Accompanying drawing explanation
Fig. 1 is the structural representation of impermeability test instrument in embodiment;
Fig. 2 is sample fixing device enlarged diagram in embodiment.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As illustrated in fig. 1 and 2, a kind of New Geosynthetics impermeability test instrument, it comprises the constant temperature water tank 6, supercharge pump 5, water tank 1 and the sample fixing device 14 that connect successively; Add pure water by inlet valve 8 to constant temperature water tank 6, under driven by motor, pure water is pressed in water tank 1 by supercharge pump 5;
Water tank 1 is arranged a water tank water inlet 3 and a water tank water delivering orifice 16, water tank water inlet 3 is connected with supercharge pump 5 by pipeline, and a water tank water delivering orifice 16 is connected with controlled valve 13 by pipeline; A water tank pressure relief opening 17 of water tank 1 is connected with pressure relief valve 9 by water pipe, and water tank 1 is also provided with a water tank water discharging valve 2 and a water tank moisturizing valve 4.
Sample fixing device 14 comprises sample placement platform 23 and sample friction top 22, and sample placement platform 23 below in the middle of sample 20 is provided with high pressure sump 18, and the water inlet of high pressure sump 18 is connected with controlled valve 13 by pipeline; The opening of high pressure sump 18 covers by sample 20, is provided with O-ring seal 21 between sample 20 and high pressure sump 18; Sample friction top 22 is provided with groove 22a above sample 20, is provided with porous plate 19 in groove, is provided with water delivering orifice bottom groove 22a.Water outlet is provided with level measurement device 15.Level measurement device is the infiltration measurement mechanism with scale value.
Wherein, impermeability test instrument comprises 3-6 sample fixing device 14.
Impermeability test instrument also comprises the pressure controller with digital display 12 for controlling supercharge pump 5 pressure.
