Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a Y-shaped pier and a construction method thereof. Background Art

[0002] Currently, in large-scale infrastructure construction projects, bridge construction, as an important part, has attracted much attention for its safety, economy and construction efficiency. The formwork of the Y-shaped pier plays a crucial role in bridge construction. The main function of the Y-shaped pier formwork is to ensure that the concrete components can be accurately cast into the designed shape and size. The Y-shaped pier formwork is generally fixed by a tie structure.

[0003] Under the related technology, the tie structure of the Y-shaped pier connects and fixes the two side formworks through multiple sets of tie members (including backing plates, screw rods and nuts) to form a stable support system. The screw rod passes through the inclined leg and connects the two backing plates, and the nut abuts against the backing plate, thereby realizing the clamping and fixing of the formwork.

[0004] In view of the above related technology, due to the differences in the heights of the Y-shaped piers, the existing tie structure is difficult to adjust flexibly, resulting in the inability to effectively meet the construction requirements under various working conditions. This not only increases the construction difficulty, but also may affect the project quality and progress. Therefore, it is particularly necessary to develop a structure that can adapt to Y-shaped piers of different heights. Summary of the Invention
