FOUNDATION PIER SYSTEM AND METHOD
摘要:
A concentrically loaded foundation pier system which includes several concentrically stacked steel pipes filled with concrete. The entire pier is installed centrally beneath the footing of the structure. Shims are placed between the top-most pier element and a pier cap which prevents shifting when the soil expands and contracts. The final structure is end-loaded and pressed to the bedrock or other load-bearing strata. An alternative embodiment includes a temporary lifting assembly which can be fastened about the structural pier without need for bolts or other fasteners.
