Technical Field

[0001] This utility model relates to the field of highway bridge construction technology, specifically a prestressed anchorage suitable for highway bridge construction. Background Technology

[0002] Prestressed anchorages are a type of anchorage used in engineering construction for the prestressing tensioning of concrete. They are commonly used in bridge construction. They are pre-installed and positioned before concrete is poured, and the anchorages are embedded at both ends of the concrete, which are the two ends of the corrugated pipe. These anchorages are designed to provide stability for the jacks during tensioning.

[0003] During use, the components are assembled sequentially, including the spiral reinforcement being fitted onto the anchor seat. However, this is not fixed in place, posing a risk of wobbling during use. To increase the stability of the spiral reinforcement installation, we propose a prestressed anchorage suitable for highway bridge construction to address the aforementioned problems.
