Order Catalog


The Model 4820 Jackout Pressure Cells are used to measure earth pressures on slurry walls. They are designed to fit inside a plate which is pressed against the side of a slurry wall excavation using a hydraulic jack arrangement. This method of installation ensures that the jackout cell is located with its sensitive face in contact with the adjacent soil. The two photos at right show the Jackout Pressure Cell separately, as removed from the assembly, and the complete Jackout Pressure Cell Hydraulic Jack Assembly (with piezometer installed to measure pore water pressures).
