Design of excavator
Brza, Lukáš ; Zdařil, Zdeněk (referee) ; Křenek, Ladislav (advisor)
The design of the excavator follows requirements of machines for demolition work. The excavator is equipped with an innovative type of under carriage, which not only increases mobility over the demolition sites but also the visibility from the driver’s cabin. The components of the excavator, that improve the demolition work, are special types of tracks, suspensions and articulated steering. Tracks can change their shape to increase the stability and also to adapt to the diff erent types of ground. The suspensions with tracks are able to adapt to the terrain thereby they lighten the asperity. Suspension can also tilt or even raise the excavator and thereby increase the angle of visibility from the cabin. This function is necessary mainly when taking down higher constructions. Articulated steering is a new function that has never been used for excavators. This steering was chosen due to fl exible movement over demolition sites. The main aim of the project is to create a new design of the excavator, but more importantly to distinguish the excavator from the excavators already on the market, with regards to its esthetics and under carriage innovation.

Multifunctional center Hlinsko - preparation and realization construction.
Šusták, Miroslav ; Rychtecký, Martin (referee) ; Kovářová, Barbora (advisor)
Diploma work Multifunction Centre Hlinsko - preparation and realization of the covers technological studies throughout the building. Diploma work proposes a temporal, financial and material resources. The work included construction budget, schedule of work, technical regulations for demolition, implementation and installation of reinforced concrete ceiling glulam beams. For each technological regulation is developed inspection and test plan. The work includes the project site equipment. Diploma work is based on the technical documents supplied by the designer. The work also includes specialty.

Technical survey of the family house
Odstrčil, Štěpán ; Láník, Jaromír (referee) ; Schmid, Pavel (advisor)
This bachelor’s thesis deals with diagnostics of one object divided to 4 residence units. Technical construction resarch had to be made due to owned wants knock down his residence unit and build a new family house instead o fit. Object is located on the street Žebětínek 17 in Brno-Medlánky. Resarch includes enumeration of all damages before demoliton o rafter that, diagnostics of object wich is being demolished and consequences of demolition to buildings nearby.

Study the possibility of using recycled aggregate concrete for the manufacture of structural concrete
Skriňáková, Eva ; Stehlík, Dušan (referee) ; Hela, Rudolf (advisor)
This bachelor's thesis is aimed on the issues of using aggregate from recycled concrete rubble. The introduction describes the possibilities of concrete recycling and methods for fresh and hardened composite recycling. Next mentioned are physical and mechanical properties of recycled aggregate reused in concrete and comparison with natural aggregate concrete. Last part of theoretical section presents the opportunities of using recycled concrete to sub-base layers and concrete pavements. The practical section is focused on the application of recycled concrete aggregate to design concrete mixture of required strength class and verifying the possibility of usage in the exposure class XF3 and also design hydraulically bound course. The results of the practical section is to determine the suitability of recycled concrete usage for concept mentioned above.

SUBSTRUCTURE OF A TRAINING CENTER OF COMPANY BATIST
Možíš, Jan ; Hanzelková, Martina (referee) ; Kantová, Radka (advisor)
The subject of my bachelor thesis is the construction-technological project of a training center of company Batist, Červený Kostelec. Thesis is focused on the most optimal technological procedures of demolition and groundworks along with base designs substructures. Regulations are supplemented by inspectional and trial plans, appropriate machinery and equipment of assembly site. Included is also work safety, time schedule and budget of substruture. The most interesting thing of my thesis will be comparison of the financial foundation with the original design of reinforced concrete structures on foundation along with compaction of the substrate, the design of the building foundation on bored piles.

Analysis of work equipment that are suitable for recycling of construction materials and waste.
HOŠEK, Lukáš
The aim of my thesis is to give an overview and analysis of appropriate facilities for recycling construction materials and waste products. I deal with the generation of construction waste resulting from demolition procedures and examine the classification of the demolition waste and its subsequent usage in recycling materials processes. The work further addresses the usage of relevant earth-moving machinery in this sector, including relevant adapters for demolition works. The thesis also contains an overview of crushing units with selected technical parameters including theoretical performance. The main criterion for the distribution of mobile crushing units is the size of the inlet. The results of measuring cycles and data for the calculation of the efficiency of crushers at particular work in the processing of construction debris are also given. The actual performance values are compared with the theoretical ones. In all cases, the actual performance is lower than the theoretical one.

Využití stavebních a demoličních odpadů
Výzkumný ústav vodohospodářský T.G. Masaryka, Praha ; Svoboda, Karel
Studie obsahuje rozpracování návrhů: - jednotného systému posuzování jakosti recyklátů, - optimálního podílu recyklace z celkově vyprodukovaného stavebního a demoličního odpadu, - posuzování materiálového využití stavebního odpadu vzniklého při zřícení a demolicích budov po záplavách a povodních. Dále se zabývá identifikací technologických postupů pro recyklaci a nakládání se stavebními a demoličními odpady. Popisuje současný stav technologických a kapacitních možností využívání stavebních a demoličních odpadů v ČR (produkce stavebních odpadů, recyklace stavebních odpadů a příklady použití recyklovaných stavebních materiálů).

ANALYSIS OF THE USE OF MANIPULATION DEVICE FOR REMOVAL OF THE CONSEQUENCES FLOODS CAUSED BY TORRENTIAL RAIN.
HOLBOJ, Martin
The aim of this thesis is a simplification of the decision-making process during the removing of results of floods caused by rainstorms. The work analyses reasons of floods and indicates possible ways of efficient usage of the supporting machinery fitted with appropriate tools. Right after the flood the most important goal to prevent chaos is to get people affected by the flood back to their homes and restore their everyday life as soon as possible . Within this time the quality of the machinery used is not that important. However, the know-how concerning using the equipment is crucial.
