Multipart geodesic levelling board - consists of modular elements with each forming coloured measuring tape

摘要

Several of the modular elements of the levelling board can be combined to form a group which is pushed into another group of modular elements. The modular elements within a group are connected fast to one another by glueing or welding. The lower group of elements can have a point to enable the board to be driven into the ground. This lower group of elements can consist of plastic and can have inserted in it a steel tip for driving into the ground. Between two modular elements a circular horizontal spirit level can be inserted for fixing the vertical position of the board.
