Abstract: Circulating water pump house open caisson of a larger thermal power plant is built on a 20~30m depth soft soil layer. Use cement mixing piles under the blade feet for controlling open caisson sinking, and pile cement mixing piles around the open caisson in case water and mud flow into the open caisson. Pump room ground treatment uses rigid pipe pile foundation treatment scheme, at the same time, uses lattice type cement mixing pile to protect pipe pile foundation. This paper introduces the design of large pump house open caisson and controlling sinking in deep soft soil layer in details. It could provide a reference for similar engineering and construction.
