Abstract
The present invention relates to the field of explosives for use in demolition in public works. More specifically, it relates to an improved linear shaped charge that allows cutting a target material such as thick blocks (e.g. metal blocks) efficiently in the total length of the charge. In addition, the present invention also relates to a linear cutting charge system for cutting said target material and a method for cutting a target material by means of said linear shaped charge and system thereof.
Claims15
Linear cutting charge for cutting a target material, wherein the linear cutting charge comprises:
- a liner having a concave inverted V shape, wherein the liner comprises an inner surface and an outer surface, and wherein the outer surface conforms a hollow cavity,
- an explosive charge, having a longitudinal axis X-X′, located on top of the inner surface of the liner,
- a shock wave amplification element located on top of the explosive charge and comprising a hole configured for housing an external initiation means;
- and
- a shell having a cavity, wherein the shell is configured for housing the liner, the explosive charge and the shock wave amplification element;
- wherein
- the shock wave amplification element has the shape of a cylinder, having a width and a height, the height being greater than or equal to the width,
- the shock wave amplification element and the explosive charge are made of the same explosive material and are integrated in the linear cutting charge as one unique element which shows no separation or discontinuity between them.
The linear cutting charge according to claim Z, wherein the explosive material of the shock wave amplification element and the explosive material of the explosive charge is a cast-cured explosive selected from a plastic bonded explosive.
