In recent years, because the strength of steel is higher than other common engineering materials, the main support structure of outdoor billboards is usually based on steel materials. However, in the open air environment, the steel material is easily oxidized and caused by rust due to factors such as temperature, humidity and harmful substances. Severe rust can greatly reduce the load resistance of the steel members. Therefore, we need to Billboard repair reinforcement. The following tree advertising technology consultants will briefly introduce the methods of outdoor billboard repair and reinforcement.
1. Foundation expansion method: By setting the concrete envelope or reinforced concrete enclosure, increase the area of the base of the bottom of the LED billboard, and change the uneven settlement of the foundation caused by the small base area of the billboard and the insufficient bearing capacity.
2. Pit-type underpinning method: concrete is poured directly after digging a pit under the basis of being replaced.
3. Pile type underpinning method: a method of foundation reinforcement is provided by placing static pressure columns, driving piles, pouring piles and the like on the lower or both sides of the billboard foundation.
4. Grouting and underpinning method: the chemical slurry is evenly injected into the foundation, and the loose soil or crack is cemented and solidified by the slurry to improve the foundation bearing capacity and waterproof and impermeability.
