Abstract

Translated fromGerman

Verfahren zum Vermessen eines Bohrloches im Boden, das an derBodenoberfläche einen Eintrittspunkt und an seinem unteren Endeeinen Fußpunkt hat, und das mit einem Bohrgestäge erzeugt ist,das oberhalb des Eintrittspunkts einen Einspannpunkt hat, und anseinem vorderen Ende eine Bohrkrone trägt, mittels eines mit demBohrgestänge bis zum Fußpunkt in das Bohrloch eingeführten Inklinometers,bei welchem der Neigungswinkel a des eingeführtenBohrgestänges am Fußpunkt mittels des Inklinometers und dieLänge 1 des freikragenden Bohrgestänges ab Einspannpunkt amBohrgestänge gemessen werden und der horizontale Versatz w desFußpunktes gegenüber dem Einspannpunkt gemäß der freien Biegeliniedes als bei punktförmiger Auflast am freien Ende eingespanntangenommenen Bohrgestänges mit w = 2/3 · 1 · tg α errechnetwird.

Figure 00000001
Method for measuring a borehole in the ground, which has an entry point on the surface of the ground and a base point at its lower end, and which is produced with a drill pipe which has a clamping point above the entry point and carries a drill bit at its front end by means of a with the drill pipe up to the base point of the inclinometer, in which the inclination angle a of the inserted drill pipe at the base point is measured using the inclinometer and the length 1 of the cantilevered drill pipe from the clamping point on the drill pipe and the horizontal offset w of the base point relative to the clamping point according to the free bending line of the drill pipe assumed to be clamped at the free end at point load with w = 2/3 · 1 · tg α is calculated.
