Embodiment
With reference to accompanying drawing, a kind of permeability test device with air compressor machine, comprises test pipe 1, and the upper end of described test pipe 1 is connected with water tank 3 by the first pipe connecting 2, and the lower end of described test pipe 1 is connected by the 2nd pipe connecting case 5 that catchments with 4;
Described test pipe 1 is flexible pipe, described first pipe connecting 2 and the 2nd pipe connecting 4 are stereoplasm tube, all having offered annular groove 21 on the outer wall of described first pipe connecting 2 and the 2nd pipe connecting 4, the two ends of described test pipe 1 are all fastened in described annular groove 21 by flexible collar ring 6;
Described test pipe 1 is equipped with the grid 11 for placing soil sample along its cross section;
Described water tank 3 is provided with band cover gab, and described water tank 3 and the first air compressor machine 8 are tightly connected;
Being arranged with shell 7 outside described test pipe 1, described test pipe 1 is included in the air-tight inner chamber of described shell 7 by described shell 7, and described air-tight inner chamber is connected with the 2nd air compressor machine.
Described card garter spring 6 be can the resilient ring of folding, one end of described card garter spring 6 is provided with discount 61, and the other end is provided with buttonhole 62, and described card garter spring 6 realizes folding by the cooperation of discount 61 and buttonhole 62.
Described test pipe 1 is rubber hose.
Described first pipe connecting 2 and the 2nd pipe connecting 4 are all synthetic glass materials.
Described first pipe connecting 2 and the 2nd pipe connecting 4 are arranged with reinforcing ring 9, described first pipe connecting 2 and the 2nd pipe connecting 4 offer the groove 22 for loading described reinforcing ring 9.
Described shell 7 is provided with the weather gauge 71 for measuring its air-tight inner chamber.
Described grid 11 is woven wire, and described grid 11 is equipped with filter paper, and soil sample is placed on filter paper, prevents solid particulate from falling into and catchments in case.
