Grain Bin Foundation Failure and Recovery Case Studies
Ram Jack Stabilizes Converted Steel Grain Bin
Over 15 years ago, primary manufacturers of livestock feed and suppliers
of plant food and crop protection products, MFA Incorporated ran into
problems with the placement of a large grain bin on soil not sufficiently
compacted to withstand the weight of the steel bin.
The soil beneath a 50-ft. diameter steel grain bin began settling on one
side as a result of the soil not being sufficiently compacted to properly
support the steel bin. The quarter-inch steel was settling on the grade
and needed stabilization.
The major concern for MFA was the strength and integrity of the steel
grain bin with pilings beneath it. Ram Jack Mid Missouri recently attended
a geo-tech seminar about the effects of the shear line of soil on the
lifting of a structure: Unexcavated dirt would shear at a 45-degree angle
up and away from the structure. Ram Jack worked with the MFA engineer
and designed a plan that would strengthen the bin with the installation
of pilings. Vertical wide-flange beams would be attached to the bin every
six feet, attaching the pilings on a plated bottom. (19) 2 3⁄8 in.
helical piles with side-load brackets would be used in conjunction with
Ram Jack's calculated placement for maximum pratical recovery.
The project was completely successful. Ram Jack installed piles to an
average depth of 36 ft. and locked at 3,300 ft.-lbs. No stress was caused
to the bin, and it has stood with no problems for the past 15 years. Thinking
outside of the box, one can often find solutions for customers. MFA Incorporated
has remained a faithful customer of Ram Jack since the completion of this
