Key Technology of Prefabrication Construction of Portal Pier Bent Caps with Large Cantilever
In order to ensure the smooth flow of municipal roads and avoid a large number of demolition and renovation operations, the substructure of the Rama III to Outer Bangkok West Ring Expressway project is designed as a cap beam of portal pier, and the construction adopts the fully-suspended short-line combination method, in which two spans are equipped with large cantilever structures. For portal pier with large cantilever structure, the construction technology of “prefabricated U shell+fully suspended segment assembly + internal cast-in place” is adopted by comparative study. The application results show that this method can realize the construction of portal pier with large cantilever cap beam under complex municipal conditions, and has the advantages of short construction period, small traffic interference and high safety.
