METHOD OF ISOLATION OF MAP OF ACTUAL INDUSTRIAL WASTE DUMP Russian patent published in 2014 - IPC B09B1/00 

FIELD: ecology.

SUBSTANCE: for isolation of map of actual industrial waste dump the layered storage of landfill masses 1 is carried out, with an intermediate layer 2, and create a watertight barrier is made at the location of the base 11. At that the intermediate layer 2 is made in the form of multi-piece stabilising construction, for which on the landfill mass 10 the geogrid 3 is placed, a layer of broken bricks 4 of fraction of 20-40 mm with the capacity of 15 cm, a layer of contaminated sand 5 with a capacity of 20 cm, a geomembrane 6, a layer of contaminated sand 7 with the capacity of 70 cm with compaction, a geogrid 8, a layer of broken bricks 9 of fraction of 20-40 mm with a capacity of 50 cm. Storage of the subsequent landfill masses 1 is carried on the intermediate layer 2. The watertight barrier is created under the base 11 of the map along its perimeter by injecting a viscoelastic mixture 14 in the form of the polymer-loamy mixture through the perforation openings of the filter 13 of the horizontal wells 12 formed by drilling, in any of the angles of the base on two rays of this angle. At that the following angle for drilling the horizontal wells 12 is selected taking into account the possibility of injecting the polymer-loamy mixture on two or one ray to create a watertight barrier along the entire perimeter.

EFFECT: invention provides stabilisation of storage of landfill mass dumps, improving the insulating properties of the map base, simplifying the map isolation.
