Jacking/scanning rig elements and functions

Part	Material	Description
A – Instron compression−tension plate	EN1A Steel	Fixture attaching part B to the Instron test frame. Features a central seating ridge and four through holes to secure with part B and allow for tension loading.
B – Testing pedestal	2024 Aluminium	Base plate for chalk specimen. Attached to A by four screws. Features a centred circular recess on bottom surface to improve coupling with parts A and H.
C – Specimen confinement	Perspex®	125 mm diameter × 5 mm thick and 120 mm high pipe casing for the chalk specimen. Attached to B by four screws.
D – Split-case pile confinement	6063 Aluminium	Guides pile during installation. Formed by diametrically cut discs with a circumferential groove and a circular recess on the bottom surface. Assembled using cable ties and fitted into part C (Figure 2(a)).
E – Model pile	Perspex®/PEEK	Cylindrical solid bar or tubular element (see Table 1).
F – Pile head insert	EN1A Steel	Inserted at the head of tubular pile to prevent damage by the grub-screw grip of element G. Features a longitudinal through-hole and a groove on the top surface as air-release.
G – Pile head grip Instron fixture	EN1A Steel	Element attaching the pile head to the Instron crosshead by way of four grub screws.
H – Scanning pedestal	6063 Aluminium	Replaces element A during XCT scanning. Features a central seating ridge. Attaches the rig by way of part B to the XCT scanner rotating stage while providing an offset distance from it to prevent image artefacts.
