Baigiamajame darbe pateikiama Jurbarko miesto, Vydūno gatvės vandentiekio ir nuotekų surinkimo tinklų vamzdynų būklės analizė. Tyrimų pradžioje vandentiekio ketinių vamzdžių linija (160 m ilgio) buvo diagnozuota televizinės įrangos GULLYVER pagalba. Nustatyta, kad vamzdyje yra išilginis trūkimas. Ištyrus esamas aplinkybes, priimtas sprendimas renovuoti vamzdyną betranšėjiniu būdu priverstinio įtraukimo metodu. Pasirinktas įrenginys Grundotrack „Mini – Gigant“. Nustatyta, kad norint atstatyti nusidėvėjusį vandentiekio vamzdyną, būtina įtraukti naują PE slėginį vandentiekio vamzdį 200 mm skersmens. Grundotrack „Mini – Gigant“ įrenginiu sulaužius senus ketinius vamzdžius, PE vamzdžiai įtraukti be kliūčių. Suskaičiavus darbų sąmatas nustatyta, kad naujo vamzdžio įtraukimas priverstiniu būdu, naudojant betranšėjas technologijas, kainavo 89168 Lt. Tokio pat vamzdžio paklojimas atviru būdu (iškasant tranšėjas) būtų kainavę 108008 Lt. Nuotakyno sistema (380 m ilgio) iš keramikinių 300 mm skersmens vamzdžių pirmiausia buvo diagnozuojama telekamera TELEMEC 100. Nustatyta, kad vamzdynas labai blogos būklės (išilginiai, skersiniai trūkimai, vamzdžio sandurų prasikeitimai ir trūkimai) ir reikalinga skubi vamzdyno renovacija. Ištyrus esamas aplinkybes, priimtas sprendimas renovuoti vamzdyną betranšėjiniu būdu, taikant rankovės metodą. / The final paper analyses the condition of the water supply and sewerage collection network pipelines of Vydūno street, Jurbarkas. First of all, the line of the cast iron pipes (160 meter long) of the water supply system were diagnosed by the use of the television equipment GULLYVER. Longitudinal split in the pipe was discovered. Upon examination of the existing circumstances, the decision was made to renovate the pipeline by trenchless mode, by applying forced pulling method. The device Grundotrack Muni – Gigant was selected for completion of this task. It was established that in order to restore the worn water supply pipeline, a new PE pressure water supply pipe of 200 mm diameter needs to be installed. After the old cast iron pipes were broken by the device Grundotrack Mini - Gigant, the PE pipes were installed without any problems. Having calculated the work estimates, it was established that installation of the new pipe by forced method, through application of trenchless technologies, cost LTL 89168. Open laying (by excavating trenches) of the same pipe would have cost LTL 108008. The sewerage system (380 meter long) consisting of 300 mm diameter ceramic pipes was initially diagnosed by camera TELEMEC 100. Very poor condition of the pipeline was determined (longitudinal, cross fractures, changes and fractures of the pipe joints) and need for urgent renovation of the pipeline was established. Upon examination of the existing circumstances, the decision was made to... [to full text]

2009 m. Vilnius taps Europos kultūros sostine. Tai svarbus įvertinimas, rodantis visos Europos pasitikėjimą mumis kaip išsivysčiusia valstybe, kurioje verda aktyvus kultūrinis gyvenimas. Šis įvertinimas tartum simbolizuoja, kad mes žinome ar bent jau esame susipažinę su savo valstybės kultūra istorijos tėkmėje, sugebame ne tik išsaugoti, bet ir sąmoningai bei tikslingai panaudoti paveldą. Šiandien būdas susipažinti su senąja vandens tiekimo ir apšvietimo technika, galima sakyti, yra vis dar paties susidomėjusio reikalas. Nepaisant padidėjusio susidomėjimo technikos paveldu, šios kol kas specifinės paveldo srities populiarinimas žengia pirmuosius lėtus žingsnelius. Šio darbo objektas – technikos paveldas, o tiksliau apšvietimo ir vandens tiekimo įranga Vilniaus mieste. Iš karto reikia pastebėti, kad tai gana specifinė sritis, nes susijusi su buitimi. Buitis kaip kasdienybės elementas nėra ir niekuomet nebuvo vertinama. Miesto ūkio elementai jų panaudojimo metu niekuomet neturi išliekamosios vertės ir išlieka „nepastebimi“. Tuo labiau į juos nežiūrima kaip į kultūrinį reiškinį. Kasdieninio buitinio gyvenimo istorija, jo reikšmė ir įtaka to meto kultūrai yra tiriama praėjus kelioms dešimtims, o dažniausiai ir šimtams metų. Tai yra būdinga ne tik praeities kartoms, bet ir mums. Buitis tampa istorija tik pasikeitus aplinkai, kuri, reikia pastebėti, šiandien kinta daug sparčiau nei vos prieš šimtmetį. Dėl šios priežasties didžioji dalis technikos paveldo mums šiandien pažįstama tik... [toliau žr. visą tekstą] / In 2009 Vilnius is publicized as European Cultural capital. It means that our country lives an active cultural life. It’s like a present to us symbolizing that Lithuanians understand their history, culture and heritage; that they know how to save and use it for esthetical, financial, cultural or other purposes. Object of this work – technical heritage, specifically street lighting and water supply equipment in Vilnius. This is a range of small technical heritage directly related with domestic daily life that means no attitude for saving it like a worth thing. It’s not only nowadays problem. Domestic life attributes like lanterns, street lamps, water pumps, water towers, water wells and etc. has never been saved as cultural heritage as it was used constantly. Only becoming history known by the archival documents and iconography, domestic equipment sometimes attains attention. Paradoxical, but only when we have almost nothing left, we try to save it. At the moment we have 12 Vilnius water supply and street lighting objects written into Cultural heritage register – Verkiai manor lantern poles, 1 water pump, 4 water towers, 5 water mills and Vingriai spring reservoir. It’s a little number of technical heritage left, but it shows that we do remember it and somehow try to keep it for future. At the moment all the water towers, water pump and Pučkoriai water mills are saved only by not letting them to demolish. Today these objects give no any information. Better situation is with...

The tendencies of changes in water consumption are discussed in this final master’s studies research during different periods. The object of the research was chosen the biggest Lithuanian cities such as Vilnius, Kaunas, Klaipeda, Panevezys and Siauliai, also the lower reaches of the Nemunas, the basins of the Venta-Lielupe and the Neris. The purpose of the research is to collect and to analyze the data about the water consumption and its tendencies of changes and to do the analysis of factors, which influence water consumption. This research paper analyses factors, which could influence the increase or decrease of water consumption. These factors might be the decrease of production amount, increasing water tariffs, the establishment of water-meters, low incomes of citizens, old water-supply systems, which influence bad water quality for consumers. Whereas designed water-supply do not match current standards of water consumption, water is held there for too long and this could influence connecting new water consumers. However at present land’s economy revives, the GDP is increasing and so the incomes of citizens increase too, which influence the increasing standards of water consumption, although they have not reached the level of the standards in 1989-1990. Analyzing statistical data about water consumption there was looked for a connection between the amount of consumed water and unemployment. Also analyzing the dependence on middle income and the level of water... [to full text]
