Abstract

Method and apparatus for drilling dewatering holes into the lower surface of a concrete hollow-core slab (5). The apparatus comprises at least two drills (10) connected with a slab lifting crane. The drills (10) are attached to a detachable beam (9), and the apparatus is provided with at least two interchangeable beams with different mutual distances between the drills. The beam (9) is fastened to the apparatus by means of a quick-release fastener. <IMAGE>
