Material Stored: Cement
Silo Size: 27' diameter by 110' tall
Issue: Potential roof collapse
Pictured above is a silo beam pocket, the beam rests on a bearing plate and supports the roof slab. This situation was found during a regular inspection of the silo structure. Beam pockets are a critical point on the silo as they support the roof slab and all the necessary equipment to operate the bulk storage system. The beam end sits on the thick, steel bearing plate, however, the concrete under the plate is spalling leaving this beam pocket at risk for failure. This particular pocket has been cleaned and drilled to receive the required steel reinforcement per professional engineer instruction.
The spalled area above has the engineered solution to reestablish the structural integrity of the beam pocket. First, the roof beam must be lifted off of the beam pocket and bearing plate to allow for repairs. Once this is accomplished, repair work can commence. Structural steel is placed per engineer specifications to ensure the integrity of the repaired beam pocket.
Lastly, a high strength, non-shrink grout is used to patch the spalled area. After the non-shrink grout has properly cured, the roof beam can then be lowered back into position on the bearing plate. Once the pocket is repaired, the silo roof is structurally sound and safe for use.
