| description | The utility model discloses a fully-embedded penstock structure on a downstream dam surface, and belongs to the technical field of hydraulic and hydroelectric engineering facilities. The fully-embedded penstock structure comprises a dam and a pressure steel pipe arranged in a reserved groove in the downstream dam surface, an outer-wrapped concrete layer is arranged between the pressure steel pipe and the dam, annular steel bars and vertical steel bars are arranged in the outer-wrapped concrete layer, and the side of the outer-wrapped concrete layer close to the downstream dam surface is exposed and superposed with the dam surface. The groove is reserved during construction of the dam, and the penstock is fully embedded in the groove with only one side exposed to ensure excellent cold-proof and insulation effect. The fully-embedded penstock structure combines advantages of the penstock on the downstream dam surface and the stability of integral embedded structure. The annular steel bars and vertical steel bars arranged in the outer-wrapped concrete layer outside the pressure steel pipe improve the toughness of the penstock on the downstream dam surface. Excellent damping performance is ensured, and the safety of the entire dam project is improved. |
