Construction of well Z-18/2 on the wellfield Vinogradi : master's thesis

Cilj ovog diplomskog rada je opis izvedbe i ugradnje zdenca Z-18/2 na crpilištu Vinogradi pored Osijeka, kao i izračun parametara zdenca i vodonosnika. Zdenac Z-18/2 predstavlja zamjenski zdenac - zdencu Z-18 koji je napušten zbog problema u radu. Stalnim praćenjem rada crpilišta utvrđeno je da učinkovitost zdenca tijekom vremena pada. Kako su se ranije na ovoj lokaciji pojavljivali problemi koji su pripisani djelovanju elektrokorozije, pretpostavilo se da bi uzrok tome mogli biti promijenjeni hidrokemijski uvjeti, odnosno kvaliteta vode. Kako bi se izbjegli mogući problemi uvjetovani kvalitetom podzemne vode i nakon analize svih čimbenika koji utječu na vijek trajanja zdenca odlučeno je da se problem pokuša riješiti na dva načina. Prvo je da se dužina sita reducira, a drugo je da se u zdenac ugradi plastična konstrukcija.Abstract: The goal of this thesis is the description of the performance and installation of well Z-18/2 at the wellfield Vinogradi near Osijek, as well as the calculation of the parameters of the well and the aquifer. Well Z-18/2 is a replacement well for the well Z-18 which was abandoned because of problems in work. Constant monitoring of the pumping station was found that the efficiency of the well fall during the time. Earlier, on this location, appear problems that are attributed to electrocorrosion, it was assumed that the cause of this could be changed hydrochemical conditions and water quality. In order to avoid possible problems caused by the quality of groundwater and after analysis of all the factors that affect the life of the well, it was decided to try to solve the problem in two ways. The first is to reduce the length of the sieve, and the second solution is installation of the well-plastic construction
