Abstract

Namen magistrske naloge je predstaviti nekaj praktičnih podrobnosti in bistvenih faz, ki jim mora slediti vsak uspešno izveden projekt mikrotuneliranja. Tehnologija gradnje brez izkopa vključuje različne tehnike za izgradnjo novih cevovodnih omrežij, prav tako pa tudi sanacije obstoječih cevovodov pod prometno infrastrukturo, kot so ceste in železnice. Tehnologije gradenj brez izkopov omogočajo manjši poseg v prostor, omogočajo tudi promet v času gradnje, v nekaterih primerih so tudi cenejše v primerjavi s klasičnimi metodami izkopa. V teoretičnem delu magistrske naloge smo na kratko opisali mikrotuneliranje, podali analitične podlage za izračune ter povzeli parametre, ki vplivajo na mikro tunele. Podali smo smernice za načrtovanje in izvedbo cevnega narivanja. V praktičnem delu smo izračunali primer, ki vključuje izračun stabilnosti čela mikro tunela, silo na vrtalno glavo, stabilnost mikro tunela, deformacije tal, posedek tal, trenje na obodu cevi in obremenitve na cevnih spojih. Na koncu smo naredili primerjavo med različnimi parametri.

Secondary title:	Design procedures of micro tunnels
Secondary abstract:	The purpose of the master thesis is to present some practical details and essential phases that every successful microtunneling project should follow. Trenchless technology includes various techniques for construction of new networks, as well as a renovation of existing networks under transport infrastructure such as roads and railroads. Trenchless technologies allow a minimal interference to surroundings, allow also traffic during installation, and in some cases are also less expensive compared to open cut trench excavation. In the theoretical part of the master’s thesis, we briefly described microtunneling, gave analytical bases for calculations, and summarized the parameters affecting micro tunnels. We provided guidelines for project design and execution of pipe jacking. In the practical part, we calculated an example which includes a calculation of tunnel face pressure, face load, bore stability, ground closure, ground settlement, pipe friction and pipe joint loading. In the end, we made a comparison between different parameters.
