BURIED WASTE STORAGE AND METHOD OF ITS CREATION Russian patent published in 2012 - IPC B09B1/00 

FIELD: process engineering.

SUBSTANCE: storage comprises regional confining layer, said layer there above, at least one layer of loam and/or clay sediments making sorption (filtration) shield above sand layer, system of horizontal tubular drains fitted in sand layer along storage edges to extend to pits for possible feed of filtrate to surface. Proposed method comprises selecting regional confining layer proceeding from hydrogeological data on estimates of flows over refining layer, analysing engineering survey of soil stratum section town to refining layer to reveal shielding and filtering layers at future storage bed and excavating soil to reach, at least, one pillar of loan and/or clay beds making a natural sorption and/or filtration shield. Note here that, additionally, cuts in pillar are exposed along pit edges down to sand layer under lower filtration layers for laying horizontal drains along pit edges and mounting pumps therein.

EFFECT: decreased costs.
