Abstract

SE PROPONE UNA SONDA A BASE DE UN MEDIO DE PRESION PARA EL ENSANCHAMIENTO HIDRAULICO SIMULTANEO DE VARIOS TRAMOS LONGITUDINALES DE UN ARBOL HUECO. SEGUN EL INVENTO, LA SONDA CONSISTE EN DISTINTOS TRAMOS LONGITUDINALES. DE ESTE MODO, SE ABRE LA POSIBILIDAD DE REALIZAR SONDAS DE GRAN LONGITUD QUE NO PUEDEN OBTENERSE EN LA MODALIDAD DE CONSTRUCCION DE UNA SOLA PIEZA A CONSECUENCIA DE LA LONGITUD DE ANIMA NECESARIA. LA ESTRUCTURA DE LA SONDA PUEDE VARIARSE FACILMENTE; LAS JUNTAS DEFECTUOSAS PUEDEN CAMBIARSE SIN ESFUERZO.
