| Abstract [eng] |
Water supply installation technologies are analyzed in Master‘s thesis. Investigated object – preproject water supply installation methods, when 100 m water supply path must be equipped under asphalt covering with pipes – diameter 110 mm Covering construction class III: top layer of asphalt – 4 cm; lower layer of asphalt – 4 cm; base layer of asphalt – 10 cm; base of rubble layer – 15 cm; sand layer – 33 cm. In introductory section work relevance is characterized; investigated object, aim of investigatory, tasks, the practical value of the results and work structure are described. In first work section water supply development history is reviewed, and water supply relevance in Lithuania and foreign countries, engineering networks. In second section different water supply networks installation, reconstruction technologies and pipeline alternatives are analyzed. In third work section preproject water supply installation evaluation is prepared. Analysis is made with SAW method for different water supply installation technologies, most effective technology is established for pipeline instalation under asphalt covering. In final section of Master‘s thesis received results of calculations are summarized and conclusions are formulated. When preparing Master‘s thesis newest scientific, technical literature was used, requirements for construcion technical regulations where considered. In this Master‘s thesis most attention is meant for Lithuanian water supply, modern instalation of sewage networks, technologies of reconstruction and their operation. Due to the need to reconstruct, expand water supply and sewery networks with newest material technologies. To reduce inconveniences for residents during work performances, to finish job quickly, do not damage enviroment and landscape, also do not damage ecological balance. |
