MODERN TECHNOLOGIES OF WATERPROOFING OF IRRIGATION CHANNELS REVIEW

The article discusses the main types technologies of waterproofing of irrigation and melioration channels, hydraulic engineering, water management and nature conservation objects. Providing and waterproofing is the obligatory requirement at designing of new and rebuilding old channels. The purpose of channels (irrigation, industrial, drain est.) hasn't the meaning. Fundamental, theoretic and practical aspects of waterproofing waterworks are described in works many homeland and foreign scientists, but. The question of waterproofing irrigation channels, water management and hydraulic engineering objects are not closed. The facing of many irrigation channels is inefficient irrigational and has unreliable waterproofing. There are big filtration losses from irrigation channels which eventually lead to flooding of territory with damping of soil, on hidrogeological regime territory. The loss water capacity from channels reach big extents and can be about 60% from the total amount of water. Nov in modern construction and rebuilding of irrigation channels use geomembrane «Teranap» with exellent waterproofing characteristics under a layer of reinforced concrete whine will provide lasting protection. There are also the system of membrane «Tefond» whien has such types: Tefond plus, Tefond HP, Tefond drain, Tefond drain plus, Tefond plaster. The properties «Tefond plus» provide lasting waterproofing of bottom and sides of the channel due to double mechanic linking and double seals of edges. The material is simple in laying. Speed its using doing membrane «Tefond plus» the best decision to waterproofing of channels. Thus an analyses up to date materials and technologies using lasting waterproofing of irrigation channels, water management and nature conservation objects show high efficiency geomembrane «Teranap» and system «Tefond».
