A method and a device for producing and measuring a borehole in the ground is provided, in that the borehole is produced through drilling, that between a carrier unit above a ground surface and a measuring body a measuring rope is tensioned, that the measuring body is inserted so as to fit into the borehole in the ground and lowered, that by means of angle and distance measurements the positions of at least two vertically spaced rope points of the tensioned measuring rope are ascertained and in that on the basis of the ascertained positions of the rope points the position of the measuring body in the borehole is determined as a measure for the location of the borehole.

Method and device for producing and measuring a borehole

A method and arrangement for producing a trench wall element in the ground, in which a trench is produced in the ground through removal of ground material by way of a removal device and a hardening medium is introduced into the trench in order to form the trench wall element. Provision is made in that between the removal device and a carrier device at least two ropes are tensioned, for which the respective positions of at least two vertically spaced rope points of a rope are ascertained through angle and distance measurements by way of a measuring device, and in that the ascertained positions of the rope points are used to determine a location of the removal device in the ground.

Method and arrangement for producing a trench wall element

A method for producing an underwater foundation element in a bed of a body of water, in which a working platform for guiding a drilling tool is lowered to the bed of a body of water, so that a drill-hole is introduced into the bed of a body of water and a pile-shaped underwater foundation element is arranged in the drill-hole and anchored therein. A precise alignment is achieved in that on the pile-shaped underwater foundation element a measuring unit is fixed, through which positional data of the pile-shaped underwater foundation element are determined and in that depending on the determined positional data the position of the underwater foundation element is set by at least one positioning means on the working platform prior to anchoring. The measuring unit is arranged on an adjustment head.
