Abstract: The apparatus (20) is vertically and adjustably placed on the girders (2b) of the sheet piling equipment (1). It has a slab (21) with apertures (26) parallel to the direction of movement. A vibrating beam (60) is vertically and adjustably placed on the slab (21) between two supports (51, 52). Fasteners (28) are arranged on the apertures (26) for the reinforcement rods (22). The (60) beam is lowered by means of prongs (62). The prongs (62) surround the reinforcement rods (22) and ease them into the road surface (6). After lifting the beam (60) with the prongs (62), the slab (21) is moved back and forth horizontally to the apertures (26), then lifted and pulled back up to the equipment (1). Thus, any irregularities caused by installation of reinforcement rods (22) can be eliminated.
