The structure of large-scale shaft tubular pumping station is complex, the structure and size of each pouring block are different, and the temperature control index is also different. Especially in summer construction, it is very difficult to control temperature and prevent cracks. For different structural parts, refined peak clipping strength index should be adopted. In this paper, the equivalent cooling algorithm was used to simulate the peak-cutting intensity of cuboid pouring block under different water pipe layout, water temperature and water flow rate with different hydration heat inhibitor dosage and without hydration heat inhibitor. Then a series of quantitative formulas were put forward. According to the dosage of hydration heat inhibitor and peak-cutting intensity index, the layout density and water flow rate of cooling water pipes with corresponding water temperature can be calculated with these formulas. The results can provide quantitative reference for the establishment of temperature control measures for similar pumping stations constructed in high temperature season.
