Description

Technical Field

[0001] The utility model relates to the technical field of anchor rods, in particular to an umbrella-shaped cage core bag enlarged head anti-floating anchor rod. Background Art

[0002] Anchor rods are fixed in foundations or rocks to provide stable support for buildings, bridges or other structures, preventing the structure from moving or tilting due to loose or unstable foundations. Anchor rods can effectively withstand tensile forces and disperse these forces to deeper strata, thereby improving the tensile resistance of the structure and reducing the risk of damage caused by external tensile forces. Anchor rods can be selected from different materials and specifications according to specific engineering requirements, adapt to different geological conditions and engineering environments, and have strong flexibility and adaptability. Anchor rods play an important role in engineering construction, not only providing structural support and stability, but also improving the safety and durability of the structure. They are a key component to ensure the safe operation of engineering structures.

[0003] The existing anchor rod has a small force-bearing area on one end of the surface, but is affected by water flow, surge or other liquid dynamics. The small force-bearing area will reduce the friction or fixing force between the anchor rod and the surrounding soil or rock, which may cause the fixing effect of the anchor rod to be unstable or weak. The small force-bearing area will increase the stress concentration on the surface of the anchor rod, which may easily cause fatigue damage or damage to the anchor rod material and shorten its service life. Water flow, surge or other liquid dynamics will cause impact and pressure on the surface of the anchor rod, increase the vibration and movement risk of the structure, and may affect the stability and safety of the structure. The anchor rod is easily affected by environmental erosion and damage, which increases the cost and workload of subsequent maintenance and repair. Utility Model Content
