Vpliv gradnje cevovodov pod prometno infrastrukturo na promet in okolje : diplomska naloga

Končan, Luka (author), Rijavec, Robert (mentor)

V diplomski nalogi so na splošno opisane tradicionalne metode gradnje cevovodov pod prometno infrastrukturo in tehnologije gradnje cevovodov brez izkopov. Na kratko je predstavljen tudi razvoj tehnologij gradnje cevovodov brez izkopov skozi zgodovino in njihov pomen pri razvoju sodobnega gradbeništva. V prvem delu naloge se opredelimo do pojma družbeno-ekonomski kazalniki, jih na splošno opišemo in pojasnimo njihov pomen pri gradnji cevovodov in vzdrževanju prometne infrastrukture. Predstavili smo tudi sodobno programsko orodje za določanje vplivov družbeno-ekonomskih kazalnikov pri projektih. V praktičnem delu naloge smo izvedli primerjavo med teoretičnim prekopom izvedenim po tradicionalnih metodah in horizontalnim usmerjenim vrtanjem z radijskim vodenjem. Primerjava je bila narejena na že izvedenem projektu izvedenim s horizontalnim usmerjenim vrtanjem. Za teoretični prekop smo uporabili teoretične vrednosti in predpostavke ter realne cene. Pri tem smo si pri finančni analizi pomagali s programom za vrednotenje investicij in z njim ovrednotili ključne družbeno-ekonomske kazalnike. S tem smo na praktičnem primeru pokazali kako se družbeno-ekonomski kazalniki lahko upoštevajo pri načrtovanju projektov in investicij, saj se odražajo predvsem v stroških uporabnikov in eksternih stroških. Na koncu smo ugotovili, da je bila izbira tehnologije gradnje cevovodov brez izkopov pri gradnji izvedenega projekta primerna in upravičena. S tem smo tudi potrdili, da so tehnologije gradnje cevovodov brez izkopov primernejše za gradnjo cevovodov na prometnih in gosto poseljenih območjih.

• Title: Impacts of constructing of pipelines under traffic infrastructure on traffic and enviroment : graduation thesis

Abstract

In the thesis are there generally described traditional methods of constructing (open cut trenching) of pipelines under transport infrastructure as well as technologies of construction of pipelines without excavation (trenchless construction). There is also briefly presented development of trenchless building of pipelines throughout history and its importance in development of modern civil engineering. In the first part of the thesis is there defined a concept of socio-economic indicators including also their general describing and explaining of their importance in construction of pipelines and maintenance of transport infrastructure. There is also explained a modern software tool for determining of influence of socio-economic indicators on infrastructure projects. In the practical part of the thesis is there described a comparison made between one theoretical example (a traditional open-cut trenching) and one real example of a trenchless system called horizontal directional drilling (HDD). For the theoretical example were there used theoretical values and presumptions and real prices. The financial analysis was made with help of a program for investment evaluation which evaluated the key socio-economic indicators. In this way was there on a practical example defined how some important socio-economic indicators can be taken into account when planning projects and investments as they are mainly reflected in costs of users and external costs. At the end it was found out that our decision about using of a trenchless technology for construction of the above mentioned real example was appropriate and justified. All these facts also confirm that trenchless technologies are more suitable for pipeline construction in traffic burden and densely populated areas.
