摘要: A method of preparing parallel-wire cable for use in prestressed concrete pressure tanks comprises the steps of cutting the cable in lengths with each wire of equal length, twisting the lengths of cable at least twice about the longitudinal axis of the cable, and preferably from two to five times, and positioning the lengths of cable within the tank wall prior to stressing the cable. The cable is preferably twisted before it is placed in position in the tank. However, it may be twisted after insertion into passageways within the concrete wall of the tank.
