A shoring support structure (3) comprising an outer tube (2) having a threaded region (22) with opposing longitudinal slots (16) and an inner tube (4) slidable within the outer tube and having a plurality of pairs of transverse holes (14) at spaced apart intervals. The inner tube and outer tubes terminate in a plate (6) and a pin (10) is receivable through the slots of the outer tube and a pair of transverse holes of the inner tube. A collar (8) is mounted on the threaded region and is rotatable to raise and lower the pin within the slots. The collar includes a driven member (30) such as a bevel gear for mating with a driving member (32) such as a pinion connectable to an actuator (38), actuation of the driving member causing rotation of the driven member to effect rotation of the collar (8) to move the pin.
