Porovnání razících metod při ražbě kanalizačního sběrače

Abstract

In this bachelor work i will compare two technologies of building an underground engineering networks. The first technology is conventional method of excavation, where it's necessary to do basic operations such as disonnection, mining and disposal of the muck. Then the extrados needs to be secure by steel ribs and sprayed concrete. The second technology is mechanized excavation per tunelling shield. This technology is based on a core barrel, which is with the help of hydraulic ram by pushing into the muck. At the same time we disconect and dispose the muck. Also we impose the segmental linings rings at the tail skin.
