[0002] Anti-floating anchor rods are a type of anti-floating measure for underground structures in construction projects. They are mainly used to resist the upward displacement of buildings above them. Their function is closely related to the height and changes of groundwater levels. Unlike general foundation piles, anti-floating anchor rods are mainly pull-out piles that bear tension. The anti-floating anchor rod structure is deep into the stratum, one end is connected to the engineering structure, and the other end is deep into the stratum. In actual application, after the construction of the anti-floating anchor rod is completed, it often takes a month or even longer to complete the construction of the foundation concrete, causing the exposed steel bars of the anti-floating anchor rod to rust. The rusted anchor rods not only require rust removal, which increases labor costs, but if the rust removal is not thorough, it will affect the bonding strength between the anti-floating anchor rod and the foundation bottom plate concrete, and will also affect the anti-floating effect. Therefore, it is particularly important to develop anti-floating anchor rods with anti-rust protection devices. The anti-rust protection device and installation method mainly involve setting a protective layer on the exposed part of the anti-floating anchor rod to prevent the steel bars from rusting. The development and application of this technology are of great significance for improving the anti-rust performance of the anti-floating anchor rod, extending its service life, and ensuring the anti-floating effect.
