RECONSTRUCTION TECHNOLOGY OF THE VIADUCT LEŠNICA

Premostitveni objekti so pečat okolja v katerem služijo svojemu namenu. V okolici so vedno v središču pozornosti, zato je za gradbeno stroko gradnja takega objekta velik izziv. Diplomsko delo najprej opisuje različne mostove in materiale ter tehnologije s pomočjo katerih taki objekti sploh nastanejo. V nadaljevanju je opisano obstoječe stanje viadukta Lešnica, ki je bil potreben prenove. Poudarek diplomskega dela pa je na izbrani tehnologiji rekonstrukcije viadukta s postopnim narivanjem nove prekladne konstrukcije in hkratnim odrivanjem obstoječe prekladne konstrukcije. Ta inovativen način zamenjave premostitvene konstrukcije je bil v Sloveniji uporabljen prvič.Bridging facilities are the seal of the environment in vhich they serve its purpose. In the vicinity they are always in the spotlight, so construction of such a facility is for the building profession a big challenge. Thesis first describes different bridges and materials as well as technologies through which such facilities even arise. Below is the current state of viaduct Lešnica, which needed renovation. Focus of the thesis is on the selected reconstruction technology of the viaduct with incremental launching method of the new structure and simultaneously suppression of the existing bridging structure. This innovative method of replacing a bridging structure was used for the first time in Slovenia
