  • 30 Foot chamfered deadman
    Publication number: 20080101864
    Abstract: The invention provides a long steel reinforced concrete deadman with superior strength for anchoring underground storage tanks (USTs). Reinforcing steel bars about 0.88 inches in diameter provide an advantageously high ultimate flexural strength capacity for a concrete deadman. Among the advantages offered by high flexural strength is the ability to use a longer deadman about 30 feet or more in length, which simplifies installation of USTs, especially in a flooded hole.
