Technology of Trenchless Rehabilitation of Pipelines
Pleva, Ondřej ; Fic, Miloslav (referee) ; Kárník, Jan (advisor)
Contend of bachelor thesis is aimed on trenchless methods of rehabilitation underground pipe networks. It includes several repairs, renovations and replacements without need of open cut. At its beginning, thesis is focused on classification of different types of pipe defects, their localization and cleaning methods. Mentioned activities are in most cases essential part of pipe rehabilitation. Main part of thesis is dedicated to detail description of individual rehabilitation methods. At the end the aim of the thesis moves toward assessment and cooperation of trenchless methods in relation one to another and also in relation to open cut.

Desin of new technologies for invert grouting of masonry sewer
Dolák, Martin ; Melichar, Tomáš (referee) ; Drochytka, Rostislav (advisor)
The subject of this work is to find optimal grouting mixture for repairing existing brick sewer with insistence on ecological modesty. Secondary raw and waste materials will be evaluated as a partial replacement of good-quality materials, that are commonly used. Production wastes for which is after necessary adjustment found usage in another sphere of production are named secondary raw materials. In the end will be made a selection of appropriate secondary raw materials for a project of new technology of back grouting identified for repairing currently used brick sewers.

Development of new grouting materials for reverse grouting of sewers
Dolák, Martin ; Dohnálek,, Pavel (referee) ; Drochytka, Rostislav (advisor)
ABSTRACT This thesis deals with the development of silicate based reverse grouts for the purpose of rehabilitation of sewers. The work also examines the possibility of substitution of basic input raw materials with secondary raw materials, meaning replacements of both filler components and binder components. As secondary raw materials, we refer to wastes from the production process which, after the necessary treatment, are used in another production. The development and experimental verification of the functionality of the developed grout was focused mainly on the use of secondary raw materials as much as possible, while maintaining or even improving its physical and mechanical properties. Based on the results of the work, it can be stated that with a 100% replacement rate of filler components in combination with 20% replacement rate of binder components, it is possible to largely maintain the properties of the material, or even optimize them. The results of the thesis also point to the possibility of reducing the economic and environmental demands of production of building materials.
