DEFINITION

Classification: 52/169.1

(under the class definition) Structure including a claimed feature of the earth or relationship to the earth, e.g., grade level, material between a wall and the earth, underground structures resisting external objects, position in the earth, etc.

SEE OR SEARCH THIS CLASS, SUBCLASS:

86+, for vertically curved arch with earth supported abutments.

102, for an earth supported type coping.

128+, for a shaft with diagonal earth engaging brace or guy.

155+, for a structure with earth piercing features. 167.1+, for a structure combined with means for compensating earth transmitted forces, e.g., earthquake.

274, and 292+, for a footing or footing combination.

741.11+, for a construction process utilizing the earth.
