Abstract
This equipment was developed in an effort to improve the safety and efficiency of the operation of raising the forms for the upstream and downstream faces of dams being constructed by the RCD Method. Regarding the forms themselves, the unit weight of the forms was reduced by employing a truss structure in the vertical ribs, and the efficiency of the form raising operations was improved by enlarging the size of each form panel in order to increase the amount of work completed in raising each panel, On the other hand, the raising machine consists of a form raising device attached to the front of a forklift base machine. Because this form raising device is designed so that the large size dam forms can be securely gripped at three points, the operations of unbolting, raising and bolting the form panels can be performed safely without a danger of swaying. This equipment is presently being employed with good results on the Miyagase Dam Construction Project.
