail, increases maintenance cost；Part guardrail is due to design defect, protecting against shock energy force difference, shield
Column does not play due protective action, and accident vehicle is caused to break through guardrail, is detached from highway, leads to the tragedy of car crash；Portion
Divide guardrail due to structural member mounting means, poor reliability meets strong wind weather and guardrail loosening even lodging phenomenon occurs.Simultaneously
There are the prior arts when installing guardrail tedious process, long construction period, occupies and consumes excessive manpower and material resources
Etc. problems, divider current spininess security consideration is designed, it is less from the aspect of noise insulation, it is only most to hand over
Resident near logical thoroughfare is influenced by noise pollution deeply.The present invention provides a kind of new technical solution, can be good at solving
The above problem.
