For the installation of outdoor large-scale LED advertising screen, the base and support materials are generally steel structure. However, due to the influence of temperature and humidity, it will still cause corrosion. In order to ensure the safety performance of LED screen, it must be reinforced in time. So what are the methods of strengthening outdoor full-color LED screen?Large outdoor LED advertising screen 1. Foundation expansion method: by setting concrete enclosure or reinforced concrete enclosure, increase the area of the bottom foundation of outdoor LED billboard, and change the uneven settlement of foundation caused by the small bottom area and insufficient bearing capacity of billboard foundation.
2. Pit underpinning method: directly dig a pit under the underpinned foundation and pour concrete.
3. Pile underpinning method: static pressure column, driven pile, cast-in-place pile and other piles are set at the bottom or both sides of the billboard foundation to reinforce the foundation.
4. Grouting underpinning method: the chemical slurry is evenly injected into the foundation, through which the original loose soil or cracks are cemented and solidified, so as to improve the foundation bearing capacity, waterproof and impermeability.
