It is a light weight aluminum derrick can be dismalted for ease of transport. The equipment is suitable for shallow soil sampling, lifting casing, standard penetration tests and lifting operations. Complete with upper tie bolt and ball but without sheave.

When conducting traixial tests on soil samples, it is observed that due to internal pressure, the cell expands, soil specimen consolidates resulting in the change of volume. Volume change Gauge is therefore deviced to accurately measure volume changes. This is measured by observing the quantity of water entering or leaving the cell as the cell pressure and axial load are changed it is achieved by the displacement of free surface between the water supplied to the cell and another fluid (paraffin or kerosene). A dye is added to the paraffin for clear demarcation of the interface. The unit consists of a glass graduated tube of the appropriate capacity graduated to parts of a ml.enclosed in a perspex tube sealed by two end caps. The unit is fitted with manifolds and valves which enables it to be used with the triaxial cell and the constant Pressure (Mercury controls) system. The cell pressure can either be directly applied to the cell from the constant pressure system or through the volume change gauge. The graduated glass tube is not subjected to any difference in pressure and its inside is coated with a layer f silicon water repellent to reduce the error in meniscus. There is an arrangement for filling the unit with water and paraffin and a drainage valve is provided in the lower end cap. The whole assembly is mounted on a panel suitable for wall mounting. The unit is supplied complete with a pressure hose with end couplings and a packet of dye.

Consolidation test is un-dimentional test considered extremely important in soil mechanics. Sample taken from adjacent areas of a single site show differential settlement even when tested using same techniques. Soil of similar strength may show varying consolidation. Samples are very carefully prepared and vertical settlement of the specimen in saturated or drained conditions carefully recorded when known load is applied.
