PERMEABILITY TANK APPARATUS Model FM 44
PERMEABILITY TANK APPARATUS Model FM 44
Sci-tech Permeability Tank Apparatus Model FM 44 is mounted on a fabricated steel frame fitted with castors and leveling feet. The front, back and ends of the tank are of clear toughened glass giving scratch free visibility without the risk of abrasion of the inner surfaces by the permeable medium. The base of the tank incorporates fourteen pressure tapings at 100 mm pitch, the tapings are specially designed to prevent the ingress of sand particles. Flexible tubes connect the tapings to 14 tube multi-tube manometer bank scaled 0 to 500 mm, for measurement of the water table height along the tank. Removable end baffles are used to contain the permeable medium within the central part of the tank, thus providing inlet and outlet header compartments. A speed controlled centrifugal pump circulates water from a sump tank to either or both of these header tanks. Adjustable overflow pipes in the header compartments allow the hydraulic gradient across the various models to be adjusted. An open top enables easy access for setting up the experimental models and for filling the tank with the permeable material. A removable trap and sand chute are provided to allow convenient removal of the sand. Foundation model, sheet piling and simulated dam models are manufactured from opaque pvc sheet and are fitted with seals which seal against the front and back of the tank. A dye injection system allows four dye lines to be generated which highlights visualization of flow lines and allows flow nets to be drawn for seepage analysis. Scales on the front panel assist in the preparation of models. An activated carbon de-colorizing filter is provided in the sump tank to prevent the progressive dis-coloration of the water by prolonged use of dye. Scales on the front panel assist in the preparation of models and in the preparation and recording of flow nets. Washed silica sand graded 0.2 mm to 1.0 mm should be used as the permeable medium which must either be ordered separately or supplied by the end user. Coarser material may also be used.
