Primerjava klasične gradnje infrastrukturnih vodov s tehnologijo gradnje mikropredorov : diplomska naloga

Kolar, Martin (avtor), Pulko, Boštjan (mentor)

V diplomski nalogi je podrobneje obrazložena tehnologija gradnje mikropredorov. V nalogi smo predstavili zgodovinski razvoj tehnologije na svetovnem trgu in razvoj v Republiki Sloveniji. Podrobneje smo predstavili komponente strojnega dela tehnologije in njihove principe delovanja ter osnovni princip delovanja celotnega sistema. V prvem delu smo v celoti zavzeli teoretični in tehnološki del tehnologije gradnje mikropredorov. Nekaj besed smo namenili še opisu drugih obstoječih tehnologij na trgu. Drugi del diplomske naloge je finančna analiza in primerjava gradnje mikropredorov ter klasične gradnje. V tem delu smo podrobno opredelili potrebna finančna sredstva in popise del. Za primerjavo niso bili primerni projekti, kjer je gradnja mikropredora zaradi projektnih zahtev v prednosti (prečkanja avtocest, železnic in širših vodotokov). Analizo smo naredili na dveh projektih. Analizo prvega projekta smo naredili na hipotetični lokaciji ob ustreznih predpostavkah, ker nismo uspeli pridobiti izvedenega projekta, kjer bi ravninski odsek z minimalnim premerom cevi DN800 presegel dolžino 250 m in dosegel minimalno globino 6 m. Glede na upoštevane predpostavke smo pokazali, da je projekt izveden s tehnologijo gradnje mikropredorov cenovno ugodnejši, z veliko manjšim vplivom na okolico. Druga analiza je bila narejena na realnem projektu, ki se je izvedel v letu 2015. Ob projektnih podatkih in ustreznih predpostavkah smo pokazali, da mikropredor v tem primeru ne bi bil ekonomsko upravičen.

• Naslov: Comparison of traditional open cut methods and microtunneling for the installation of buried infrastructure : graduation thesis

Izvleček

In this thesis we have described the microtunneling technology with all the technical details. The history of the implementation of microtunneling method in Slovenia and the begging off microtunneling use on the global scale is presented. The hardware components and the mode of operation with some the theoretical background are described in detail in the first part off the thesis. Besides that, some other trenchless technologies which were used in in Slovenia are briefly mentioned. In the second part off the thesis, the microtunneling technology and open cut method of construction for the installation of buried infrastructure are compared. In the analysis we have to exclude all the projects that are in favor of microtunneling system (crossing railways and highways). The technical comparison and detailed cost analysis between open cut construction method and microtuneling technology was made for two different projects. The first project is hypothetical one and is based on some assumptions, because we did not succeed to obtain the data of an executed project for buried infrastructure exceeding 250 m in length, with the diameter of pipe at least 800 mm and with minimum depth of 6 m. In the first analysis, we have shown that microtunneling is better and more economical solution than the open cut method. The second analysis was based on real project that was finished in 2015. Do to the nature off the project and its technical characteristics, we have concluded, that microtunneling system is not an economical and better solution than open trench system.
