Experience in restoration of the spillway dissipator of the head hydroelectric station of the Chir-Yurt sequence

摘要

1.Operators should not violate the rules of operating gates established in designs on the basis of hydraulic investigations.2.An increase of the resistance of uplift and withdrawal of the apron slabs of the bottom of a dissipator should be achieved primarily by anchoring them to the foundation, which also saves construction materials.3.Protection of the surface of slabs and blocks of a dissipator from abrasion is achieved by placing on the slab surface a wear-resistant layer of high-grade, heavily reinforced, well-compacted and cured concrete prepared with strong crushed rock.
