Low volume roads
Kučera, Vlastimil ; Stehlík, Dušan (referee) ; Hýzl, Petr (advisor)
Thesis deals with an issue of low-volume roads and brings basic informations about their design. The most of the low-volume roads in the world are unpaved roads, while in the Czech republic there are not enought of experience with their construction, therefore a foreign literature was used as an almost exclusive source. The advantages of the roads with unpaved materials are, they are environment-friendly and money saving, therefore when correct procedure is used, good quality material is chosen and proper maintenance is used, they are advisable alternative to normally used asphalt surfaces. With increasing volume of vehicles their advantages decreases. They are suitable for a road surfaces in protected landscape areas, because they represents minor impact on the landscape.

Cleaning effect of unconventional filtration materials
Fialová, Tereza ; Hynánková,, Eva (referee) ; Kriška-Dunajský, Michal (advisor)
Constructed wetlands and the soil filters are water treatment devices using the filter material that in most cases consists of natural river gravel, coarse sand or crushed stone. Master´s thesis deals with the research of cleaning effect of unconventional filtration materials, or more precisely with examination to load real waste water in a filtration column, to prove their ability to be used as an alternative medium that can ensure better cleaning effect. For the research work following metallurgical industry materials were used: fine slag and coarse slag 8-16 mm, materials from the natural character: zeolite, keramzit, a plastic material: PUR-foam. Also the traditional materials of fine gravel and coarse gravel were tested to compare the cleaning efficiency. Both the hydraulic and the cleaning efficiency of all above mentioned materials were tested. The examined hydraulic parameters are particularly porosity, hydraulic conductivity and suspended solids, turbidity and oxidation-reduction potential of both the inflow and outflow of the filter columns were determined. Accredited laboratory set the inflow and outflow of the filter columns BOD5, CODCr, total phosphorus, total nitrogen, nitrite, nitrate, ammonia and dissolved oxygen. By evaluating the results of the measurements it is determined which materials are suitable to be applied in the constructed wetlands and the soil filters. This filtration column was modeled by program HYDRUS and the result was compared with real results.

Belt Conveyor
Hykolli, Denis ; Malášek, Jiří (referee) ; Kašpárek, Jaroslav (advisor)
The aim of this bachelor thesis is to design and calculate the inclined belt conveyor for the transport of gravel with the size of the fraction 16 - 32 mm, the difference between the end stations is 6 m and the material flow rate 100 000 kg per hour. This thesis includes analysis of transported material, brief description and distribution of belt conveyors, functional calculation according to standard ČSN ISO 5048, description and selection of components based on calculations, strength check of belt and subsequently driven drum. The thesis is accompanied by the required drawing documentation.

Implementation of Apartment House for Social Housing in Starec - Building Contruction Project
Bobek, Vojtěch ; Nečasová, Barbora (referee) ; Liška, Pavel (advisor)
Master thesis focuses on complex conducting of the technological project with accented earthwork, laying foundations and ceiling construction. Apartment building consists of two floors and is based in complicated geotechnical conditions which require changing subsoil and laying a foundation slab. The main aim of this thesis is a proposal of technological notes, time and financial management, selection of machinery, transport to the building site, work safety regulations, quality check of the conducted work and construction organisation.

Belt conveyor for gravel
Zeman, Vít ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
The bachelor's thesis deals with the design of a belt conveyor for the transport of gravel. The used machine parts occurring in belt conveyors are analyzed here. The work contains a computational part focusing mainly on the design of drive power. The conveyor is composed of existing manufactured components, as well as components designed by me. The resulting design of the belt conveyor is modeled and described by assembly drawings. The work focuses on belt cleaners. Their possible location and construction are discussed in the research part.
