Wudongde Arch Dam

As the world's seventh-largest hydropower project under construction the Dam of Wudongde hydropower station is the world's thinnest double curvature arch dam among dams with height of approximately 300m.

Challenge:

• complex geometry

• small curvature radius of a parabolic shape

• straight and twist block joint in different elevation

• strong windy weather on site

• low heat cement concrete application

• high casting height of 4.5m

Solution:

• Curved Top50 large area formwork to fit the structure shape with high precision

• Hydraulic self climbing D35 dam formwork along double arched structure surface in strong windy weather

• Full planning climbing tracks to meet the structure change
