In structural joint, until overflowing structure is stitched, Seepage is found in filling process, after first breakthrough is blocked, be further continued for grouting.
Rubber bar diameter of the present invention is greater than structural joint seam width, and rubber bar diameter 3cm stitches width 1.8cm, and wall scroll structural joint is repaiied
Mend position pointing rubber bar and use one whole.
Former water sealing structure is filled up levelling by present invention flexibility sealing filler including pressing plate, makes bulge shape.
Stainless steel press strip of the present invention is covered in the both sides of sealing cover plate, and concrete is fixed on by stainless steel bolt
On face, the sealant under the bolt hole and periphery pointing suitable quantity of water of stainless steel bolt, make stainless steel bolt, concrete and
Sealing cover plate is integrally formed.
After the present invention fixes sealing cover plate, at sealing cover plate surrounding and stainless steel bolt, entered using underwater sealing agent
Row edge sealing, makes leakage preventing structure form the entirety without any leak path.
Beneficial effects of the present invention：
The present invention by the way of two ends grouting closing is combined, grouting envelope is carried out at seepage place two ends first using surface closure
Close, then carry out surface closure, form confined space, effectively prevent the formation of new leakage passage.

Specific embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples.
As shown in Figure 1, 2, a kind of new plugging technology under water, it is comprised the following steps：
（1）, dismounting structure seam surface water sealing structure, leakage scenarios are detected after dismounting, find out breakthrough；
（2）, the structural joint that determines around breakthrough, after the breakthrough in structural joint carries out leak stopping, structural joint is filled
Slurry；
（3）, on grout blanket embedded rubber bar, carried out from the lateral opposite side of structural joint one order during pointing, in pointing by rubber
Glue stick is tapped to seam, it is ensured that rubber bar is tightly embedded in seam；
（4）, after brushing bonding agent, pointing flexibility sealing material；
（5）, in sealing material external coating underwater bonding agent, pastes cover plate when applying, the brushing at sealing cover plate splicing seams gap
Underwater sealing agent, fixed sealing cover plate, edge sealing.
Further, the former water-stagnating effect of dismounting is poor, adsorb debris compared with multiple location, respectively extends 0.5m models during dismounting to both sides
Enclose, until exposing the preferable position of former sealing.
