How is the slope protection foundation for oil storage tanks constructed?
Thread Content
The foundation design for a oil storage tank with a capacity of 1,000 cubic meters is as follows: the elevation from the bottom of the tank to the natural ground level is 0.85 m, and the foundation structure consists of a 45 cm thick layer of lime soil； 30cm sand layer ； 10cm asphalt layer. The vertical distance from the edge of the lime soil layer to the tank wall is 1.8 m. The drainage layer serves as a slope protection measure, and the design does not specify what will be used to enclose the foundation. Is such a design reasonable? How should it be constructed if it’s reasonable?
In my opinion, when conducting geological surveys, if the geological structure meets the requirements and the bearing capacity is sufficient for small storage tanks, then a slope-type foundation can be designed; in that case, there is no need to use anything to enclose the foundation. This design is reasonable, as your tank has only 1000 liters. The specific construction of the slope protection measures depends on the relevant specifications and the requirements of the design team. It is important to note that the slope protection work should be carried out only after the pressure test of the storage tank and once ground settlement has completed, in order to prevent cracks in the slope protection.
