On the first period of using storage yards of combustion wastes collected big amounts of ashes and slugs transferred in pipes by hydraulic method. As a result of power plant operation in those time we have got a part of agriculture area with storage yards which are very large with embankments up to 20 m and sometimes higher. Space for accumulation of combustion wastes was enlarged in stages by construction of new sections of yards and embankments on settled wastes. Because of their sizes and safety conditions for surrounding such structures are similar to water storage reservoirs with earth embankments. Progress of technology in utilization of combustion products caused that amount of wastes collected in settling ponds now is much smaller than on beginning. A big part of ashes and slugs is transferred directly from power plant to mines in trucks and only ashes are folding in yards. In most cases folding of ashes is hold in sections of yard in such way that two or more often three sections are in operation. The first one is used for folding, second is filled with wastes for drying and material from the third one is transferred for ...
The article presents description of structures of embankment protection of Odra river and their significance analysis in the Wroclaw Water Junction. Creating of Odra river as an important European water route and related to this fact development of Wroclaw Odra section and a need of protection city of Wroclaw against flood caused appearance of many different structures of embankment protection according to their functions, constructions and building materials. Technical solutions are presented depending on flood protection, water management, inland navigation and recreation usage of Odra river. The experiences gained after flood in 1997 indicate that not all technical solutions protecting stability of water embankment meet standards of flood safety, duration and aesthetic features. Some sections of river embankments present bad condition. The need of preparing of optimization of repairing and renovation technology for different types of structures of embankment protection is emphasized. ...
