METHOD OF COLLECTING AND DISCHARGING BIOLOGICAL GAS FROM SOLID WASTE POLYGON Russian patent published in 2008 - IPC B09B1/00 B09B3/00 

FIELD: disposal of solid domestic waste.

SUBSTANCE: method comprises preparing base, assembling system of vertical draining made of a set of wells distributed over the polygon and made of sections provided with perforated walls, applying waste in layers, extending the walls at a height of each waste layer with the use of sliding box, plugging the top ends of the well during each extending cycle, and discharging biological gas from the vertical gas drain through the horizontal pipelines mounted in the polygon base. The bottom sections of the vertical wells are solid and connected with the drain wells of the horizontal draining pipelines. The top end of the bottom section of the vertical well is positioned above the level of the filter and filtering protecting shield. The joints between the sections are made for permitting them to move and to be positioned at various angles one with respect to the other. The wells, pipes, and joints of the horizontal and vertical drain are made of anticorrosion materials, e.g., fiber glass-reinforced plastic.

EFFECT: improved environmental protection.
