20.500.12556/RUL-187817 Primerjalna analiza bele in črne kadi diplomska naloga Comparative analysis of white and black tank systems Diplomska naloga obravnava primerjalno analizo sistemov bele in črne kadi pri izvedbi podzemnega rezervoarja za vodo. Namen naloge je predstaviti konstrukcijske in tehnološke značilnosti obeh sistemov hidroizolacije ter primerjati njuno izvedbo z vidika vodotesnosti, trajnosti, zahtevnosti gradnje in ekonomskih vidikov. Teoretični del opisuje principe delovanja bele in črne kadi, uporabljene materiale, zahteve za projektiranje ter izvedbo posameznih delovnih in dilatacijskih stikov. Praktični del temelji na primeru podzemnega rezervoarja v okviru projekta visokoregalnega skladišča VRS K. ETRA, pri katerem je izvedena primerjava obeh tehnologij. Analiza stroškov temelji na enaki geometriji konstrukcije ter primerljivih količinah izkopa, betona in armature, pri čemer se razlike pojavijo predvsem zaradi različnega načina zagotavljanja vodotesnosti. Rezultati kažejo, da sistem bele kadi zahteva kakovostnejši vodoneprepustni beton ter natančnejšo izvedbo delovnih stikov, medtem ko črna kad temelji na izvedbi zunanje hidroizolacijske membrane. Kljub nekoliko višjim stroškom posameznih elementov bele kadi je primerjalna analiza pokazala, da je bila pri obravnavanem objektu izvedba črne kadi zaradi dodatnih hidroizolacijskih del in zaščitnih slojev približno 3,0 % dražja. Ugotovitve naloge predstavljajo uporabno izhodišče za izbiro ustreznega sistema hidroizolacije pri načrtovanju podobnih podzemnih objektov. This bachelor's thesis presents a comparative analysis of the white tank and black tank waterproofing systems used in the construction of an underground water reservoir. The aim of the thesis is to present the structural and technological characteristics of both waterproofing systems and compare their performance in terms of watertightness, durability, construction complexity, and economic aspects. The theoretical part describes the operating principles of both systems, the materials used, design requirements, and the execution of construction and expansion joints. The practical part is based on a case study of an underground reservoir designed for the VRS K. ETRA high-bay warehouse project, where both construction technologies are compared. The cost analysis assumes identical structural geometry and comparable quantities of excavation, concrete, and reinforcement, with differences arising primarily from the different approaches to achieving watertightness. The results show that the white tank system requires high-quality watertight concrete and more precise execution of construction joints, whereas the black tank system relies on an external waterproofing membrane. Although some individual components of the white tank are more expensive, the comparative analysis showed that, for the case study considered, the construction of the black tank was approximately 3,0 % more expensive due to the additional waterproofing works and protective layers. The findings provide a useful basis for selecting an appropriate waterproofing system in the design of similar underground structures. diplomske naloge gradbeništvo bela kad črna kad hidroizolacija podzemni rezervoar za vodo vodotesnost vodoneprepustni beton delovni in dilatacijski stiki graduation thesis civil engineering white tank black tank waterproofing underground water reservoir watertightness watertight concrete construction and expansion joints true false false [Ž.
