Apply this, the surface of the bridge is like "lotus leaves" and it is not easy to be stained

There are many rivers and lakes in Wuhan, and urban transportation facilities have developed rapidly. At present, there are 803 urban bridges and tunnels in the city. It has become a major characteristic of the city. How to keep them "best" through operation and maintenance management? The reporter from the Yangtze River Daily learned from the Daoqiao Center of the Wuhan Urban Management Law Enforcement Committee that the current urban bridge tunnel maintenance period has technical standards.

The surface of the bridge and tunnel facilities due to the erosion of wind and rain and the adhesion of various pollutants, which seriously affects the quality of bridge and tunnel facilities, also accelerate the deterioration and corrosion of the facility, affects the safety of the bridge and tunnel structure and the service life. "Trouble", it takes a lot of manpower and financial resources every year to regularly clean and remove the bridge and tunnel facilities in Wuhan, but the results are not good.

According to the requirements of urban refined management, the Daoqiao Center has worked hard to seek new materials and new processes. Under the guidance of the Municipal Urban Management Law Enforcement Commission, the Daoda Bridge Center passed multi -party research, multi -scenario trials, multiple technical demonstrations, third -party experts on the spot. The review, the use of new hydrophobic protective coatings completely solved the problem.

Recently, a reporter from the Yangtze River Daily followed the staff of the Daofei Bridge Center to investigate at the viaduct of Xudong Street. The person in charge of the coating construction introduced: "This elevated just painted a new type of hydrophobic protection coating, the surface of the bridge is like 'lotus leaf'. The dirt is very easy to slide with the water. "He also demonstrated on the spot. He splashed a bottle of mud water on the railings and simulated the bridge stains formed by the water or area of ​​the road area. A small amount of mud water is attached to the railing, wiped it gently with a rag, and the railing becomes clean. It is reported that this new process is currently implemented on the 40 bridges and tunnels in the city, achieving the effect of improving the appearance quality and cost of urban maintenance.

Luo Jun, chief engineer of the Daqiao Center, introduced that this year, in response to the prevention and anti -corrosion work of bridges in Wuhan City, the Daoqiao Center has planned the preliminary draft of the "Technical Regulations for the Prevention and dustproof and dustproof and dust -proof of the Urban Bridge Tunnel in Wuhan City".

"Bridge management must be refined, and regulations must be continuously improved. Wuhan City has formulated multiple local standard specification processes in applications such as new materials, new processes, and new equipment." Luo Jun introduced that in 2017, our city issued "Wuhan Wuhan The Regulations on the Safety Management of Municipal Urban Bridge Tunnels "put forward clear standards for the construction of transfer, safe use, and inspection and maintenance management; in 2019, the" Technical Regulations for the Maintenance of Bridge Tunnels for Bridge Tunnel "was introduced to realize the refinement management of urban bridge tunnels in a targeted manner. Requirements; in 2020, the "Technical Regulations for Bridge Tunnel Health Inspection" was introduced, which clarified the unified technical standards for 20 cities and district -level management units in Wuhan.

According to the relevant person in charge of the Daqiao Center, the preparation of management standards for management and construction standards is the real requirements of China's urban management system reform, and it has also become a standardized and technical theoretical support for the refined management of urban cities.
