Diagnóstico de las fisuras y filtraciones observadas en la placa del Puente Guamal ubicado en el K38+100 vía Villavicencio – Granada.

Abstract

The present study aims to diagnose the cracks and leaks observed in the slab of the Guamal Bridge, located at kilometer 38+100 on the Villavicencio–Granada Road, in order to identify their causes and propose corrective measures. For this purpose, a detailed technical evaluation was carried out, including visual inspections, structural surveys, and non-destructive tests, complemented by an analysis of environmental conditions, materials used, and construction methods employed in the bridge. Preliminary results indicate that the cracks are mainly associated with soil movements, repeated loads, temperature changes, differential settlements, and prolonged exposure to adverse climatic conditions typical of the region. On the other hand, the observed leaks result from the deterioration of expansion joints and an insufficient drainage system. Based on these findings, intervention strategies are proposed, including crack repair by performing high-pressure hydro-washing with water at 2000 PSI on all elements, surface preparation by scarifying and regularizing the section up to 8 cm behind the steel affected by corrosion, cleaning and protecting the reinforcement steel, applying a bonding agent, using low-shrinkage concrete for repair with a corrosion inhibitor, applying a corrosion inhibitor by impregnation, and injecting low-viscosity resin, such as methacrylate, into the cracks. This diagnosis contributes to the conservation of road infrastructure, ensuring its long-term functionality and safety.
