3 Overview

Oedometer soil compression test equipment. Consolidation apparatus according to the structure can be divided into leveraged and pneumatic oedometer oedometer (See Figure 1, Figure 2). Leveraged consolidometer principle axial pressure is applied on the soil sample weight by using a lever; Pressure Formula consolidation apparatus works by air pressure controls axial pressure is applied on the soil samples to determine the axial deformation of soil samples The relationship between pressure and deformation relationships of time, for the calculation of soil settlement units, compressibility, resilience Department Number, and compression modulus consolidation coefficient.
