Možnosti odstranění zelených řas z betonových konstrukcí / The possibilities of green algae removal from concrete structures

Cochlárová, Milena January 2014 (has links)
This master´s thesis deals with the suppression of algal growth on concrete structures. The subject of the work is to design and coatings their own structural concretes containing protective element in order to inhibit the growth of algae. As the coating are tested commercially avaiable and newly created systems. Testing systems are based on the portland cement and chelates of metal (Cu, Ni, Co, Mn, Zn, Al).

Návrh sanace sesuvu Nedašova Lhota / The Design of Nedašova Lhota Landslide Securing

Janík, Michal January 2012 (has links)
The thesis called The Design of Nedašova Lhota Landslide Securing concentrates on the basic analysis of the problems connected with landslides and safety factors needed for the slopes stability. At the same time it presents a concrete solution to the given practical task, where the slope stability, the causes leading to the landslide and the subsequent redevelopment in view of financial requirements are discussed.

Polyfunkční centrum občanských aktivit / Multifunctional Centre of Civil Activities

Novák, Pavel January 2013 (has links)
The masters thesis dealt with reconstruction of the complex military garages built in the mid 20th century. The site is located in Brno, close to Peace Square, Lerchova 915/62, Brno-Stránice, 602 00 Brno. Area of land area is 5,384.25 square meters. Reconstruction involves two detached single-storey buildings, the street Lerchova object and the object at the Valley Street. The goal is the maximum possible use of existing quality substructure, which is a combination of internal reinforced concrete frame and brick outer shell. The work is divided into a comprehensive layout of both buildings and detailed sub-project for the construction project on a subject at street Lerchova. Reconstruction of the resolves completely change the layout and especially the concept of architectural design. In terms of architecture, wider relations into account the existing development, which tries to resemble the representation. The building is at street Lerchova basement one floor, built up area is 620.5 square meters. Reconstruction of superstructure solves one floor, making new pitched roof and building a walkway that allows connection between the two objects. Revitalization is due on the requirements of the public and addresses the widespread use of indoor and outdoor spaces as much as possible. It is particularly emphasized promote leisure activities not only public, but especially young people and support for education, mental and physical, education and counseling. We can not forget easily to most complex space by persons with limited mobility.

Nové typy kompozitů pro sanaci stavebních konstrukcí s důrazem na zvýšení korozní odolnosti výztuže / New types of composites for rehabilitation of building structures with emphasis on increasing the corrosion resistance of reinforcement

Dražil, Luboš January 2013 (has links)
This thesis is dedicated to the degradation of reinforced concrete structures, their causes and consequences of the waveforms. This thesis describes how the protection of concrete structures against these negative effects. The practical part of the work was focused on the development of new types of repair materials with added value in the form of corrosion inhibitor. In this part of the work was done adhesive bridge and development of repair materials for hand and machine application.

Vývoj správkové malty s odolností proti vysokým teplotám / Development of repair mortar with resistance to high temperatures

Šottl, Jiří January 2014 (has links)
Currently, increasing reinforced concrete structures and concrete structures that require repair in the form of remediation. The master’s thesis deals with the development of repair mortars with resistance to high temperatures, which would allow the re-profiling of the fire damaged parts of the structures and restore its function. Development of repair mortars is based on a literature review of articles dealing with research materials resistant to high temperatures.

Stavebně technologický projekt přístavby OPS Chaloupky / Construction and technology project of the extension o.p.s Cottages

Škrdlová, Anna January 2015 (has links)
The master’s thesis discusses the technological project for the reconstruction of school Chaloupky o.p.s in the countryside near Třebíče. Basic data about the building of the project are included in the technical report. The thesis deals in detail with the technological regulations Hurdis ceilings and reconstruction of arches. For these selected topics are made other documents which are needed for realization - building equipment, plan of health and safety, kontrol and test plans, draft of mechanization. The project also includes the time and financial plans and budgets for the main building. The project is supllied with selected structural details.

Posouzení stability skalní stěny a návrh sanačních opatření / Assessment of the stability of rock walls and design of remedial measures

Nevřalová, Jana January 2015 (has links)
The work aims to evaluate rock slope including static assessment and to estimate the financial cost. Static analysis is done manually and the program GEO 5. The proposal remediation is performed in 6 combinations of which one is selected and processed into project documentation.

Statické posouzení stávajícího železobetonového komínu / Structural assessment of the reinforced concrete chimney

Teplý, Jakub January 2017 (has links)
The aim of this thesis is assessment of existing condition reinforced concrete factory chimney, who has undergone structural and technical survey, under which was found many failures caused of horizontally tension - significant vertical cracks in the chimney stack. The object of this work will also make appropriate proposals rehabilitation of concrete stack by design prestressed cables monostrand in horizontal direction, grouting open cracks and reprofiling surface of chimney stack.

Ověření technologie BioSealing metodou EIS / Verification technology BioSealing by EIS method

Fránková, Hana January 2017 (has links)
Diploma thesis is dealing with recognition of Biosealing technology using electrical impedance spektrometry method. BioSealing is an innovative method of soil body reconstruction, which uses stimulation of soil bacterial activity to seal the leakage. The method was developed in the Netherlands and it was used in conditions of the Czech Republic in years 2015 and 2016 on the Hornice water work. This earth dam was monitored by electrical impedance spectrometry by apparatus with device Z-meter IV in this period and the data are processed and assessed in this diploma thesis.

In-situ reduktivní dehalogenace / In-situ reductive dehalogenation

Dvořák, Petr January 2018 (has links)
This master thesis is focused on groundwater remediation of chlorinated ethylenes and methanes in the area of chemical factory Spolchemie in the Czech Republic, Ústí nad Labem city. For these purposes nano zero valent iron particles were used. For the remediation two separate applications of different types of particles together in suspension with tracer (lithium chloride), were carried out. The results from the first application were evaluated by the supervisor of this thesis and are briefly summarized and discussed together with the second application which was evaluated by the author of this thesis. Second application of particles was carried out in October 2015 and observed for 424 days. Observation consisted of monitoring of groundwater level, physical-chemical parameters and collection of water samples for the analysis of concentrations of chlorinated hydrocarbons, their degradation products and several chosen ions. Nanoiron particles had the assumed effect onto the physical-chemical parameters and reduction of contamination. The application of tracer had proven the expected groundwater flow and made a possibility to distinguish between the process of reductive dehalogenation and dilution caused by the injected water, the dilution did not exceeded 5 % in most monitored points.
