METHOD OF STOCKPILING WASTES INTO ACCUMULATOR Russian patent published in 2012 - IPC B09B1/00 

FIELD: process engineering.

SUBSTANCE: invention relates to power engineering and utility plants and may be used for non-polluting stockpiling of various wastes. Horizontal piezometer is arranged at accumulator foundation. Then, dam is dumped. Cell-like forms are arranged on foundation surface to be filled with ash concrete. Thus, anti-filtration ash concrete shield of foundation is produced. Ash concrete shields are made on inner slopes of said dam by laying ash concrete bulk in layers. Then, gas-escape drainage is installed on anti-filtration shield to be built up as accumulator comes filled layer by layer. After dumping next layer of wastes, intermediate ash concrete layer is dumped thereon. Waterproof shield made from ash concrete is created on the surface of filled accumulator to be covered by soil reclamation layer.

EFFECT: improved environmental conditions.
