Sažetak
At planning and executing the construction pit excavations in alluvial soil layers, we are very often confronted with undergorund water problem, which level could be considerably higher than planned excavation depth. Consequently there is a problem of pit walls stability, sealing of pit lateral sides as well as pit bottoms sealing. At solving first two problems, tehre is a number of technical procedures, more or less of standard use. At pit botttom sealing, we are facing problems which can be extremely complex, but range of possible sollutions is very poor. Cases with impermeable soil layers of suffficiant thickness at relatively reachable depth under pit bottom, are more and more seldom - it can almost be considered that such locations are alreay used up. One of possible solutions for pit bottom sealing is application of jet grouting method. This sollution is very flexible and works are mostly under controll, which is wiht other methods very often not the case. Some of the solutions used for numerous excavation pit sealings in various hydro- technical constructions executed during past several years would be shown in the Paper. Also, the problem of the controll investigaton of executed works quality will be worked out in the Paper.
