ABSTRACT:
The invention relates to a device for determining the position and direction of channel inlets and channel outlets in wastewater systems that, in the horizontal plane, lead into and out of sewer manholes. To this end, a device was created that is provided in the form of a tachymeter attachment which uses a system of mirrors to enable the horizontal aiming beam of the tachymeter to be redirected to a variable depth in order to form a horizontal aiming beam that is parallel to the first. A profiled tube (11) that is attached via a frame (10) to assigned to the tachymeter (1) and reflectors are provided inside said profiled tube (11). The profiled tube is provided with a right angle and passes through the central support (7) equipped with a tubular extension (23), to which an extension consisting of individual tubes (15) that are joined to one another in a telescoping manner is assigned via a coupling (14), and the tachymeter (1), together with the profiled tube (11) and the central support (7), are mounted on the tripod (3) in a manner that enables them to rotate 360°.
