Цель работы заключается в изучении работы и эффективности металлических гидрошпонок, предназначенных для гидроизоляции технологических швов. В статье представлены результаты экспериментального исследования металлических гидрошпонок из оцинкованного листа, установленных в емкостную конструкцию из монолитного железобетона, изготовленную в заводских условиях. Для обеспечения различных условий воздействия на гидрошпонку емкостная конструкция была изготовлена с двумя разноуровневыми технологическими швами по ее периметру. В результате заполнения емкости водой и наблюдения за гидрошпонками в специально изготовленных полостях было определено, что шпонки, установленные на эпоксидный клей, не обеспечивают герметичность, в отличие от шпонок, установленных при помощи силиконового герметика. Также экспериментально выявлены некоторые технологические достоинства и недостатки металлических гидрошпонок. Среди недостатков отмечена относительно высокая трудоемкость ее монтажа, в частности, стыковки элементов по длине. Среди основных технологических достоинств необходимо отметить собственную жесткость изделия. При этом необходимо дальнейшее изучение химического поведения металла гидрошпонки в теле бетона. В частности, необходимо выполнить эксперименты с повышенным давлением воды и исследовать поведение стали, изучить влияние геометрии гидрошпонки и химической активности «бетон конструкции – металл гидрошпонки» на величину предельного сопротивления гидростатическому давлению.</p></abstract><trans-abstract xml:lang="en"><p>The existing information on the study and application of tack weld metal waterstops in Russian construction practice is limited. The authors of the present paper investigate the operation and effectiveness of metal waterstops designed for waterproofing tack welds. An experimental study of metal waterstops made of zinc-coated sheets and installed in a factory-fabricated capacitive monolithic reinforced concrete structure was conducted. In order to provide different exposure conditions for a waterstop, a vessel structure was manufactured with two split-level tack welds on its perimeter. As a result of filling the vessel with water and monitoring the waterstops through special cavities, it was determined that the waterstops mounted with epoxy glue did not provide sufficient sealing, unlike those mounted with a silicone sealant. In addition, some technological advantages and disadvantages of metal waterstops were experimentally revealed. The disadvantages included a relatively high labor intensity of their installation, in particular, joining the elements along the length. The main technological advantage consisted in the inherent rigidity of the product. Further research should investigate the chemical behavior of the waterstop metal in the concrete body. To this end, the steel behavior under increased water pressure and the influence of the waterstop geometry and the chemical activity of the "structural concrete – waterstop metal" complex on the value of the hydrostatic pressure resistance limit should be elucidated.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гидроизоляция</kwd><kwd>технологический шов</kwd><kwd>металлическая гидрошпонка</kwd><kwd>поливинилхлоридная гидрошпонка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>waterproofing</kwd><kwd>technological seam</kwd><kwd>polyvinyl chloride waterstops</kwd><kwd>metal waterstops</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Liu S.M., Yu L., Gao J.X., Zhang X.D.
