Description

Hi ,

I am designing a block foundation (Rotary type - 1500rpm) for the cement plant, in which i am having the allowable SBC as 60T/m2 at 3m below the NGL.

The block foundations are located inside the main building which the building foundations are designed for 3m below NGL. Hence i proposed to take the block foundation to the same lvl. Now my query is shall i provide a block for 1.5m bepth & for remaining 1.5m as P.C.C. The soil SBC is almost seems to be Rock ... so whether the assumption will bo o.k.

Note - As per the soil report i am having the Cu as 13.1kg/cm3 & E as 3428kg/cm2.

Kindly suggest me.

I think there is no need to take depth of block to the depth of foundation of building untill the equipment is not adjacent to column.
