Abstract:

The intensive civilization development implies searching for new possibilities connected with extension of city agglomerations, both the areas of flat building and the industrial areas. One of the most interesting solution is to use water reservoirs, rivers and sea areas. The extension of buildings affects the building materials, especially hydrotechnical concrete. Water structures are usually the objects of huge dimensions exposed to extreme conditions. In most cases these buildings are specific and complicated. They require an individual approach to concrete mix design and should be monitore

Abstract:

Abstract A hydrotechnical structure is a structure with devices and technical installations related to them, used for water management and shaping and using water resources. Special attention should be paid to the properties of the used materials, but also to the impact of water and all accompanying processes. Over the years, geosynthetics are increasingly used as a material in construction, including hydrotechnics. The priority aspect when choosing a geosynthetic material is the approach to fulfilling a specific function, reducing investment costs, ensuring stability and strengthening the str

Abstract:

Hydrotechnical constructures are complex structures that represent the interaction between soil-, water-and technological environment. For trouble-free and safe operation of hydrotechnical constructures, as well as maintaining them in operational mode, by the operating organization, as well as by organizations that conduct technical supervision, constant technical inspectionsare carried out to fix the damage (defects). This allows you to determine the actual technical condition of structures.Currently, building information modelling (BIM) methodology is most widely used for modelling structure

The main material of the hydrotechnical structures of the water management and reclamation complex is concrete. Its durability is the main indicator of reliability of building operation. The high density of hydraulic concrete, which determines the water resistance, is a guarantee of its durability. At the same time, in hydraulic concrete during the operation under the influence of aggressive environmental factors various defects (cracks, dissected zones)develop, which reduce its waterproofing capability. These defectsare the main centers of water filtration through building structures. A

It was found that due to high plasticity, low porosity and the ability to quickly gain strength, polymer concretes are used for the manufacture of decorative products of small architecture, structural load-bearing and decorative overhead parts, decorative paving tiles and paving stones, products for hydrotechnical purposes, etc. by methods of vibration molding and casting. The classification of polymer concretes used in modern construc

Abstract:

The main problem in designing the discharge of water flow from the upstream to the downstream is to ensure the capacity of spillway structures. This article discusses the design options for the design top of the spillway: with water diversion through a short nozzle in the pressure mode and energy dissipation in stilling basin, with the pressure-free and pressure-free passage of water through spillway No. 2 and damping of the flow energy by jet discharge into the lower stream by the inclined face of the threshold in the stilling basin; with no pressure passage and pressure passage of water thro

The aim of the study was to determine the capacity of a selected section of the Sanna river, designated below the lower site of the weir in Zaklików. The capacity calculations included the conditions of flood water discharge, i.e. the reliable flow and the control flow, determined in accordance with the Regulation of the Minister of the Environment on technical conditions that should be ensured for the hydrotechnical structures and their locations. The paper presents the consequences of changes in the regulations regarding the determination of building type, for which reliable flow and control

Increasing water demand, combined with unfavourable climate change, creates a need for well-thought-out water management. Such goals are realised thanks to appropriate hydrotechnical infrastructure, the efficiency and functionality of which depend on its technical condition. In the literature, there is no method for the assessment of the technical condition of small damming structures, including sluice gates. The aim of this article was to present the possibility of using the multi-criteria AHP decision support method to assess the technical condition of small damming structures. The assessmen

Abstract:

River restoration projects rely on environmental engineering solutions to improve the health of riparian ecosystems and restore their natural characteristics. The Kwacza River, the left tributary of the Słupia River in northern Poland, and the recipient of nutrients from an agriculturally used catchment area, was restored in 2007. The ecological status of the river’s biotope was improved with the use of various hydraulic structures, including palisades, groynes and stone islands, by protecting the banks with trunks, exposing a fragment of the river channel, and building a by-pass near a defunc

Among the basic forms of monitoring in such facilities one should list continuous seasonal piezometric measurements, which are obligatory elements of general control measurements aimed at ensuring safety when using the facility. The latter is directly related to guaranteeing the safety of people living and working in an area exposed to destruction in the event of a possible disaster involving the building. From the pers

Speaking justly, they have an important socioeconomic role. Among the negative effects of longitudinal connection interruption of water bodies we can mention, the risk of not achieving the positive ecological potential of water bodies in accordance with the Water Fram

The assessment of the possibility of using incinerated municipal waste, which is classified as non-hazardous, is a priority of the European zero waste strategy. The aim of this work was to identify the properties of slag and ash to develop a simple, targeted way of using post-process waste. The material was analyzed by microscopic methods in terms of composition and internal structure. Gas and water permeability tests were carried out. Slag and ash texture was obtained using densimetric methods. BCR sequential extraction was carried out to assess the impacts of the waste on the water and soil
