EVALUACIÓN DEL COMPORTAMIENTO HIDRÁULICO Y MECÁNICO DE TUBOS DE HORMIGÓN ARMADO REVESTIDOS INTERNAMENTE CON POLIETILENO

Abstract

The residual fluids that are formed by domestic use, generate a number of bacterial agents that are carried with the same waters as they are: Sulfides, these must be treated with the utmost care since sediments caused by anaerobic organs result hydrogen sulfide, which is fixed on the inside of the pipe giving rise to the creation of hydrogen sulfide. The pipeline that works in a sanitary or pluvial drainage system must not only have sufficient resistance to the loads it supports, such as traffic and its filling material, its behavior must also be considered very cautiously against threats such as corrosion and the attack of the chemicals, factors that in the short term could deteriorate and end the useful life of the system which would turn into an expense and not a long-term investment. Our proposal and study is based on considering the benefits of the reinforced concrete pipe, among which its high mechanical resistance and ability to work on soils with high water tables; For this reason, we consider that it would be a great opportunity to use a HDPE coating because it is a high quality, environmentally friendly product that will protect the concrete from corrosive attacks, and will optimize its mechanical and hydraulic characteristics by 30%.
