CHUTE FOR PASSAGE OF MUDFLOW

摘要

water-development works, prevention of intensive wear of concrete lining. SUBSTANCE: roughness arc-shaped in plan which can be subjected to relative stree-strain behavior caused by pressure of incoming mudflow on to upper edge is arranged on bottom of chute for passage of mudflow. All load of pressure of mudflow will be transmitted to abutments located in dips of chute which can be straight or laid. Roughness on walls of chute with rigid attachment that can be oriented either perpendicular or inclined towards direction of motion of mudflow is also provided. To impart structure with flexibility bottom roughness can be split in plan into individual members by means of structural deformation seams interjoined with the help of reinforcing cable which enhances stress-strain behavior of structure. EFFECT: reduced usage of concrete on dips and bottom of chute for passage of mudflow in process of its construction, prolonged service life of chute. 3 cl, 8 dwg
