Abstract: The intake tower project of water plant in Baihetan Hydropower Station on Jinsha River has complex structure, large concrete pouring volume and high construction difficulty. Considering the high-quality engineering standards, the forming quality of concrete is demanding. Due to various adverse factors such as long time consuming, difficult quality control and poor integrity, it is difficult to realize the quality control with traditional combined steel formwork layered construction. In the water plant of Baihetan Hydropower Station, a new slipform system was designed, and the system scheme design, implementation steps and process control points were introduced in detail. The practice showed that the new slipform system solved the once-molding quality problem of mass surface concrete, shortened the construction period, saved the cost, and ensured the smooth operation of the water supply system. Relevant experiences can provide reference for similar construction projects.
