HYDRAULIC FILL SECTION FOR INDUSTRIAL WASTE STORAGE Russian patent published in 2005 - IPC

FIELD: hydraulic building, particularly facilities to store industrial waste.

SUBSTANCE: hydraulic fill section includes primary dam formed on base of the section, secondary dams and drainage system arranged in the base. Major part of each secondary dam is located on alleviation beach.

At least one secondary dam is provided with apron, which covers alleviation beach. Apron has drain hydraulically communicating with draining branch of drainage system through additional water pass formed in waste arranged in the section. Drain may be formed as drainage belt and provided with drainage pipe. Draining branch may be of tubular type and arranged in trench. If water intake chamber of drainage system is located in spillaway well section water intake chamber may be arranged under the spillaway well and have common body with foundation thereof. In this case discharge water channel may be combined with discharge manifold of spillaway well and maintenance passage is formed inside above manifold.
