THE TECHNOLOGIES OF BUILDING PIT CONSTRUCTION

V diplomskem delu bomo opisali tehnologije izdelave gradbenih jam, kot so izdelava pilotne stene, diafragme, zagatne stene, zagatni nasip. Opisani so tudi različni postopki injektiranja in podrobno sidra, saj je njihova prisotnost pri izgradnji varnih gradbenih jam vse večja. Ker se v gradbenih jamah pojavlja tudi talna voda, so razloženi tudi načini, kako zagotoviti, da v jamo ne vdira voda oziroma kako jo odstranimo. V praktičnem primeru pa se bomo predvsem osredotočili, kako zaščititi in zagotoviti vodo nepropustnost za gradbeno jamo II na reki Savi za potrebe izgradnje HE Krško. Predvsem bomo tu prikazali tehnologije zagatnih nasipov, zagatnih sten, injektiranje, črpanje vode, s katerimi zagotovimo varnost ljudi in materialnih dobrin.In the graduation thesis different technologies of constructing building pits are described, such as the construction of pile walls, diaphragm walls, sheet-pile walls, cut-off walls. The different injection methods as well as jet-grouting method and the technology of ground anchors are also presented, since they are becoming an essential part of safe building pit construction. Ground water is another subject considered and described in present thesis. The attempt to explain the ways of stopping and removing ground water is done. In the practical part of the thesis the consideration on how to protect and manage water inaccessibility of the building pit II on the Sava river for the needs of constructing Krško hydroelectric power station. A close look at practical applicability of the technologies of cut-off walls, sheet-pile walls, injections and water pumping, with which we ensure safety of people and material goods, was taken
