The large volume concrete of large-scale water conservancy projects is prone to cracking because of hydration heat, which would affect the safe and stable operation of the project. The author, taking Shushan pump station as an example, studies and introduces the construction of large volume concrete, temperature control and crack prevention technology suitable for the site. The results show that by layered and segmented pouring and installation of cooling water pipes, the coordinated optimization of temperature control, crack prevention and structural stability has been achieved, which has effectively reduced the risk of crack formation, ensured the construction quality of the project, and improved construction efficiency.
