METHOD FOR WATER RETAINING STRUCTURE BUILDING, PREFERABLY IN CANYONS WITH SIDES OF WATER-PERMEABLE AND WATER-TIGHT GROUND LAYERS

摘要

FIELD: hydraulic building, particularly to build water retaining structure of in-situ materials.;SUBSTANCE: method involves forming structure body, which abuts channel sides, wherein channel sides define inclined planes and are flattened in areas near water retaining structure; arranging watertight barriers, drainage and slopes of lower pool sides; arranging drainage of upper pool side slopes; flattening canyon sides and forming ledges in water-tight layers of upper and lower pool layers; creating opened channels along ledge surfaces near slope bottom; forming manifolds along longitudinal structure axis in upper and lower pools; communicating opened channels in upper pool with side drainage; communicating opened channels in lower pool with side drainage and with structure drainage and connecting thereof with manifolds opened in canyon, wherein the channels are spaced from the structure so that the most dangerous side surface of manifold slope ground failure wedge is beyond the structure body.;EFFECT: increased reliability of water retaining structure due to prevention of structure base and lower slope damage as a result of ground motion and suffusion.;6 dwg
