The utility model discloses further set up to: the sealant is polyurethane foaming glue.
Through adopting above-mentioned technical scheme, polyurethane foam rubber has good waterproof leaking stoppage performance, can block the steam that sees through in the first water proof space of upstream face one side, absorbs steam through expanded vermiculite, prevents that steam from entering into the basement.
The utility model discloses further set up to: and the pipe covers at the two ends of the waterproof casing pipe do not protrude out of the surface of the wall body at one side of the waterproof casing pipe.
The utility model discloses further set up to: and a waterproof coating for covering the pipe cover and the wall body around the pipe cover is brushed on one side of the wall body facing the water surface.
Through adopting above-mentioned technical scheme, waterproof coating can prevent that steam from permeating through from the gap between tube cap and the wall body, can play preliminary waterproof effect.
The utility model discloses further set up to: and a water stop ring is also arranged on the outer wall of the middle part of the waterproof sleeve.
Through adopting above-mentioned technical scheme, the stagnant water ring can block the steam of following the seeing through of protective sheath outer edge, has further improved this waterproof construction's waterproof performance.
The utility model discloses further set up to: the diameter of the expanded vermiculite is 2mm-4 mm.
Through adopting above-mentioned technical scheme, the space between the expanded vermiculite of this diameter within range is less each other, can promote the bloated compact ring of rubber after the inflation that absorbs water, makes its better carry out the shutoff to the gap between cable sleeve and the waterproof casing pipe, prevents permeating through of follow-up steam.
To sum up, the utility model discloses a beneficial technological effect does:
the sealant filled in the second waterproof cavity can block the water vapor which permeates through the sealant in the first waterproof cavity, so that the expanded vermiculite in the first waterproof cavity can fully absorb the water vapor expansion, the rubber expansion ring is extruded, the rubber expansion ring deforms, the gap between the cable sleeve and the waterproof sleeve is plugged again, and the stability and the waterproofness of the waterproof structure are improved.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
In the figure, 1, a waterproof sleeve; 11. a tube cover; 12. pouring holes; 2. a cable bushing; 3. a first water-proof cavity; 4. a second water-proof cavity; 5. a rubber expansion ring; 6. expanded vermiculite; 7. sealing glue; 8. a water-resistant coating; 9. a water stop ring; 10. a wall body.
Detailed Description
