Pullout Test Apparatus Applications

Laboratory pullout test apparatus is used for determination of pullout coefficient / coefficient of interaction between reinforcement (GI Strips, Geosynthetics, etc) and back fill material in RE walls. ‘Reinforced Soil’ technology involves inserting reinforcement (geosynthetics or GI Strips) inside earth fill during construction of embankment. To ensure that backfill earth and reinforcement act together as one entity, there must be enough mobilisation of friction between the earth fill and the reinforcement, so that ‘Pull out failure’ of reinforcement does not occur. This equipment is meant for measuring pull out resistance of soil reinforcement materials with different types of backfill materials. These results are useful for designing safe and economical reinforced earth structures.

Pullout Test Apparatus Instructions

• Use the actual backfill material which is proposed for the construction.
• Geosynthetic material strength properties and applied normal load should be intimated
• Approximately 4000 kg of backfill material and 30 m length of geosynthetic material / GI strip (in Numbers) would be required for testing

Details of apparatus

• Hydraulic Jack hand operated with separate pumping unit. The pumping unit is connected to the hydraulic jack by means of a flexible connecting pipe 5 meter long
• The jack is fitted with lifting handles for easy transportation.
• The approximate lift of the ram is 150 mm.
• The pumping unit is a single plunger type with detachable handle.
• The unit is fixed on a channelled base, which is fitted with lifting handles. A pressure release valve is provided on the pumping unit.
• The load is indicated on a 15 cm dial hydraulic pressure gauge of appropriate capacity, which can be detached from the pump when not in use.
• The least count of the calibrated dial will be according to the capacity of the gauge (Normally 100 divisions for full capacity).
• Capacity: 25 ton (250Kn)
• Supplied With Calibration Certificate.
