Permeability basin to clearly show the flow phenomena in permeable media, to visualize the flow lines, to build sheet pile curtain models of building foundations and to simulate dams. Autonomous equipment allowing a wide range of experiences.

This teaching equipment makes it possible to carry out the following practical exercises:

Determination of infiltrations under a structure

Construction of flow grids and determination of the permeability index

Sheet pile flow and determination of the critical infiltration force at which the ‘fox phenomenon’ occurs

Infiltration under a permeable dam

Flow under an earth dam with and without foot drain

Folding in horizontal flow (simulation of an underground water flow in a river or a source)

Determination of bearing pressures on structures such as building foundations

General studies on infiltration and drainage.

Flow through porous media (Darcy’s law)

Technical Specifications:

Basin with transparent front, mounted on a steel frame also supporting a work table

Basin sides equipped with glass plates resistant to abrasion of the permeable medium.

Compartments at the ends of the pool equipped with adjustable overflow pipe system to adjust the water level.

The top of the pond will be open to allow students to fill the tank and install structural models

Transparent, airtight plates to allow students to build models of walls, sheet piles and dams.

Around the front wall of the pool will be placed graduated scales to help students position and measure the flow correctly.

The rear of the basin will contain 14 pressure taps connected to piezometric tubes to measure the distribution of the load along the tank.

Removable deflectors with stainless steel mesh at each end of the basin

Supplied with a dye injection system to visualize the current lines.

Dimensions of the basin: 1500 mm x 550 mm x 180 mm

Dimensions and weight: approx. 2450 mm x 700 mm x 1500 mm and 230 kg.
