Fig. 2 is experiment table stage body master TV structure figure of the present utility model.
Fig. 3 is experiment table stage body plan structure figure of the present utility model.
Among the figure: 1-experiment table table top, 2-crack passage, 3-by-pass valve control, the 4-flow sensor, 5-pressure transducer, 6-gaza funnel, the 7-water pump, 1-1. experiment table stage body, 1-2. poly (methyl methacrylate) plate, 1-3. rubber gasket, 1-4 prefabricated crack piece, 1-5 crack water flowing interface, 1-6. screw, 1-7. nut, the 1-8. sand inlet.
Embodiment
Below in conjunction with accompanying drawing an embodiment of the present utility model is further described:
Visible multifunctional fracture seepage simulation test bench of the present utility model, the master is made of experiment table stage body 1-1, water system and experimental data proving installation.Experiment table stage body 1-1 is made by concrete; Water system is made of water pump 7 and circulating water line; The experimental data proving installation is made of flow sensor 4, pressure transducer 5 and by-pass valve control 3.Have many Inlet and outlet water crack passages 2 that are interconnected on the experiment table table top 1 of experiment table stage body 1-1, prefabricated crack piece 1-4 is housed in the crack passage 2, prefabricated crack piece 1-4 is made by gypsum; The crack water flowing interface 1-5 place of each crack passage 2 is provided with the water inlet pipe and water outlet pipe that constitutes the circulation path with water pump 7 respectively, be respectively equipped with flow sensor 4, pressure transducer 5 and by-pass valve control 3 on each water inlet pipe and water outlet pipe successively, each water inlet pipe porch is respectively equipped with sand inlet 1-8, gaza's funnel 6 is equipped with in the top of sand inlet 1-8, and gaza's funnel 6 is by last; Each crack passage 2 both sides is provided with rubber gasket 1-3, and is provided with the transparent cover plate 1-2 that is fixed on the rubber gasket 1-3, and transparent cover plate 1-2 is made by organic glass.Utilize rubber gasket 1-3 sealing, and transparent cover plate 1-2. is fixed on the experiment table table top 1 by screw 1-6 and nut 1-7.The height of making prefabricated crack piece 1-4 should make the gypsum part in non-crack fully to contact with transparent cover plate 1-2 a little more than rubber gasket 1-3, guarantees that water only flows in the crack of prefabricated crack piece 1-4.
Earlier the crack passage 2 of not putting prefabricated crack piece 1-4 is carried out water permeabillity test before the experiment, filling prefabricated crack piece 1-4 afterwards, owing to have certain water absorptivity after gypsum is fixed, it is unsuitable excessive when discharge begins in the experimentation, answer the low speed water flowing more than 10 minutes, make gypsum experimentize again after fully absorbing water, with the error that reduces to test.
