The elbow passageway intake and straight tube outlet are used in Tai'erzhuang pump station. It is a typical space curved surface structure with the characteristics of big scale template,complex shape and volume,complicated construction technology,and difficult quality control. In order to control the construction quality, inside formwork was taken as key control link; sandalwood formwork was designed and fabricated; Electronic Total Station was used to determine position; and the jack was used to take accurate place for inside formwork. The inside formwork was strengthened,and the space size and surface smooth level degree are controlled. The purpose of Bao-Li Paper boards mould was used to increase the smooth level degree, while roughness of passage was decrease. The comprehensive technical including concrete curing and temperature observation was used to prevent concrete temperature crack validly. It is indicated that design of elbow passageway of Tai'erzhuang pump station was achieved design purpose for its super flow.
