Abstract

La solicitud describe un canon de perforacion con un tubo exterior del canon en cuyo interior se halla dispuesto coaxialmente un tubo interior portador de perforadores que pueden ser hechos detonar mediante un cordon de voladura que pasa por el tubo del canon y que después de la detonacion perforan el tubo del canon de manera de formar orificios de disparo pasantes, habiéndose previsto un agente para el sellado u obturacion automáticos de los orificios de disparo pasantes después del disparo, y siendo dicho agente un medio capaz de hincharse. Para que el medio hinchable requiera solamente un espacio reducido en el canon de perforacion y sea fácil de integrar en el canon de perforacion, se propone de acuerdo con la presente que el medio hinchable esté dispuesto en forma plana en el interior del canon de perforacion.The application describes a drilling canon with an outer tube of the canon inside which an inner tube carrying cores is arranged coaxially that can be detonated by means of a blasting cord that passes through the canon tube and that after detonation pierces the canon tube so as to form through firing holes, an agent having been provided for automatic sealing or sealing of the passing firing holes after firing, and said agent being a means capable of swelling. In order for the inflatable medium to require only a reduced space in the drilling canon and to be easy to integrate into the drilling canon, it is hereby proposed that the inflatable means be arranged flat inside the drilling canon.
