CASAGRANDE TYPE POROUS TUBE PIEZOMETER

Listing ID #4811257

Casagrande Porous Tube Piezometers
The top Porous Tube Piezometers Manufacturers, Suppliers from Roorkee, Uttarakhand. Casagrande type Porous Tube Piezometers are used for measuring and controlling pore water pressure in soil, rock and to monitor the construction control and stability in embankments, dams and reservoirs. A standpipe, with a porous piezometer tip connected at its lower end, is installed in a borehole. Bentonite and/or grout are used to seal the borehole above the "tip". The water level inside the "standpipe" is measured with the help of a Electronic water level Indicator, and corresponds to the water pressure at the piezometer elevation. Permeability of soil in the vicinity of the tip can be determined, when required, by increasing the water head in the standpipe, and observing its dissipation rate. Advantages - (a) Ideal fordermining the piezo-metric level during routine site investigation. (b) Can also be installed after the completion of construction & therefore suitable for use in existing dams/embankments. The wide demand of our Porous Tube Piezometers testifies its quality as well as performance levels.
