The aqueduct under the highway through of the microtunnel
Hoza, Martin ; Kunc, Jaroslav (referee) ; Horák, Vladislav (advisor)
During the construction of water pipeline Strelice is necessary to overcome the D1 motorway. This thesis deals with design of the motorway crossing using trenchless technologies. Combination of pipejacking and shield tunneling is chosen. Static calculation includes determination of the jacking force, proposal of the thrust block and assessment of the reinforced concrete jacking pipes.

Preparation and realization of the railway viaduct in Ostrov nad Oslavou
Šťastný, Jiří ; Doubek, Rostislav (referee) ; Kantová, Radka (advisor)
This Diploma thesis deals with the preparation of the realization of the railway viaduct in Ostrov nad Oslavou. Realization of major technological stages is addressed in building technological study. Technological processes of each sub-job phases are supplemented by technical regulations, the design of the main building machines and mechanisms, inspection and test plan, schedule of occupational health and safety, time and financial plan construction, construction budget, a plan for securing material resources. I also worked out the technical report of the building sites facilities including drawings needed. I also worked out design rehabilitation of the substructure of the railway viaduct, which is consist of technical regulations for remediation work and drawings.

City circle road Blanka, tunnel Královská obora - mined section, preparation and building construction technology
Kobielusz, Petr ; Mohapl, Martin (referee) ; Šlanhof, Jiří (advisor)
My thesis is focused on process preparation and building construction technology of primary lining road tunnel, implemented in city part of Troja in the capital city Prague. Specifically it is a part of tunnel complex Blanka. The name of this part is Kralovská obora. If the all tunnel parts are built this tunnel complex Blanka can be complemented to already opened tunnels Zlíchovský, Mrázovka and Strahovský which are the part of city traffic circle. This technology preparation includes schedules and financial plans of the building, technological prescription for the primary tunnel lining, safety plan, control and trial/test plans, environmental plan, project of construction site, design of the main working machines, items budget of the north tunnel tube, coordination situation plan with wider relationships transport routes and technical report of building technological project.

Permeability measurement of geocomposites on orthogonal specimens
Souček, Kamil ; Staš, Lubomír
The hydraulic conductivity coefficient of geocomposites is important parameter for evaluation of sealing chemical grouting. There can be problem with preparing of cylindrical gocomposite specimens by drilling for permeability measurements in some cases (e.g. specimens fall into small pieces of irregular shapes). In such cases shaping of geocomposite specimens is easier by cutting than drilling. The paper deals with concept of preparing and methods of hydraulic conductivity measurements at orthogonal geocsomposites specimens conditions. There are some results of geocomposites permeability measurements in this paper.

Laboratorní zkoušky geokompozitů se zainjektovanou diskontinuitou
Souček, Kamil ; Staš, Lubomír
Příspěvek se zabývá novými poznatky z oblasti cílených úprav vlastností horského masivu pro geotechnické účely na základě zkoumání vlastností geokompozitů na bázi hornin skalního typu a chemických injektážních médií včetně jejich reologického a chemoreologického chování zvláště pak se zaměřením na epoxidové materiály, které nejsou v naší injektážní praxi běžně používány. V příspěvku jsou diskutovány a uváděny zkušební metody a postupy pro výzkum jak čistých injektážních médií, tak geokompozitů se zainjektovanou diskontinuitou, které umožňují optimalizaci výběru injektážního média pro ovlivňování vlastností horninového masivu.
