Avaliação de manifestações patológicas em bases de unidades armazenadoras de grãos da fronteira oeste

Abstract

This paper aims to describe the main events occurring in pathological bases for grain storage silos located in the border region west of Rio Grande do Sul were visited thirteen grain storage facilities in this region of the state. The port facilities had their own equipment and arrangements, but with common characteristics. Visits rose in all the pathological manifestations and visible from the number of occurrences, it was the most common. In order to understand the functioning and emergence of diseases carried out a literature review about grain storage facilities, storage silos in structures and pathologies. We describe the types of equipment most frequently used for storing grains, their characteristics and methods of construction of silos bases longer run by engineers and builders in the region. We analyzed characteristics of design, flowchart, operation and maintenance of the bases of silos. The survey and analysis of pathological manifestations were conducted with the aim of identifying the most frequent causes of these problems, which may be quite varied, ranging from construction problems, design, use or maintenance. The main conclusions of this research were: that there is a high occurrence of settlements, which appeared in 62% of facilities inspected, peeling caused by corrosion of reinforcement, and in union with the base metal structure, reached at 77% and 69%, the biological agents found in 54% and fissures and cracks that appear at 38% and other diseases with low incidence.
