Rear bottom anchors usually cooperate with concrete base to carry the weight and load of the machine, the purpose is to ensure the smooth and normal operation of the machine. The anchor bolts used in concrete structures can be made of carbon steel, stainless steel or alloy steel, and the corresponding varieties should be selected according to different environmental conditions and durability requirements.
When the concrete base is used, weathering, severe cracking and non-compactness will occur, resulting in the loosening of the fixed anchor bolts, resulting in increased vibration of mechanical parts and affecting the normal operation of machine parts. Repairs using traditional methods will result in increased downtime and huge financial losses. In view of the loosening and failure of the bolt, polymer composite materials are the most effective repair methods abroad. The most mature concrete repair material introduced in my country is the American Megawa concrete repair material.
The impact strength and compressive strength of the material itself are far greater than those of concrete materials, and it has the performance of resisting various chemical media. Its excellent adhesion to concrete is greater than its own strength, and it can also adhere to rough surfaces such as steel, and its fast curing performance can save the loss caused by the shutdown of enterprises
