Patologías del puente rio quera ubicado en la vía e59, que enlaza la provincia de El Oro y Azuay

Abstract

Pathologies of the “Río Quera” bridge located on road E 59, which connects the province of El Oro and Azuay. Oscar Ramiro Gia Belduma. 0704901719 The purpose of this degree work is to carry out an Analysis of the structural pathologies of the current state of the Río Quera bridge and present a proposal for corrective maintenance. For which a technical visit was carried out in situ, a visual inspection sheet of bridge pathologies was used, the same one that is proposed because there is no standardized format, said file will serve to identify the pathologies present in the bridge and establish the causes of them. The applied inspection sheet gave us the results that the most serious damage is found in the stirrups and equipment. In the abutments, it was possible to determine a fairly high percentage of humidity due to the installation of deteriorated water conduction pipes for the inhabitants' crops, for which they discovered the armor to hold the pipes which facilitates its corrosion. Another point that was analyzed in the left abutment is the segregation due to construction problems that a part of it has, where the armor is evident, creating an environment conducive to the oxidation of the armor. What was also found in the left abutment was that the reinforcement covering was not recommended by the AASHTO standards: Standard Specifications for Highway Bridges, which recommends that the minimum coverage measured from the concrete surface to the face of any bar reinforcement should not be less than 75 mm for concrete that is in contact with the ground.
