Construction Method for Forming Concrete Shear Keys at Vertical Construction Joints of Slurry Walls

지하연속벽 수직시공이음부에 콘크리트 전단키를 형성하는 시공기술

The shear connection of the vertical construction joint of a slurry wall by the concrete shear key has excellent structural performance and is economical and eco-friendly. However, technology for forming concrete shear keys in the underground is still underdeveloped. This paper proposes the development of the construction technology required to form a concrete shear key at the vertical construction joint of the slurry wall.
