Možnosti rekonstrukce asfaltobetonového těsnění a drenážního systému vodní elektrárny

2.9.2025 | Ing. Veronika Chrástová, prof. Ing. Jaromír Říha, CSc.
The Dlouhé stráně pumped storage power plant is located in the heart of the Jeseníky Mountains near the state border with Poland. In recent decades, the asphalt concrete shell of the upper reservoir has been struggling with complications in the form of local point failures, which manifest themselves as blisters on the surface of the shell with a diameter of up to 30 cm. Although the asphalt concrete shell was reconstructed in 2007, the blister problems reappeared a few years later and have been repaired every summer since then. An insufficient drainage system may be closely related to the problems on the surface of the AB shell. The limited possibilities for monitoring leaks along the route of the upper reservoir drainage system do not meet the requirements for accurate and local monitoring of leaks and, possibly, for detecting increased leaks that may indicate a dam breach. For these reasons, a proposal was drawn up for the reconstruction of the asphalt concrete shell together with the drainage system of the reservoir bottom.

Thermal Properties of Double Window and Modern Construcions Jamb

20.3.2023 | Ing. Lucie Kudrnáčová, Ph.D, ČVUT v Praze, Kloknerův ústav, Oddělení stavebních materiálů
The paper deals with the comparison of the thermal properties of jamb for different types of windows. In the case of reconstruction, it is often necessary to preserve the original double- windows or to use modern materials due to the thermal solution of the building. Modern constructions mean the use of double or single windows with thermal-insulating glazing. These changes in the construction of the window have an effect on the thermal processes on the structure. One of the important parameters for the assessment of the building structure is the assessment of the internal surface temperature of the building structure. This article shows the difference in finishes and heat flows to remove different types of windows. The reference window for comparison is the original double history window. The results were found in a model environment in 2D software.

Although the term wooden construction is not introduced in our legal regulations, we commonly understand this term as constructions in which wood and wood-based products are the main material used. However, the proportion of wood and wood-based products is not defined and depends on the construction system used. Wooden constructions are currently the subject of growing interest among developers, architects, civil engineers and the public. This is mainly due to the fact that they offer an alternative method of building construction with great ecological benefits. Their advantage is also the speed of construction and usually low demands on the equipment of the construction site. Technical standards are important for their design and implementation.

Účinok a požiadavky na tepelné izolovanie deliacich konštrukcií v bytových domoch

13.10.2025 | doc. Ing. Peter Buday, PhD., doc. Ing. Rastislav Ingeli, PhD.
The currently valid standard STN 73 0540-2/Z1+Z2, 2019 [1] defines thermal requirements not only for external envelope structures, but also for internal partition structures in residential buildings. These are defined by the thermal conductivity coefficient U (previously referred to as thermal resistance R) depending on the temperature difference between the rooms separated by these wall and ceiling structures. Based on a specific apartment in a prefabricated ZT building system, this paper quantifies the effect of this thermal insulation of partition structures (ceilings and walls) on the heat demand for heating (and thus its energy intensity) depending on the calculated temperature difference between the analyzed apartment and all neighboring apartments throughout the winter heating season.
