Soil Permeability Apparatus

Soil Permeability Apparatus

---

The apparatus is used for the laboratory determination of permeability of soils using a constant or a variable head. This test is recommended for soils with co-efficient of permeability in the range of 10 x -3 to 10 x -7cm/sec. The maximum particle size of the soil which can be tested in the mould is 10 mm.

Technical Specification:-
Consists of gunmetal mould 100mm dia X 127.3mm height X 1000ml volume, with collar of 100mm dia X 60mm high and drainage base plate
Drainage cap, Metallic clamping ring, two porous stone for base and cap
Dummy plate, air release valve with a set of three glass stand pipes approx.6mm, 10mm, and 20mm dia X 1 meter length mounted on a wooden board, the end of the glass tube is serrated to connect rubber tube of 3 meter length with pinch cock.
Material for Construction Stainless steel
Gun metal Drainage base plate with a recess for a porous stone and with an outlet valve.
Metallic clamping ring.
Gun metal drainage cap (top plate with a recess for a porous stone and fitted with an inlet valve and an air release valve.)
Gun metal dummy plate to serve as a false bottom during compaction. Porous stone for drainage cap.
Porous stone for base plate. Set of glass stand pipes approximately 6 mm dia., 10 mm dia and 20 mm dia mounted on a wooden board.
Each glass tube is longer than 1 meter and has a serrested end at the bottom.
To read water head 2 Nos. meter scales are fixed between the tubes.
