MR-S1 Drainage And Seepage Tank Educational Equipment Hydraulic Bench 1. Description The bed of the tank is made from painted mild steel. The sides of the tank are supported and sealed by a well proven method which allows free access to the interior and results in minimum sight obstruction. One side is of toughened glass to give good scratch-free visibility over a long period of use while the other is made of aluminium which permits the insertion of pressure tapping points as required. The ends of the tank are made of steel plate. 2. Typical student experiments include: ➤ Seepage underneath a sheet pile wall ➤ Seepage through an earth dam ➤ Control of seepage through permeable soils by sub-soil drainage ➤ Distribution of uplift pressure on hydraulic structures ➤ Reducing uplift pressure and lateral thrust by drainage ➤ Formation and behaviour of ‘Quicksand’ ➤ Stability of an earth dam ➤ Draining an excavation site using wells
