Abstract: An elongate shoring device capable of supporting a high longitudinal loading with the ability to yield uniformly in a direction along the longitudinal dimension of the shoring device when the longitudinal loading on the shoring device exceeds a preset magnitude. The shoring device comprises an inner elongate tube which is received within an open end of an outer elongate tube for longitudinal, telescopic movement within the outer tube. A storage compartment having a variable volume is formed by the inner and outer tube when the inner tube is received through the open end of the outer tube, with the volume of the storage compartment decreasing as the inner tube moves in its longitudinal, telescopic movement into the outer tube. A solid, non-compressible material is contained in the storage compartment, and a relief opening is provided in communication with the storage compartment.
