The article presents the results of monitoring, technical inspection, and major repair of a transport-hydraulic structure – a dam with a culvert located within urban development. A set of measures aimed at ensuring slope stability, improving drainage efficiency, and reducing the risks of structural failure under hydrodynamic and traffic loads is described. In global practice, such tasks are solved through the integration of remote monitoring methods (UAV photogrammetry, InSAR, fiber-optic sensing) and trenchless rehabilitation technologies (CIPP, SAPL), which minimize roadway disruption and ensure long-term reliability of infrastructure.
A comprehensive assessment of the technical condition was carried out using visual, geodetic, ultrasonic, and impact-impulse methods. It was found that the culvert was in a limited operational condition due to soil erosion, masonry destruction, and deterioration of concrete channel lining. The main causes of defects were prolonged operation without repairs, dynamic loads from traffic, and the malfunction of surface water drainage.
The proposed repair measures included restoring the protective concrete layer of culverts with polymer-cement mortar, crack injection, construction of a new compacted embankment with reinforced slopes, concrete lining of the channel, and modernization of the drainage system. After completion, the structure’s functionality was restored, slope stability improved, and soil erosion risks reduced. The installation of new stormwater inlets and inspection wells, along with proper longitudinal and transverse road gradients, ensured effective surface runoff drainage and improved traffic safety.
The results obtained confirm the feasibility of using a combined systems approach to the inspection and repair of engineering structures.The integration of modern monitoring methods and restoration technologies ensures accurate defect diagnostics, reduces repair duration, and lowers maintenance costs. The implemented technical solutions have demonstrated their effectiveness in enhancing embankment stability, drainage reliability, and overall structural durability under conditions of dense urban development. The conducted study has practical significance for further improvement of monitoring and rehabilitation systems for engineering facilities during the post-war reconstruction period, taking into account the principles of sustainable development and civil safety.
