Skuteczność odwodnienia wgłębnego metodą wiertniczą przy stabilizacji osuwisk
(2008) Bosak, Jacek; Bosak, Marek; Michalski, Tomasz
For already twelve years, authors, use landslides deep dewatering drilling method. Hereby, they would like to present its efficiency basing on some examples: Koronowo, Uherce Mineralne, Korytniki, Tyrawa Wołoska, Jarosław. Its main advantages are: water be interception before reaches the sliding area and executing dewatering works without negative influence on road dams and road traffic. Additionally, the sliding surface and colluviums are being dewatered. Method range is limited by the drilling technology only. Authors were installing horizontal drainages up to the length of 40 m. Drainage pipes being used have the specific construction: flexibility, high permeability (over 10%) and increase tensile strength. Entire problem is shown with the hydrogeology of the landslides area background. Authors are concluding, that using described technology, additional retaining structures are needed only for the road pavement restoration purpose and give additional safety factor. Each example project shows such structures.

The condition of streets in winter is the cause of many accidents with cars and pedestrians. One of the solution to prevent this type of situations is the warming of the streets surface, so that the snow and ice can’t gather on it. These installations are very expensive when the source of the heat is the electricity. Some countries, however, have found a way to use the underground geothermal waters (and rock mass) as a warmth collector. The master’s thesis contains examples of different technologies and solutions that were used in some countries in the world and in Europe. These examples contain descriptions of weather and geological conditions of the specific area, costs of the investment and exploitation. These examples were the basis for proposition of a similar application in Poland in the areas with good geothermal conditions and long winter season, which can be an innovative way of keeping streets, parking lots and sidewalks during winter. There is also information about the positive influence of these applications on the environment, economic and social advantages as a result of proper use of the geothermal heat..
