Problematika budování zařezů při ČPHZ na přeložce komunikace I/38

Abstract

In case of impossibility to observe demanded lengthwise profile during building of thoroughfares by copying of the present grounds it is necessary to build causeways or to exploit cuttings. If the rock of the future cutting of the thoroughfare is classified as a rock with the difficult disintegration we must proceed to breaking the rock by using explosives. If this cutting goes through a build up area exacting character of the project further increases by the necessity for the consideration of civil needs and demands in the neighborhood region. This work concentrates on building of the road from Debř to Mladá Boleslav where the explosives were used both for blasting off the rocks as for the final forming of the demanded slopes.
