Využití bentonitových izolací v dopravním stavitelství

Abstract

Dissertation is directed to examine the characteristics and assessment of bentonite´s insulation for use in the transport sector, mainly for the construction of the tunnels-underground construction. Solution for this issue is the work divided into four parts. In the first part of the bentonite´s insulation properties are verified using tests of insulating materials of isolatin in the simulation environment for the incorporation of the insulation to the definitive structure. In the second part is a detailed study of the charted data on the realization of bentonite´s insulation in the construction of tunnels in the open pit construction pressurised environment. These results are reflected in the third part to optimize the design details of the isolating system, and the inventory of risk depending on the conditions of realization of large buildings and pressurised environment. The fourth part of the dissertation addresses the assessment of the application and a detailed draft of the insulating system, including technological process for mining tunnel construction. Use of tests carried out, and the mapping of the implementation, including the activation of the bentonite´s insulation have managed to clarify the actual insulation of the function and behavior of bentonite´s insulation on large construction sites with the insulation of unfavourable environmental conditions and thus at least partially fill in the missing space in the normative technical regulations.
