[0002] Anti-floating anchor rods are a kind of anti-floating measures for underground structures of construction projects. Anti-floating anchor rods are different from general foundation piles and have their own unique properties. The biggest difference between them and general foundation piles is that foundation piles are usually compression piles. The pile body bears the pressure of building loads. The force is transmitted from the top of the pile to the bottom of the pile. The force on the pile body changes with the change of building loads. However, the current foundation pit anti-floating anchor rod structure still has some defects, such as:

[0003] When the existing anti-floating anchor rods are used, when the anti-floating anchor rods are inserted into the ground, the anti-floating anchor rods will easily shake and deviate due to the looseness of the ground, which will make the anti-floating anchor rods easily tilted during insertion and installation, so that the anti-floating anchor rods are less effective during use, making it inconvenient to use the anti-floating anchor rods in construction projects.
