[0002] Square piers are an important component of bridges. Their reinforcement cages consist of multiple layers of stirrup mesh and several main bars. Traditionally, square pier reinforcement cages are often tied on-site, which is limited by on-site construction procedures and cannot be constructed over large areas. Furthermore, on-site reinforcement is prone to rust, and the stirrup mesh and main bars are often difficult to position, leading to inaccurate positioning. This not only affects the overall size of the reinforcement cage, the spacing between bars, and the thickness of the protective layer, but is also cumbersome to operate and typically requires significant manpower and material resources. Construction efficiency is low, costs are high, and the quality of the square piers is easily affected by the professionalism of the tying personnel. This can easily lead to inconsistent quality, thus impacting the safety of bridges. Utility Model Content
