Estudio Patológico del Puente “Estaqueca” Localizado Via Bogota – Villavicencio

Abstract

The “Estaquecá bridge” located at PR 46+150/46+189 of the Bogotá - Villavicencio road, is a structure that passes over the stream that bears the same name, built in 2005 in order to provide communication to the community of sector and passersby in the area, however, historically it has presented numerous problems of flooding and landslides in the area, which has caused pathologies to occur in the different elements that compose it, such as the pavement slab, the abutments, the beams post-tensioning and expansion joints, mainly reflected in cracks and detachments of the material that protects the reinforcing steel; Carrying out a vulnerability analysis, it was stated that there are risks that need mitigation and plans, laboratory tests corresponding to electrical conductivity (corrosion potential) were carried out, which showed that the probability is high that this process is not occurring, due to its On the other hand, the sclerometry and ultrasonic pulse tests determined that the concrete still had the resistance for which they were designed, so it was proposed to carry out a rehabilitation of the affected elements with a concrete coating and in the same way, a change of the asphalt plates was carried out. on the road, reconstruction of the metal railings and the installation of cables according to the structural recommendations.
