The invention relates to a method for adjusting the position of a precast concrete slab (1), in particular to the support pillar for a carriage way for high-speed transport means. The inventive slab (1) is supported by a foundation consisting of a sub-layer made of a hardenable material and a base bearing layer (5) of the foundation and is brought into a predetermined position prior to the sub-layer arrangement with the aid of several vertical bars (11) which are used as auxiliary adjusting elements (4, 4'). The inventive method is characterised in that at least two vertical bars (11) rest against a bearing block (13) which is disposed on the bearing layer (5) and displaceable in a longitudinal and/or transversal direction of the slab (1). Said invention makes it possible to arrange the appropriate auxiliary adjusting means and a corresponding precast slab.
