| Highway traffic safety facilities,as an indispensable infrastructure for expressways,play a very important role in highway traffic safety,and the most important thing is to ensure the safety of people".Under the premise of people-oriented,combined with the specific circumstances of the highway and social benefits and economic benefits of design and construction,in order to make traffic safety facilities give full play to its function and role.This paper studies the present situation of the highway traffic safety facilities at home and abroad,analyzed and summarized the various items of the highway traffic safety facilities(including highway guardrail,traffic sign,isolation facilities,anti dazzle facilities etc.)the basic functions and classification,and on this basis,this paper summarized the theoretical system of the design and construction of highway traffic signs,marking,guardrail,isolation facilities,anti dazzle facilities setting principle,material selection,type selection,technical requirements,design scheme and construction scheme of traffic safety facilities.According to our current design,highway traffic safety facilities construction,an important node in Zhangjiagang port project in expressway engineering project as an example: Chenyang interoperability,set requirements and construction scheme were studied in detail and expounds on the traffic safety facilities,including the research and elaboration of traffic sign,guardrail,isolation facilities,anti dazzle facilities setting principles,type selection of materials and design requirements,technical requirements,detailed system of quality control points of design,construction and technical scheme,methods and measures,construction process,engineering and corresponding control measures. |
