[Chinese paint information] these days, careful citizens passing through the Daguan road section of Shangtang road will find a different landscape: the viaduct piers here are quietly changing, The gray concrete pier, which originally showed the natural essence, was painted milky yellow. Looking from a distance, it brightens people's eyes

what's going on? It turned out that Hangzhou municipal facilities Supervision Center was piloting a landscaping demonstration project from Daguan road to Huzhou street of Shangtang viaduct. The whole demonstration section is about 2 kilometers long, and it is expected to be well received by customers by the end of this month

the piers are painted milky yellow, and the citizens are worried about not being able to bear dirt

yesterday, they also went to the scene to have a look. From the Daguan intersection of Shangtang road to the north, there is a touch of yellow in front of you. The lower part of the pier column of the elevated pier is painted gray, while the position of more than two meters and the bottom of the pier are painted milky yellow. Even the downcomer set along the pier column is also painted milky yellow

several citizens were randomly asked, and most of them commented that the visual effect was good. "It looks much more beautiful than before. When I drive by and see this warm color, I feel better."

but some people worry: "it looks pretty. However, under the viaduct, there are many cars and a lot of dust. Over time, will such a light color not be resistant to dirt and will it be difficult to clean at that time?"

in this regard, the relevant staff of the bridge and tunnel section of Hangzhou municipal facilities Supervision Center said that at the beginning, they also considered the problem of cleanliness, so they specially chose environmental friendly and pollution-resistant water-based coatings. "As long as this coating is washed with a high-pressure water gun, it can be cleaned. When it is completed, we will ask the maintenance unit to clean these piers and Bridge bottoms regularly according to the actual situation."

the scheme was announced before construction, and the milky yellow got the highest score

some citizens also proposed that it was a good thing to "beautify" the viaduct by moving the prefix 10 downward and then conducting the tensile test later, but why did they choose milky yellow alone? Next, will the management try other colors to beautify the viaduct in Hangzhou

in this regard, the relevant staff of the bridge and tunnel section of Hangzhou municipal facilities Supervision Center said that before the construction, they had visited Shanghai, Guangzhou and other places, and made a variety of plans to solicit opinions from the public in July last year

"There are four colors, namely yellow, Hai Bao blue, coffee and gray. At that time, we also designed several schemes such as plane and relief for the pier column facade. There are a total of eight schemes for matching the color and facade. Finally, at the time of publicity, more than 60% of citizens chose the scheme of milky yellow + gray plane paint. Therefore, when we finalized the scheme, we finally chose this one according to the opinions of the people The program with the highest score. "

it is understood that in the static strength demand stage (1906-1959), if the pilot effect of the demonstration road section is good, then this beautification project is expected to be popularized in the whole Shangtang viaduct

limit the height of Parthenocissus to avoid affecting the inspection

this Shangtang elevated landscaping demonstration section project also specially takes into account one detail, that is, the growth of Parthenocissus

in the past, the Parthenocissus on Shangtang elevated has been allowed to grow without any restrictions. This time, when the paint is finished, they will also lay a piece on the surface of the pier to let the Parthenocissus grow

"at present, the material of laying has not been determined, but the height will be limited. First, the height limit can make the Parthenocissus grow at a certain height and look more beautiful. Second, it can avoid the Parthenocissus from wrapping the whole pier column and bridge bottom plate, which helps to leave a position for maintenance personnel to repair."

according to the staff of the bridge and tunnel section of Hangzhou municipal facilities supervision center, the main structure of Shangtang viaduct is a concrete continuous beam. Since it was put into use in 2004, it has been in service for more than 8 years and has not been beautified before. "This time, when painting the base, we will repair the shrinkage cracks of the pier."
