DEVICE FOR STORING WATER-CONTAINING WASTE Russian patent published in 1998 - IPC

FIELD: hydraulic engineering. SUBSTANCE: this is intended for dumping and storing of water-containing waste in basin of worked-out rock quarry. Basin bottom and sides have zone of increased fissuring with open fissures. Entrance to open fissures is closed by water unsurpassable barriers. Made in basin bottom is drainage system. Water branching main line is made in the form of perforated pipe located on bottom of trench which crosses entire fissured zone and which is filled with loose filtering material forming water-catching vertical drain layer. Main line of drainage is also made in the form of tunnel located below zone of high fissuring of rock together with water-catching radial drain bore-holes. EFFECT: high efficiency. 2 cl, 2 dwg
