The subject of this thesis is the execution construction pit for multi-storey car-park building in\ud
Ljubljana. The supporting structure was made with high pressure grouting (e.q jet grouting),\ud
and anchored with temporary ground anchors in one or two levels. An overview of jet\ud
grouting and temporary ground anchors procedures accoding to current standards is shown.\ud
A special attention is put on the currently valid execution of works in our country. We\ud
primarily examined the problems occurring due to the deviation from technical regulations or\ud
inability to stick to them, which may be the consequence of either old equipment or sticking\ud
to generally accepted procedures of the execution, as well as requirements for a cheaper\ud
execution.\ud
The thesis presents the description of experiences gained during the execution works, the\ud
results of control examinations, the problems that occurred during the execution and\ud
appropriate solutions. In the phase of the jet-grouting-piles execution, which were used as a\ud
supporting structure, the attention was on the technology of the single fluid system and its\ud
effectiveness in the ground, while with ground anchors the most attention was paid to ground\ud
anchor installation and.\ud
The problems occurring on the construction site are often result of an incomplete project\ud
documentation, often involving the old and incomplete documentation of neighbouring\ud
buildings. The solution of issues in relation to the unexpected ground conditions, which\ud
significantly delayed the execution of works, is examined
