    Bearing constructions applied for drilling boreholes with rigs are most commonly frame structures consisting of rigs or drilling masts. Their main bearing elements - shears - are deposited on foundation beams in the foundation plates in the ground or the subbase. In such a system the subbase is a basis for the rig and mast. The height of such a construction in the form of a cubicoid framework enables assemblying devices protecting the drilling well's outlet. In operating conditions, the structure undergoes numerous loads, frequently exceeding those in the rig and mast. Hence much attention is paid to the construction of subbases as it is a guarantee of safe operation of the rig.
