During experiment, fill the sand or the soil of different-grain diameter, grating as required in the bottom of emulation sluice sectional model, inject enough water gagings in reserve tank, the switch pump of fetching boiling water makes seepage flow formation Automatic Cycle in the sluice foundation.Simultaneously, the special use that has the automatic colour killing of time-delay, is difficult for diffusion, does not pollute sand, is different from the sand color easily of packing in advance in showing the liquid box shows liquid.After forming stable self-loopa in the instrument, show that liquid shows liquid by conduit above-mentioned characteristic of input under the base plate of emulation sluice sectional model upstream, can show the seepage flow phenomenon intuitively.
For making upstream water inlet similar to actual seepage flow, show more intuitively, the utility model is provided with permeable hole at the upstream and downstream end of the sluice plate of emulation sluice sectional model.
For forming the seepage flow under the steady flow, the utility model is provided with the water-stabilizing board in the steady pond of permanent head, the last uniform water aperture of crossing of water-stabilizing board, and the water inlet pipe port arrangements that is connected with water pump is in water-stabilizing board's the outside, upstream.
In addition, the utility model emulation sluice sectional model cross water direction width less than the steady pond of permanent head width in the same way, purpose is perfect more in order to show the seepage flow streamline, makes demonstrative process more clear, the convenient use.
For ease of observing, the sidewall of emulation sluice sectional model is made with transparent material in the utility model.
For the ease of seepage flow streamline (wire harness) under the different sluice plate structural conditions of paired observation, the utility model emulation sluice sectional model is divided into two lock chambers, has sheet pile for seepage control at the sluice plate of a lock chamber.
