Abstract
A metallic piling sleeve member filled with solidified or cured cementitious material and a hollow, cylindrical outer sleeve member having a diameter larger than that of the metallic piling sleeve member are provided. The outer sleeve member is placed generally concentrically around the piling sleeve member and the piling and outer sleeve members are vertically driven into the soil. Further metallic piling sleeve and outer sleeve members are successively vertically driven into the soil until the piling is complete and the metallic piling sleeve and outer sleeve members abut one another in vertical relation.

A method of forming a foundation piling, the method comprising the steps of:
- providing a metallic sleeve member filled with solidified cementitious material;
- providing an outer metallic sleeve member having a diameter larger than that of the metallic sleeve member;
- placing the outer metallic sleeve member generally concentrically around the metallic sleeve member;
- simultaneously vertically driving the metallic and outer metallic sleeve members into the soil;
- and
- repeating the foregoing steps until the piling is complete, with metallic sleeve members abutting one another in vertical relation and outer metallic sleeve members abutting one another in vertical relation.
A method of forming a foundation piling in soil, the method comprising the steps of:
- a) vertically driving a cylindrical, metallic piling sleeve filled with cured cementitious material at least partially into the soil;
- b) vertically driving a hollow, cylindrical, metallic outer sleeve into the soil around and generally concentric with the piling sleeve member;
- c) abutting the outer sleeve with a second, similar outer sleeve;
- d) abutting the piling sleeve with a second, similar piling sleeve;
- e) vertically driving the piling and outer sleeves into the soil;
- and
- repeating steps a through e until the piling is complete.
A method of forming a foundation piling in soil, the method comprising the steps of:
- a) vertically driving a cylindrical, metallic piling sleeve filled with cured cementitious material at least partially into the soil;
- b) vertically driving a hollow, cylindrical, metallic outer sleeve into the soil around and generally concentric with the piling sleeve member;
- c) abutting the outer sleeve with a second, similar outer sleeve;
- d) abutting the piling sleeve with a piling drive member;
- e) vertically driving the outer sleeve, piling sleeve, and drive member into the soil until the piling sleeve is fully submerged and the outer sleeve is partially submerged;
- f) removing the piling drive member;
- g) abutting the piling sleeve with a second, similar piling sleeve;
- h) abutting the outer sleeve with an outer drive member;
- i) vertically driving the piling sleeves further into the soil until the second sleeve is partially submerged;
- j) removing the outer drive member;
- repeating steps b through h until the piling is complete;
- and
- capping the completed piling with a piling cap that distributes load over the outer sleeve, the piling sleeve, and the cured cementitious material.
