| Automatic Compaction Machine. |
| |
|
| A mechanically cum electrically operated device is useful to eliminate the hand compaction procedure, which also considerably saves time with the rammers provided for both of the standard and heavy compaction of the soil. Useful for soil compaction into 100 mm or 150 mm Dia moulds.
Two sets of rammers are provided, one of 2.6 kg weight and arranged for 310 mm fall and the other one is of 4.89 kg and arranged for 450 mm fall. For compaction in 150 mm Dia moulds, there are 100 mm Dia rammers of 2.6 kg & 4.89 kg are provided and for compaction in 100 mm Dia moulds, there are 50 mm Dia rammers are provided. The rammer assembly is provided with ratchet and pawl arrangement to lift it from the top of the soil layer.
When the rammer reaches the required height, the pawl releases the rammer, which falls freely on the soil surface. An arm moving up and down operates the release mechanism, which is connected to a reduction gear coupled to the motor through another arm. An automatic blow counter is fitted to the compactor is used to set number of blows. The base plate of the specimen mould can be fitted to the rotating base plate of the instrument, which makes 1/5th revolution per stroke.
The equipment is suitable for operation on 230 Volts, 50 cycles, single phase and A.C. supply without moulds. |

Volume Change Gauge.
| |
|
| When conducting triaxial 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 developed 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 sided 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 enable 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 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. |
