The method comprises the steps of assembling a number of longitudinal bars 20 and a number of links 22, 24 into a structure having two rows of longitudinal bars, and securing a rigid frame 30 to each of the two rows of longitudinal bars. The frames each have an opening 42 which in use defines the location of the aperture. The longitudinal bars which occupy the opening are cut so as to create the aperture. The frame is intended to maintain the structural integrity of the reinforcing cage despite the cutting of certain of the longitudinal bars. The frame may be rectangular, oblong or oval and may be secured to the longitudinal bars with fillet welds. The frame may further comprise a tube secured inside the opening of the frame and filled with drillable material. The invention also provides a reinforcing cage for the diaphragm wall. |
