INDUSTRIAL WASTE DISPOSAL AREA Russian patent published in 2005 - IPC

FIELD: hydraulic structures, particularly structures for burial storage of industrial wastes.

SUBSTANCE: waste disposal area has primary flood-breaking dam arranged at waste disposal area base and forming the first layer thereof and secondary dams. The secondary dams are mainly arranged on alluvial beach and form the next layers of waste disposal area. Drain is formed along the secondary dam. One or more secondary dams are provided with apron covering alluvial beach and drain is formed on the apron. Several secondary dams may be provided with short or long aprons. Short and long aprons alternate in each layer along waste disposal area height. Drain is located on each long apron. Apron may be formed of ground material having permeability coefficient K_a defined as K_a<0.2K₀, where K₀ is permeability factor of alluvial beach waste. Waste disposal area may have shield formed at waste disposal area base and including drainage layer covering shield part abutting the primary dam. Drainage layer is provided with drainage pipe and has width, which exceeds length of the secondary dam apron. Waste disposal area may include several layers. As number of layers increases ratio of long and short apron lengths decreases. Drain may be formed as drainage belt and provided with drainage pipe.

EFFECT: increased structural reliability and reduced costs.
