【 摘 要 】

Based on the analysis of the concrete construction of the bottom slab of flood-discharge and sand-wash sluice in Angu Hydropower Station, this paper expounds the construction characteristics and difficulties, construction procedures, concrete construction of concrete stilling pool in conventional position, concrete construction of overflow and retaining wall, concrete construction methods and measures in special position, etc. Especially, the concrete stratified partition of the bottom slab of flood-discharge and sand-wash sluice and the typical partition of stilling pool have their unique features. The overflow surface concrete adopts self-designed, processed and manufactured stereotyped drawing dies. And after concreting, we use bamboo springboards and protective measures to keep warm in time. The construction scheme is reasonable in design, meets the requirements of construction progress, has no safety accidents, and achieves good construction effect. It has certain reference value for the concrete construction of bottom slab of flood discharge and sand washing sluice of similar projects.
