MUDFLOW CONDUIT Russian patent published in 2003 - IPC

FIELD: hydraulic engineering construction. SUBSTANCE: mudflow conduit includes tray of polygonal section with symmetric slopes. Side slopes of tray are reinforced with relieving walls of stepped shape made of reinforced quarry-stone structure with reinforced concrete inserts. Reinforced concrete inserts are arranged over height of walls at some distance one from another, are strongly tied up to gauze anchors reinforcing ground mass behind walls. Bed slopes are reinforced with flexible reinforced concrete grillages placed sideways to section at some distance one from another. Grillages are made up of prismatic reinforced concrete blocks which upper faces are inclined and reinforced in opposition to direction of mudflow. EFFECT: increased efficiency and reliability of operation of mudflow conduit, raised transportation capacity, reduced usage of concrete for lining of slopes, prolonged se service life of mudflow conduit. 3 dwg
