Erection of Pearl Bridge by Bear Angle Vertical Swivel Method
Bear Angle Vertical Swivel Method for arch bridge has been developed for many years overseas and obtained stated success such as Kobaru Valley Bridge in Japan and ArgenLobel bridge in Germany, this method is in the researching period right now in China. During the processing of construction, concrete of arch rib was casted vertically and then rotated, main arch ring was casted vertically by formwork climbing technology, main arch ring was laid to completed bridge elevation by using continues jacks, forming a set of swivel construction method for arch bridge.
