Chrudim - Borohradek Railway Track Reconstruction (section between km 13.847 and km 16.750)
Veits, Lukáš ; Bombera, Ing Jan (referee) ; Říha, Tomáš (advisor)
The aim of this thesis is to adjust the geometric parameters of railway tracks and reconstruction of the superstruction on the one-track no.016 Chrudim - Borohrádek in the section km 13,847 - 16,750. When reconstruction is needed to solve a level crossing by applicable law and renovation of the drainage design.
Building Alterations of the Track Section Tisnov - Nedvedice allowing 30 minute Clock-face Scheduling of the Passenger Trains
Moldovan, Lilija ; Křemen, Tomáš (referee) ; Říha, Tomáš (advisor)
This bachelor thesis deals with the possibility of designing a 30-minute time at Tišnov - Nedvědice and building modifications connected with its implementation. In the implementation of the time, the continuity of existing connections is taken into account.
Hanusovice - Jesenik Railway Track Reconstruction (section between km 9.400 and km 12.329)
Machová, Petra ; Šmíd, Jaroslav (referee) ; Říha, Tomáš (advisor)
The objective of my bachelors thesis is the reconstruction of single-line railway track Hanušovice – Jeseník in km 9,400 - 12,329 track section. Design of track geometry parameters and permanent way assembly is the main part of this work. Solve problems with railway crossings and drainage system is necessary during the reconstruction.
Olomouc - Sumperk Railway Track Reconstruction (section between km 35.2 and km 38.2)
Benáčková, Jana ; Malý, Tomáš (referee) ; Říha, Tomáš (advisor)
This bachelor thesis is focused on the design of the modification of the geometric parametes of the track and the reconstruction of the railway superstructure on the Olomouc – Šumperk line on the section km 35,2 – 38,2. During the reconstruction it is also necessary to solve railway crossing according to the regulations and the recontruction of the drainage.
Spatial materials for additive manufacturing in civil engineering
Říha, Tomáš ; Apeltauer, Tomáš (referee) ; Podroužek, Jan (advisor)
The bachelor thesis deals with additive manufacturing in the construction industry and with materials used in this field. The first part of the thesis defines the 3D printing, briefly describes the history of this progressive technology and gives an overview of the used methods and technologies. The printing methods are divided according to the physical state of the basic material used for printing. The next part of the thesis presents the possible use of additive manufacturing in the construction industry and an overview of realized projects. Finally, at the end of the theoretical part are introduced materials applicable to additive manufacturing in the construction industry and is defined the concept of spatial materials. Spatial materials are a relatively new term, which is not yet in the literature sufficiently defined. These materials can be used for an application in a space where the structure and the position of their particles can be optimized. They can be applied for the creation of 2D filling structures, which are more useful for geometrically simple and simply loaded constructions. It is preferable to use spatial materials to create 3D structures that are designed to fill numerically optimized structures. These structures are based on the principle of double curvature and on a triply-periodic minimum surface (TPMS). In the practical part of the thesis was created the design of building block filled with 3D gyroid structure, designed for prefabrication by using additive manufacturing in the factory or at the site of construction. This proposal reflects the increasing demand for easy individualization of constructions and building elements. Especially, the demand for the creation of structures and shapes which are topologically optimized with a customized appearance and sufficient strength, all at the customer's request.
Constructive technological project of warehouse
Říha, Tomáš ; Novotný, Michal (referee) ; Diaz, Yvetta (advisor)
The aim of the diploma thesis is to elaborate parts of the frozen food warehouse construction project in Dašice in the area of MD logistics as, resulting in the elaboration of a technical report on the building technology project, the coordination situation of the building with the broader relations of the transport routes, the time and financial plan of the construction in the plane of the buildings, implementation of the main technological stages of the main building, drawing of the building site equipment, design of the main building machines, detailed time schedule of the main building, budget line, technological regulation for implementation of foundation structures consisting of drilled pilot and supporting walls, quality control and test plan for the given stage , drawings of the earthworks equipment and the construction of the hall.
Dopad caespestechniky na kvalitu užitkových trávníků
Říha, Tomáš
Utility lawns are lawns that complete the human environment and that is why they need proper care. The objective of this study was to characterized the utility lawns and lawn care. Among the basic caespetechnique measures belong cutting, verticutting, aeration and fertilization. The lawn is necessary to cut as often that maximum 1/3 of the assimilation area would be removed. Verticutting removes lawn thatch of vegetation that prevents the access of water, air and nutrients to the root system. Pruning of the lawn is sufficient twice a year to a depth of 1.5 - 2 mm. Aeration aerates compacted vegetation substrate to a depth of 50 - 150 mm. For sandblasting is used a sharp silicious sand but it is also possible to use new materials such as a crumb rubber. It is necessary to divide the dose of fertilization into several terms to ensure the functionality of the lawn across whole vegetation season. Nitrogen fertilization encourages lawn density by having better offshoots of grasses. The plant tissues are stronger by supplying the required amounts of phosphorus and potassium and it also increases resistance to drought, cold temperatures and fungal diseases.
Hanusovice - Jesenik Railway Track Reconstruction (section between km 23.300 and km 26.269)
Mikulenka, Lukáš ; Sobotka, Lukáš (referee) ; Říha, Tomáš (advisor)
The objective of the bachelor thesis is to propose the modification of the geometric parameters of the track and the reconstruction of the permanent way of the single - rail railway Hanušovice - Jeseník in the section from km 23,300 to km 26,269 (from the beginning of the switch 5 in Horní Lipová railway station). Part of the reconstruction is also the crossing P4289 and renewal of the drainage.
Veseli Nad Moravou Station Reconstruction
Klar, Vít ; Sobotka, Lukáš (referee) ; Říha, Tomáš (advisor)
The subject of the Master's thesis is to design the redevelopment of the Veseli nad Moravou railway station. This renovation will include renewal of both, railway superstructure and substructure, including drainage system and new platform construcion proposal in order to meet current legislation regarding access of persons with reduced mibility and orientation skills. This thesis also deals with design of the track geometry compoments and geometry of set of switches at both heads of the railway station to fulfill the maximum train velocity demands at certain tracks. Last but not least, the rail track scheme of the station has been simplified.
Competitiveness Improvements of Railway Passenger Transport in Section Unicov - Sumperk
Melecký, Martin ; Kubina, Jiří (referee) ; Říha, Tomáš (advisor)
The thesis target is to design construction treatments resulting in improving the passenger railway transport in this section. Planned modernization and electrification will change the transport nature significantly, which calls for an examination of the existing track possibilities. The task was to focus on the regarding stations as a crucial troughput aspect and on the travel quality improvment by minor construction adjustments. I have examined walking distances, designed a new Troubelice - Centrum stop. By convenient platform shifts higher velocities criteria were met. All precautions respect the wheelchair access. The station design allows higher velocities operation and do not restricts current use.
