Over-current slag collecting weir for water conservancy and hydropower engineering and construction method thereof
The invention discloses an over-current slag collecting weir for water conservancy and hydropower engineering and a construction method thereof, and belongs to the technical field of water conservancy and hydropower engineering building design and construction. According to the over-current slag collecting weir for the water conservancy and hydropower engineering and the construction method thereof, the building slag collection is convenient, the structure is simple, and river channel sedimentation can not be caused. The over-current slag collecting weir comprises an over-current weir body and an over-current protection structure laid on the outer side of the over-current weir body. The construction method comprises the steps that firstly, rock ballast and riprap are thrown and filled in a natural river channel to form the over-current weir body; secondly, transition layer ballast materials and bedding layer fine slag materials are filled on the surface of the over-current weir body; thirdly, loose-stone revetment is constructed on the upstream side of the over-current weir body, and geotechnical cloth is laid at the weir top and on the downstream side and a slope toe platform of the downstream side; fourthly, a flat concrete section, a dam top watertight concrete section, a slope toe platform concrete section and a guard pile and connecting beam slab of the slope toe platform concrete section are poured; lastly, reinforcement gabion permeable erosion protection pressing bodies are constructed to complete the construction work of the over-current slag collecting weir.
