FLEXIBLE CONNECTING STRUCTURE Russian patent published in 2005 - IPC

FIELD: hydraulic engineering, particularly connecting structure to prevent river or channel bottom erosion.

SUBSTANCE: structure comprises inlet, spillway and outlet, namely water apron, parts. The structure is flexible and made as a single whole. The structure comprises composite weir with ridge made of metal channel bar, flexible ferroconcrete upstream apron abutting upon the channel bar from upstream structure side and ferroconcrete downstream apron abutting upon the channel bar from downstream structure side. Upstream apron comprises mesh grid covered with high-strength concrete. Downstream apron is composed of one or two layers of mesh grid covered with high-strength concrete. Flexible ferroconcrete upstream apron is connected to weir at higher location than downstream one. The structure edges may be embedded in abutment. Ferroconcrete upstream or downstream aprons may be covered with wear-resistant material of natural stone or concrete panels. Ferroconcrete upstream apron may be deepened in direction from weir body. Ferroconcrete downstream apron may have reverse slope in direction away from weir body.

EFFECT: increased structure strength and resistance, reduced cost and labor inputs for structure erection.
