AI Technical Summary

Technical Problem

In the construction of prefabricated bridges, the temporary connection between the cap beam and the pier is difficult to position and connect quickly, resulting in a slow connection speed that cannot meet the needs of rapid construction.

Method used

The structure adopts a combination of positioning plate and threaded sleeve. The positioning plate is inserted into the positioning hole to achieve initial positioning, and the threaded engagement of the fixing screw and the threaded sleeve achieves vertical fastening. Grout is injected and reinforced through the guide pipe and grouting hole.

Benefits of technology

It enables rapid, precise, and stable connection between the cap beam and the pier, improving the efficiency and speed of temporary construction of prefabricated bridges and meeting the needs of rapid construction.
