Research on Key Technology of"Full Pipe Group"Warehousing in Dahuaqiao Hydropower Station
The slopes on both sides of Dahuaqiao dam are steep,and the width of bridle path is narrow,so conventional warehousing methods cannot be used.Through the study of the actual terrain,the project technicians carried out the warehousing planning research in the form of full pipe group.A dam section is first poured on the dam crest of the left and right banks as a full pipe receiving platform,which effectively solves the technical problems of warehousing at the bottom of the left bank and warehousing at the gap through the form of full pipe+belt conveyor+full pipe.At the same time,the technical achievements of full pipe application at the right bank with a length of nearly 100 meters and a gap height difference of 45m are achieved.
