The bottom plate is equipped with centering seam allowance.
The bottom plate upper surface is equipped with upper heavy mouth, and internal diameter is slightly larger than test specimen big end outer diameter, heavy mouth outer circle and bottom plate outer circle
With one heart.Bottom plate lower end surface is equipped with sinking mouth.
Support ring is equipped in the tire, it uses elastic material, and exradius is equal to outside the die sleeve inner wall undercut groove
Radius of circle is reduced expenditure pushing out ring section thickness.
Using the beneficial effects of the invention are as follows hollow seal tire flexibility is good, contact pressure is easy to control, and can guarantee to mix
Solidifying soil test specimen sealing effect.When sealed tire pressure release, carcass is contracted in undercut groove under the action of support ring, between test specimen almost
Without opposite interaction, long service life is easy to operate, and does not pollute.Test specimen and die sleeve can be carried individually, die sleeve and bottom plate
It is fixed with tommyhead bolt, it is time saving and energy saving to operate.

Specific embodiment
Such as Fig. 1-Fig. 8, tire seals concrete impermeability test device, including die sleeve 1 and bottom plate 9.The die sleeve 1 be one with
Test specimen 5 has the hollow round table metal cylinder of identical taper.The internal diameter in any section of die sleeve 1 is slightly larger than the corresponding section of test specimen 5
Outer diameter.It puts die sleeve 1 and test specimen 5 are concentric and bottom surface is aligned, there is uniform unilateral gap between die sleeve 1 and test specimen 5.The mould
It covers 1 inner wall and is equipped with twice undercut groove, filling sealed tire 2 in undercut groove.1 big end outer rim of die sleeve is equipped with flange, and flange is circumferentially uniform
It is distributed several bolt slots.Bolt slot inner end is semi-cylindrical, and to external flange outer openings, bolt can be pushed into bolt slot from opening
Inner end.The bottom plate 9 is circular metal plate.9 upper end of bottom plate is equipped with closure gasket groove, and closure gasket groove and 9 outer circle of bottom plate are concentric.It is close
Filling sealed circle 8 in seal ring slot.Opened several tommyhead bolt slots on the bottom plate 9, the relatively narrow notch of tommyhead bolt slot upper, compared with
Wide notch penetrates through 9 upper and lower end face of bottom plate under.Tommyhead bolt slot is uniformly distributed circumferentially on bottom plate 9, and inner end is half
Cylindrical surface, to external 9 outer openings of bottom plate, bolt can be pushed into tommyhead bolt slot inner end on the outside of bottom plate 9.Tommyhead bolt slot inner end half
The center of circle on cylindrical surface and the center of circle distribution radius of circle having the same of 1 flange bolt slot semi-cylindrical of die sleeve.The bottom plate 9 is in
The heart is equipped with pipe screw thread through-hole 4, is circumferentially being evenly arranged bolt hole at outer circle.The 1 small end inner edge of die sleeve is equipped with limit
Shoulder 3, interior circular diameter are less than 5 end diameter of test specimen.After 5 lower end cut-in pressure water of test specimen, 5 lifting height of test specimen is by limiting
Shoulder 3 limits.The sealed tire 2 is equivalent to hollow O shape sealing ring, and pressure medium is pumped into or is discharged through interface 7.Right figure in Fig. 5
The state of shown sealed tire inner cavity no pressure medium, the state of charged pressure medium shown in left figure.The bottom plate 9 is equipped with centering
Seam allowance 13.9 upper surface of bottom plate is equipped with upper heavy mouth, and internal diameter is slightly larger than 5 big end outer diameter of test specimen, and heavy mouth outer circle and 9 outer circle of bottom plate are same
The heart.9 lower end surface of bottom plate is equipped with sinking mouth.Support ring 14 is equipped in the sealed tire.Support ring 14 uses elastic material, outer circle
Radius is equal to the die sleeve inner wall undercut groove exradius and reduces expenditure pushing out ring section thickness.Sealed tire inside support ring 14 acts on
In when sealed tire not yet charged pressure medium, carcass can be close to described sink under the action of 14 elasticity tension of support ring and cut
15 bottom surface of slot avoids carcass from protruding from 1 bore area of die sleeve.
Test specimen 5 is placed on bottom plate 9, test specimen 5 should be fallen in centering seam allowance 13.By 1 set of die sleeve on test specimen 5, under die sleeve
The alignment of end stand shoulder hole 16 centering seam allowance 13, such as Fig. 1, Fig. 6.In addition by the T shape spiral shell of bolt slot and bottom plate 9 on 1 flange of die sleeve
