Drilling device, in particular for producing blast holes in the bed of a body of water and method for inserting an explosive charge into the bed of a body of water |
摘要 |
<p>The device has a working platform (13) fixed at a floating body (10) e.g. floating pontoon. A drilling mast (30) is arranged at the platform. A drilling drive (31) e.g. percussion drive, for drilling rods is mounted at the mast in longitudinal displaced manner. A guide girder (40) e.g. lattice girder, extends in a region beneath the mast and includes a spot drilling guide (41) for the rods beneath the mast. The girder with the spot drilling guide is displaced relative to the mast and the platform in a longitudinal direction of the mast, and is positioned independent of the drilling drive. An independent claim is also included for a method for inserting an explosive charge into the bed of a water body.</p> |
