Abstract

UNA DISPOSICION PARA DETECTAR LA PRESENCIA DE UNA CAVIDAD EN UNA PERFORACION PROYECTADA PARA RECIBIR A UN MEDIO DE REFORZAMIENTO QUE COMPRENDE UN TUBO DE MEDICION CON UN PASAJE, PORQUE EL TUBO DE MEDICION COMPRENDE AL MENOS UN MEDIO PARA SUMINISTRAR UN MEDIO DE MEDICION A LA PERFORACION DONDE EL MEDIO FUNCIONA COMO UNA VALVULA QUE SE ACTIVA CON LA APLICACION DE PRESION AL SUMINISTRAR ESTE MEDIO DE MEDICION AL PASAJE.A PROVISION TO DETECT THE PRESENCE OF A CAVITY IN A PROJECTED PERFORATION TO RECEIVE A MEANS OF REINFORCEMENT THAT INCLUDES A MEASUREMENT TUBE WITH A PASSAGE, BECAUSE THE MEASUREMENT TUBE UNDERTAKES AT LEAST ONE MEANS TO SUPPLY A MEASUREMENT MEASURE TO THE PERFORMANCE THE MEDIA WORKS LIKE A VALVE THAT IS ACTIVATED WITH THE PRESSURE APPLICATION WHEN SUPPLYING THIS MEASUREMENT MEASURE TO THE PASSAGE.
