METHOD OF IMPROVING DEVICE FOR IMPERVIOUS PROTECTIVE SCREEN ON MSW LANDFILLS Russian patent published in 2019 - IPC B09B1/00 E04B1/00 

FIELD: construction.

SUBSTANCE: invention relates to the construction and operation of landfills and landfills and can be used for the safe storage of waste and reducing their negative impact on the components of the environment. Method of improving the device of an impervious screen at MSW landfills is achieved with the right choice of location for the location of the landfill, taking into account the topography, characterized in that when creating a technological and technical design of landfills that prevent the penetration of pollutants into environmental components, the order of storage of solid waste is determined and the site is divided into several pits with a slope of at least 0.5 m, where the soil removed from the excavation is placed in cavaliers around the perimeter of the landfill with the difference in the level of the bases of the two adjacent excavations of 0.5–1.0 m, the foundation of the excavation is clay with a thickness of at least 0.5 m, with a filtration coefficient of more than 10–5 cm/s with a mandatory device of impervious screens made of geosynthetic materials (bentofix layer, carbofol layer, sacutex layer) with a covering layer of coarse sand 0.3 m, stored at the MSW landfill site are compacted by four or six passages of the bulldozer, forming a compacted layer on a work card up to 1.0 m high with intermediate insulation with soil, construction waste, slags with a layer of 0.15 m, preventing the spread of odors and the occurrence of fires, improving the appearance of the landfill with the mandatory conduct of quality control of stored waste and monitoring of the environment.

EFFECT: improving the safety of waste storage and reducing their negative impact on environmental components due to the construction or reconstruction of existing landfills and their transfer to a number of engineering structures.
