Expansion water stop strip with glue injection hole

An expansion water-stop strip with glue injection holes comprises a water-stop strip body which is made of elastic sealing materials and used for plugging a leak or a joint, a plurality of glue injection holes are formed in the water-stop strip body at intervals, and the glue injection holes penetrate through the water-stop strip body and are used for injecting gel into the leak or the joint from the outside. The expansion water stop strip is provided with a plurality of glue injection holes, and gel can be directly injected into a leak or a joint through the glue injection holes in anti-seepage construction, so that the leak or the joint is blocked. Compared with the existing chemical grouting anti-seepage technology, the chemical grouting anti-seepage construction scheme adopting the expansion water stop strip has the advantages that an inclined hole does not need to be drilled in concrete, so that time and labor are saved, the strength of the concrete cannot be influenced, and meanwhile, concrete scraps ar
