The inner transformation of 2000 new LED Street 1834 Street viaduct

20 years of service of the inner ring elevated road started street reconstruction, Shanghai urban construction group in Luqiao Nanpu bridge approach Puxi segment to Zhoujiazui road about 29 kilometers between the viaduct on the replacement of lamps and lamp posts, including parts of the base, a total of 1834 sets of lights. The new LED will use energy-saving light source lamp. Is expected to replace all the end to more than a year.

Traffic across the board since December 1994, after nearly 20 years of operation, the elevated 10 meters single fork Steel Street has shown varying degrees of weakness or even "disease". According to the previous investigation, the existence of inner ring pole surface due to oxidation and rusting, the lamp transmission cover because of aging caused light transmittance decreased, reduce oxidative discoloration, lamp reflector surface reflection properties, not only affect the level of road lighting, but also a waste of lighting electricity. At the same time, between the base part of the street lamps and the lamp post and the lower end of the foundation bolt and nut connections such as aging, corrosion or damage, resulting in individual security risks overturning the collapse of the street.

The new lights will use has the characteristics of low power consumption, high luminous efficiency, long service life of the LED light source and lighting energy saving, energy saving efficiency can reach 50%. The new pole replacement will be able to achieve 12 level wind impact resistance.

The reporter saw in the inner ring Hutai Road to Wuning Road, because the construction is only allowed in at midnight to 5 a.m. this period of time, in order to avoid the influence of noise, the application of the "anti wall construction work integrated portable device" patent in this construction, the device is shaped like a box. Construction personnel in the inside of the box operation, can greatly reduce the noise. Install only 15 minutes, does not occupy the lane.
