What are the daily cleaning and maintenance methods for cable-stayed bridges, tunnels, steel box bridges, and road-rail bridges?
1. Use bridge shot blasting machine
The bridge deck shot blasting machine is a small mobile shot blasting machine produced by our machinery for the cleaning and maintenance of various bridge decks and bridges. So what is the role of the bridge deck shot blasting machine?
1. The bridge deck shot blasting machine can clean up the floating slurry and impurities on the concrete surface;
2. Improve the friction of the bridge section and increase the anti-skid performance;
3. Make the surface of the bridge deck concrete rough and uniform, so that the base layer and the bottom mortar have a better bond;
4. After the construction of the bridge deck shot blasting machine, the defects of the concrete can be exposed in advance and the pores of the concrete can be opened.
The working principle of the bridge shot blasting machine:
The bridge shot blasting machine produced by our machinery uses a motor-driven shot blasting wheel to generate centrifugal force during high-speed rotation. Under the action of the centrifugal force, the steel shot is thrown out of the directional sleeve and impacts the concrete surface of the bridge deck to clean and strengthen. effect. Then the steel shot, dust and impurities come to the top of the storage hopper through the wind force and rebound effect of the dust collector. The pellets are separated on the silo, the pellets enter the storage hopper for continued use, and the dust enters the dust collector through the connecting pipe to complete the cycle work. Now bridge deck cleaning and maintenance basically rely on bridge deck shot blasting machines for construction.
2. Use chiseling equipment or milling equipment
The chipping machine and milling machine can also play the role of cleaning the bridge deck. However, due to the high labor intensity, the flatness of the original bridge deck is destroyed, the surface is uneven, and the environmental dust pollution is serious. Used to clean up the bumps and corners of some bridge decks.
With the rise of China’s economy and the development of society, cable-stayed bridges, tunnels, steel box bridges, and road-rail bridges are increasingly being built on daily bridge decks, and follow-up cleaning and maintenance work is heavy.
