Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of traffic safety protection, especially relates to a corrugated board combined concrete temporary guardrail structure. BACKGROUND

[0002] In recent years, the highway construction in China develops rapidly, and the completion and operation of the highway greatly facilitate the travel of the masses and the economic development of the places along the way. But with the rapid growth of China's economy and the vigorous development of highway transportation, the traffic volume grows rapidly, which directly leads to the increase of the use frequency and load of highway traffic facilities, and many early built highways have been unable to adapt to the current traffic volume operation demand. According to incomplete statistics, among the highways built before 2004, about 40,000 kilometers have entered the reconstruction and expansion stage. For the reconstruction and expansion of the highway, the mode of operation on one side and construction on the other side is mostly adopted, and the temporary guardrail becomes an important means to protect the construction area. At present, the temporary guardrail is reflected in the convenience of disassembly and assembly, but the design of the anti-collision performance is rarely considered, so accidents in the construction area also occur from time to time.

[0003] The corrugated beam guardrail is a common protection form of highway subgrade guardrail in China, which has the advantages of easy installation and reasonable cost, but the old corrugated beam guardrail structure of most road sections has been unable to meet the protection demand under the current traffic characteristics, and needs to be strengthened. If the original double-wave beam guardrail is completely abandoned, the demolition and abandonment will cause great material waste. The technology of recycling the materials of the original guardrail meets the requirements of safety, environmental protection and economy.

[0004] The concrete guardrail is one of the common highway guardrail forms, which has the advantage of large rigidity through years of application and practice, has a large safety protection margin, and through the continuous research of the traffic safety research units, the structure is prefabricated and processed in the factory, and the standard section is assembled on site through longitudinal connecting components, but the longitudinal assembly is relatively complex, and the longitudinal overall connectivity is weak, which is generally an anchoring type foundation, and cannot meet the function of convenient disassembly and assembly of the temporary guardrail.

[0005] Through the above analysis, it can be known that the temporary guardrail at present has problems such as insufficient protection performance and inconvenient disassembly and assembly, the inventor proposes a corrugated board combined concrete temporary guardrail structure based on the stress mechanism of the concrete guardrail wall and the easy disassembly and assembly characteristics of the corrugated beam guardrail, which regards the corrugated beam guardrail as a longitudinal assembly component, meets the protection ability of the temporary guardrail while being economic and environmentally friendly, and realizes the application demand of the concrete temporary guardrail.
