The construction of the replacement well Z-14 in the Vinogradi well field Osijek : master's thesis

Zdenac Z-14 na crpilištu Vinogradi u Osijeku izveden je kao zamjenski zdenac zdenca B-14 nakon što se provjerom stanja zdenca ustanovilo da je došlo do pjeskarenja i vjerojatnog proboja konstrukcije zdenca. Radovi na izvedbi zdenca provedeni su početkom 2021. godine, a izvođač je bio Vodovod – Hidrogeološki radovi d.o.o. Osijek. Zdenac B-14 jedini je zdenac koji do sada nije dobio svoju zamjenu, odnosno bio je u eksploataciji sve do siječnja 2020. godine kada je došlo do pjeskarenja. U ovom diplomskom radu prikazane su osnovne, geološke i hidrogeološke značajke crpilišta Vinogradi i šireg područja, izvedba zdenca Z-14 u koracima i parametri zdenca Z-14 koji su izračunati pomoću podataka pokusnog crpljenja koji se izvodio nakon izvedbe samog zdenca.Well Z-14 at the pumping station Vinogradi in Osijek was constructed as a replacement well B-14 after checking the condition of the well and found that there was sandblasting and probable penetration of the well structure. The works on the construction of the well were carried out at the beginning of 2021, and the contractor was Vodovod - Hidrogeološki radovi d.o.o. Osijek. Well B-14 is the only well that has not received its replacement so far, ie it was in operation until January 2020, when sandblasting took place. This thesis presents the basic, geological and hydrogeological characteristics of the Vinogradi pumping station and the wider area, the design of the Z-14 well in steps and the parameters of the Z-14 well, which were calculated using experimental pumping data performed after the construction of the well
