waveform beam and high speedGuardrail plateReuse analysis

(1) waveform beam and high speedGuardrail plateReuse analysis. & quot; 8 "glyph median wave beam at high speedGuardrail plate. Taking advantage of theHighway guardrail plateSuperiority of original column and column grave. Remove the prevention blocks used for roadside waveform under the beamHighway guardrail plate, median and chain link fence of wave beam Mosaic "8" glyph highway guardrail plate beam, so the original median waveform girder highway guardrail plate got 100% of the use of components. Special sections transformation highway guardrail plate also USES the original highway guardrail plate column and the stop block. (2) waveform girder highway guardrail plate reuse construction transportation analysis. If new waveform girder highway guardrail plate need to will the old highway guardrail plate disassembly, column due to years of buried in underground, has been difficult to pull out, usually can only adopt the method of gas welding cut, wasted highway guardrail plate column material. Old highway guardrail plate need to be away, then new high-speed guardrail plate into space, to pile driving, high-speed guardrail plate installation. Need welding and piling machinery in construction process, and transport waste energy repeatedly, long construction period. 648 "glyph central beam high-speed guardrail waveform transform highway guardrail plate plate and the special section, the use of the original post, the pipe casing can be set in the original post. On the other side outline of wave beam will only move to the median and high-speed guardrail board together with the original" 8 "glyph highway guardrail plate beam, which can greatly reduce the construction transport distance. (3) the waveform girder highway guardrail board recycling economic analysis. 118" glyph central highway guardrail waveform beam plate, improve the protection ability. To tear down the old highway guardrail plate, the newly built highway guardrail waveform beam plate solution, compared to 169200 yuan per km to save, save 78% of the cost, protective capacity increased by 32%, protection grade A level 93 kj, guang shao expressway practical application of the 76 km, the project research results directly to save material cost $2.54 million, save 21% of the cost of raw materials. At the same time, reduced the removal of the old highway guardrail plate, installation, transportation construction cost of the new high-speed guardrail board and oil consumption. And reduces the construction impact on the speed of traffic and traffic. This project makes full use of the original highway guardrail plate material, and makes high-speed guardrail plate after transforming protective capacity up to 93 kj the rules and regulations of the protective ability. According to the investigation and analysis, accident death has become China's men and public accident harm the first cause of chain link fence www.jtwiremesh.com. According to the ministry of public security report our country road traffic accident statistic analysis, scientific and reasonable traffic safety facilities, about 17% can effectively reduce the traffic accident death toll, because of the traffic accidents in China in 2006 killed 89400 people, to reduce the deaths of 15000 people.
