GROUND SHAFT INCLUDING SIDE WALLS CONFIGURED TO PROVIDE ENHANCED LOAD-BEARING CAPACITY
20240376681 · 2024-11-14 · ·

A frame portion may be configured to provide enhanced load-bearing capacity for a ground shaft that is configured to delimit a cavity. The frame portion may include a first longitudinal wall portion and a second longitudinal wall portion, and a first lateral wall portion and a second lateral wall portion configured to be coupled with the first longitudinal wall portion and a second longitudinal wall portion. At least a portion of the first longitudinal wall portion may comprise plastic. The first longitudinal wall portion may include a tensioning portion structurally configured to counteract a deformation force acting on an exterior side portion of the first longitudinal wall in a direction toward an interior of the frame portion so as to enhance load-bearing capacity of the first longitudinal wall portion.
