Bishop Pore Pressure Apparatus for Civil Engineering from Laboratory Equipment Manufacturers India – This is as per the principals outlined in the book “Measurement of soil properties in triaxial tests” by A.W.Bishop and D.J.Henkel. This is used as an accessory for the triaxial test apparatus.
he apparatus consists of a panel for wall mounting on which are fitted -1.0 to 20 kg/cm2 x 0.1 kg/cm2 a pressure gauge, Bourdon tube type 20 cm dia.
Manometer: Glass U-tube manometer for measuring low positive pore pressures negative pore pressures and checking zero error of pressure gauge. It is provided with a mercury trap (Mercury supplied at extra cost). Null indicator made out of clear transparent perspex with mercury trap and cursor to indicate the mercury level.
Burette: 50 ml Burette for measuring the volume change in the soil specimen. Pressure pump fitted with four sleeves packed valves. Operated by mean of a hand wheel on the end of the piston rod which is threaded through the pump cap and gives a smooth, fine adjustment of pressure. Copper coil and water reservoir.
The unit is tested against leaks up to 10 kg/cm.sq
