The visualization of seepage flows trainer demonstrate and visualize the essential elements of fluid flow study. The educational unit is designed to illustrate an experimental study of flow through permeable media. The unit also allows the investigation of water pressure on structures.

                                     
  • The educational unit can be used to visualize streamlines in seepage and groundwater flow on different models using a different medium.
  • The unit also helps in studying the effects of water pressure on different structures Where they are displayed as pressure curves.
  • The trainer consists of a transparent tank filled with sand where various models can be placed in the sand bed to demonstrate typical structures.
  • The unit also contains a closed water circuit with storage tank and pump.
  • Adjustable overflows are provided close to each end of the tank so that constant water levels may be maintained in each half of the tank.
  • The unit allows the separation between the experimental section and the feed and discharge chambers by fine mesh screens.
  • The water supply is adjusted by a valve, and a contrast medium to make the streamlines visible, as they occur in seepage and groundwater flow.
  • The unit is distinguished by its glass viewing window which allows optimal observation of the experiments.
  • The educational unit is supplied with various models such as: sheet pile, retaining wall and foundation, these models allow an extensive range
  • of experiments, such as pressure distribution on retaining walls or seepage and groundwater flow under sheet piles.
  • The “foundation” and “retaining wall” models are provided with tubes to show the pressures on the models.
  • In the experimental section, there are measuring connections to detect groundwater levels, where the groundwater levels are displayed on 14 tube manometers.
