Abstract

Verfahren zum Vermessen eines Bohrloches im Boden, das an der Bodenoberfläche einen Eintrittspunkt und an seinem unteren Ende einen Fußpunkt hat, und das mit einem Bohrgestäge erzeugt ist, das oberhalb des Eintrittspunkts einen Einspannpunkt hat, und an seinem vorderen Ende eine Bohrkrone trägt, mittels eines mit dem Bohrgestänge bis zum Fußpunkt in das Bohrloch eingeführten Inklinometers, bei welchem der Neigungswinkel a des eingeführten Bohrgestänges am Fußpunkt mittels des Inklinometers und die Länge 1 des freikragenden Bohrgestänges ab Einspannpunkt am Bohrgestänge gemessen werden und der horizontale Versatz w des Fußpunktes gegenüber dem Einspannpunkt gemäß der freien Biegelinie des als bei punktförmiger Auflast am freien Ende eingespannt angenommenen Bohrgestänges mit w = 2/3 · 1 · tg α errechnet wird. A method of surveying a borehole in the ground, the one entry point and has a base point on the bottom surface at its lower end, and that is produced with a Bohrgestäge having a clamping point above the entry point, and carries a drill bit at its front end, by means of a introduced by the drill string to the base point in the borehole inclinometer, wherein the angle of inclination a of the inserted drill pipe at the base by means of the inclinometer and the length 1 of the cantilever drill string from the clamping point to be measured on the drill string and the horizontal offset w of the foot in relation to the clamping point of the free bend line of the drill string clamped as Compressive load at point-shaped at the free end adopted with w = 2/3 · 1 · tg α is calculated.
