Abstract (en)
[origin: EP0568498A1] For making holes with an undercut in concrete plates, a movable apparatus is available. A bending arm (14, 15) is fastened in an articulated manner on a motor vehicle (1). A drilling device (20) or an undercutting device can alternatively be fastened on the front end of the bending arm. By displacing the bending arm, a number of holes at a distance from one another can be made in a concrete slab (9) with the same position of the motor vehicle (1). After the undercut holes (28) have been filled with a hardening mass, vertical positional stabilising of adjacent concrete plates is achieved. <IMAGE>
