Double waveform guardrail quality testing to analyse the focus of the

2016-10-31

Double waveform beam guardrail quality testing waveform beam guardrail is mainly composed of waveform beam plate, columns, block, end, bracket, fasteners and foundation. Its detection project is mainly divided into five parts: firmness, surface quality, external dimensions, raw material performance and corrosion layer quality. Firmness test. Firmness of the quality of the test method is usually used to feel, mechanical impact to judge. Shake a hand, feel the grain; with a small loader slowly and uniformly push the fence, observe the fence, the foundation are not obvious deformation and cracks, indicating that the solidity of the fence test qualified; on the contrary, observe the fence, the foundation has obvious deformation and cracks, the quality is not qualified!

Sound barriers are mainly used for sound insulation and noise reduction in highways, elevated composite roads, urban light rail underground and other transport and municipal facilities, to control the impact of traffic noise on the nearby urban areas, and can also be used for sound insulation and noise reduction in factories and other noise sources. Want to highlight the advantages in the industry, to obtain a larger share of the market, the need to do in the production and quality of the project to ensure that to do a good job need to meet certain standards. The basic function of the requirements: sound waves in the propagation process, when encountering the sound barrier, it will occur reflection, transmission and bypass three phenomena. Usually the barrier can prevent the propagation of direct sound, and make the transmitted sound have enough attenuation, and the transmitted sound shadow.

Corrugated beam guardrail is not only a simple facility, but also a security guarantee, but also a socialisation of the progress of civilisation. He is in an important role in the degree of this waveform beam guardrail facilities are used in the middle of the highway or the middle of the road for the isolation of vehicles and vehicles, vehicles and pedestrians traffic equipment, the use of waveform guardrail material is generally rigid, that is, the application of steel as a construction material, for rigid structural modelling of the guardrail we will take a certain amount of production technology to make such a guardrail With a certain curved surface, this curved surface will be in the interconnection of the post

1, highway waveform guardrail plate is the main form of semi-steel guardrail, it is a kind of corrugated steel guardrail plate spliced each other and supported by the columns of the continuous structure.　　2, it uses the deformation of the soil base, columns, beams to absorb the collision energy, and force the uncontrolled vehicle to change direction, return to the normal direction of travel, to prevent the vehicle from running out of the road, in order to protect the vehicle and passengers, reduce the damage caused by the accident.　　3, highway waveform guardrail plate steel and flexible, has a strong ability to absorb collision energy, has a good sight-guiding function, can be coordinated with the road line shape, beautiful appearance, can be used in small radius curves, the loss of
