RÉSUMÉ

The paper presents results of studies in mechanical properties, filtration characteristics, protective abilities, and structural properties of fibrous materials made of mineral or polymeric fibers; the latter are used as filters in horizontal, vertical, and radial drainage that protects cultivated lands, town territories, and particular objects from underflooding. Results are presented that were obtained by studying the drainage intake ability depending on the drain design, drainage construction methods, and properties of drained soil. A calculation procedure is suggested together with recommendations needed to design the drainage properly. The paper gives recommendations on technologies of construction of fibrous filters and drainage based on them, in various groundwater conditions and with various chemical properties of the water environment. Also, the extent of implementation and results of the long-term of field investigations are described; these demonstrate the efficacy of the new drainage designs, show their technical and economic efficiency in reclamation construction and various fields of water engineering.
