Road doctor "Ying Da conservation G314" construction of Sino Pakistani economic corridor"
In August, in the south of the Tianshan Mountains, the northern edge of the Taklimakan Desert, here on the G314 highway, Ying Da thermal recycling units are working hard.
G314 is a starting point for Xinjiang, Urumqi, Pakistan China border end point Khunjerab Port Road, the highway from Kashi to Khunjerab port is also called Pakistan friendship highway, the Karakoram Highway, is to "provide important transportation support Pakistan Economic Corridor construction. Prior to the high-speed opening of the G3012 line in parallel with it, G314 was the only trunk highway to Kashi from Urumqi, and still carries part of the freight and passenger missions from Akesu to Kashi.
Because of the special geographical location, to "road doctor" Ying Da also brings unprecedented problems: here every afternoon at 3-4, the vast Gobi will be blowing sandstorms, the wind reached 6-7. The wind also accelerated the loss of heat on the road, and brought new problems to the work.
In view of this situation, they immediately set to the side with the windshield, and HM18 high voltage pulse heating machine Ying Da multidimensional innovation may be old material temperature increase above 20 degrees, ensure the recycled mixture paving temperature not lower than 140 DEG C.
This construction is another important feature is the Calvert, a total of 46 seats, 46 seats and take an important role in flood discharge. And the bridge maintenance, Ying Da thermal regeneration unit can also easily cope with: patent rake loose technology, to eliminate the milling pavement road resonance hidden trouble; unit equipment is not overweight, does not affect the bridge structure.
In Gobi, the species and quantity of plants and animals are low, the growth cycle is long and the food chain is very simple. These characteristics determine that the ecological environment will be difficult to recover once the ecological environment has been destroyed.
After calculation, because Ying Da thermal regeneration technology to achieve the original pavement 100% recycled, this construction can reduce 17856 tons of waste emissions; while saving 11160 tons of new asphalt mixture, avoid the quarry to bring environmental destruction.
Harsh natural environment, construction workers brought unimaginable hardships. But this did not stop the project staff on the project quality diligently pursue, their organization, scientific construction carefully, the successful completion of the construction tasks.
Ying Da's thermal regeneration unit is tenacious, excellent quality, able to withstand all kinds of harsh natural environment, and the staff of the dedication without regret is worthy of praise.
