Rainwater management in urban areas
Haška, Aleš ; Malaník, Stanislav (referee) ; Raclavský, Jaroslav (advisor)
The thesis focuses on the issue of stormwater management in urban areas with a focus on vegetated roofs . In this paper, testing of vegetated roof compositions at the DERIC experimental centre is published. The compositions are tested here to refine the existing knowledge on the behaviour of vegetated roofs in real environments. The existing knowledge of vegetated roof compositions is presented. The paper also explains how to input these specific vegetated roof compositions into the LID (Low Impact Development) module, which is part of the SWMM (Storm water management model) program. For each roof, parameters were compiled during which the simulated composition showed the greatest agreement with the measured data. After a satisfactory match, two compositions were selected and implemented in a specific area. For the specific area, there is already a rainfall-runoff model built from a previous research project, but new sub-catchments needed to be generated for this model and this was achieved using the PYTHON programming language. Subsequently, analyses of runoff reduction from the area of interest were performed.
Usage of polymer modified bitumens and rejuvenators in asphalt mixtures
Maláník, Stanislav ; Hýzl, Petr (referee) ; Dašek, Ondřej (advisor)
Diploma thesis deals with the influence of various dosing of Reclaimed asphalt pavement (RAP) using modified bitumen on the properties of asphalt concrete (ACO 11+) of cemented by polymer modified bitumen, while a rejuvenating agents are added into asphalt mixtures. The theoretical part of the thesis summarizes the basic knowledge of pavement recycling, polymer modified bitumens and their reuse in asphalt mixtures. The practical part deals with laboratory tests of ACO 11+ mixtures with the RAP proportion of 0 % to 50 %. The asphalt mixtures compared are evaluated by means of the Thermal Stress Restrained Specimen Test (TSRST) and Stiffness test. The results obtained within the diploma thesis can approximate the issue of recycling of asphalt mixtures with polymer modified bitumens.
Properties of reinforcing glass-fiber geogrids in pavement structure
Maláník, Stanislav ; Šperka, Pavel (referee) ; Dašek, Ondřej (advisor)
Bachelor's thesis deals with the use of glass fiber reinforcement geogrids in road construction. Bachelor's thesis is focused on basic knowledge of reinforcing geosynthetics and on summary of existing regulations concerning the use of geogrids in roadway. The influence of the construction of the road layers on the change of the geogrid properties is evaluated by suitable tests. In particular, the effects of the impact of the movement of the construction technique on the geogrid and the effects of the compaction of the overlying layer on the geogrid properties were simulated in the laboratory.
Design of sewer network rehabilitation of choice parts of urbanized areas
Horák, Ondřej ; Malaník, Stanislav (referee) ; Raclavský, Jaroslav (advisor)
The thesis approaches the problem of design of sewer network rehabilitation of urbanized area named Kamenná čtvrť. The thesis is divided into several parts. In the first part of the thesis there is the accompaying report, which describs characteristics of the area as a whole. The second part of the thesis is about describing each part of the network, clasification of defects according to the ČSN EN 13508 -2 and fothcoming TNV 75 6905 and photographs from network camera survey. In the third part of this thesis there is a chart with all defects located on the network. Also there is an evaluation of each part of network according to prepared TNV 75 6905. The fourth part of the thesis talks about evaluation of each part of the network as a whole. In the fifth part of the thesis we design possible choises of reahabilitation on the network. The sixth part of the thesis contains the economic aspects of possible alternatives and their comparsion. Last part of the thesis contains a hydrotechnical calculation, which means calculation of the current situation and the possible alternatives. There is an individual evaluation of the calculation and if its necessary optimizations of the network.
Design of Sewage Pumping Stations
Káda, Leoš ; Malaník, Stanislav (referee) ; Raclavský, Jaroslav (advisor)
Theme of bacherol thesis is Design of Sewage Pumping Stations. Main purpose of this theme is create basic reference book for design of sewage pumping stations. Next intention of this thesis is to bring the newest information on both submersible pumps and pumping stations.
Pump Control in Water Supply
Kvapil, Radek ; Malaník, Stanislav (referee) ; Kučera, Tomáš (advisor)
The bachor thesis deals with a description and construction of pumps and automated pumping stations. The first part concerns the classification of pumping technology and the way of pumping machines controlling. Then, it also discusses the reduction of operational costs and an analyzes consequences of water loss in pipes, and preassure. The final part of the thesis practically analyzes an in-question location and a proof of advantages pumping of technology modernization.
