Abstract
Un tubo de presión de concreto pretensado, caracterizado por un núcleo de tubo de concreto moldeado con una espiga teniendo una superficie anular para acoplar medios de sellamiento de junta, una envoltura de alambre tensado sometiendo el núcleo a compresión circunferencial, dicha envoltura-teniendo un extremo anclado cerca de dicha superficie de sellamiento de junta, dicho núcleo conteniendo una pluralidad de alambres pretensados espaciados circunferencialmente de dicho núcleo y extendiéndose substancialmente por la longitud del núcleo, un rizo pretensado contenido en el concreto de dicho núcleo, dicho rizo substancialmente concéntrico al eje de dicho núcleo y situado axialmente hacia adentro desde la cara de extremo del núcleo en el extremo de espiga del núcleo, dichos alambres pretensados acoplando el interior de dicho rizo y teniendo porciones desviadas radialmente hacia afuera desde sus puntos de acoplamiento con dicho rizo y hacia dicha cara de extremo en el extremo de espiga del núcleo.
