Claim 0:
1. A device for shoring temporary surface excavations, the device including:
(a) a base unit defining a base unit wall, the base unit wall extending in a height direction from a base unit lower edge to a base unit upper edge and having a base unit wall inner surface defining a volume of the base unit and a base unit wall outer surface facing way from the volume of the base unit, wherein (i) the base unit wall outer surface at each point along the length of the base unit wall in the height direction extends along the distance from the base unit lower edge to the base unit upper edge approximately parallel to a base unit central axis extending in the height direction, and (ii) the base unit wall outer surface defines the maximum dimension of the base unit along any line that intersects the base unit central axis perpendicular to the base unit central axis, and (iii) the base unit wall defines a barrier to the volume of the base unit in directions transverse to the base unit central axis;
(b) at least two jacking lugs mounted on the base unit and spaced apart about the base unit central axis, each jacking lug including a direct connection to the base unit wall inner surface and extending from the base unit wall inner surface in the volume of the base unit and each jacking lug further including a jack receiver positioned to receive an upper jacking force application element of a respective jacking device aligned to apply a jacking force in a direction from the base unit lower edge to the base unit upper edge;
(c) at least two lifting features mounted on the base unit and spaced apart about the base unit central axis, each lifting feature residing within the volume of the base unit and providing a lifting point adapted to accept a lifting force applied from above the base unit upper edge in the height direction; and
(d) a number of upper connecting elements spaced apart about the base unit central axis, each upper connecting element being proximate to the base unit upper edge.
