Detailed Description

The following is further detailed by way of specific embodiments:

reference numerals in the drawings of the specification include: the device comprises a cylinder body 1, an installation seat 11, a positioning shaft 12, a closing plate 13, an air cylinder 14, a baffle plate 15, a water inlet channel 16, a rubber sleeve 2, a compression ring 3, a compression shaft 31, a protective layer 32, a cavity 41 and a fixed seat 42.

The embodiment is substantially as shown in figures 1 and 2: a double-sided sealing sleeve for a concrete impermeability test comprises a barrel body 1, wherein the barrel body 1 is hollow and is provided with an opening at the upper part. The upper portion and the lower part of barrel 1 are all fixed with rubber sleeve 2 with the screw, and the length of rubber sleeve 2 is 10 ~ 75 mm.

The coaxial taper fit in the outside of barrel 1 has clamp ring 3, and clamp ring 3 has a plurality of hold-down shaft 31 along its circumference equipartition, and the lower part of hold-down shaft 31 all bonds fixedly has protective layer 32, and protective layer 32 is made by elastic material, like rubber.

The lower part of barrel 1 integrated into one piece has mount pad 11, and it has inlet channel 16 to open on mount pad 11, and it has the spout to open on mount pad 11, and the horizontal smooth connection has baffle 15 in the spout, and baffle 15 is used for sealing inlet channel 16.
