Embodiment Construction

[0028] see Figure 1 to Figure 9 , The infiltration and seepage simulation experiment device of this embodiment includes a water storage tank 2 with a water pump 1 and a simulation box 3 with a horizontal bottom plate. The simulation box has a water supply chamber 5 containing a water supply hole 4, a simulation chamber 6 with an aquifer, and a drainage chamber 8 containing a drainage hole 7. Water-permeable mesh plates 9 are respectively arranged between the simulation chamber and the water supply chamber, and between the simulation chamber and the drainage chamber. The overflow return cavity 12 outside the overflow tank in the fixed head overflow tank 11 with overflow tank 10 at the upstream end of the simulation tank has an overflow hole 14 communicating with the water storage tank through an overflow pipe 13 . The water inlet 17 and the water outlet 18 communicated with the water storage tank water pump and the water supply cavity by pipelines 15 and 16 respectively are a...

Abstract

The invention discloses a simulated experiment device of infiltration and seepage which comprises a simulation case with a water storage tank and a horizontal soleplate; a water-supplying chamber, a simulation chamber with a water-bearing layer, and a water drainage chamber are arranged in the simulation case; an infiltration device arranged at the top of the simulation case is installed in the simulation chamber; an infiltration case with an infiltration rain fall plate at the bottom and an infiltration liquid supplying case positioned at the top of the infiltration case are arranged in the infiltration device, and the top of an infiltration liquid pipe located in the infiltration case is communicated with the bottom of the infiltration liquid supplying case; a tracer injection case is arranged at the top of the simulation case and at the upstream end of the simulation chamber, and the tops of at least three tracer control pipes positioned in the water-bearing layer of the simulation chamber and provided with control valves are respectively communicated with the bottom of the tracer injection case. The invention with a reasonable structure provides intuitive information on the physical process that water infiltrates the ground surface to supply the ground water, the ground water recharge method, seepage characteristics of steady movement of ground water, in order to conduct the relevant experiment and parameter measurement.

Description

Technical field: [0001] The invention relates to hydrogeology, in particular to an infiltration and seepage simulation experiment device. Background technique: [0002] infiltration of surface water; [0003] Surface water infiltrates along the gaps of rock and soil under the combined action of gravity, molecular force and capillary force, and its movement process is to seek the comprehensive balance process of various forces. The entire physical process of infiltration can be divided into three stages: seepage, seepage, and infiltration according to the combination of force changes and its movement characteristics. Experiments have found that when the rising height of capillary water is balanced with the downward penetration force of infiltration water, water cannot penetrate into the aquifer but migrates to the discharge boundary along a certain height above the water table. When the downward penetration force of infiltration water is greater than that of capillary water ...
