Method for removing section steel concrete column

The present application relates to the technical field of removing a section steel concrete column, and more particularly, the present application relates to a method for removing a section steel concrete column, comprising: determining a pre-blasting portion of the section steel concrete column according to a height dimension of the section steel concrete column; cutting a pre-blasting portion to obtain an initiation position, part of section steel being exposed at the section steel concrete column at the initiation position; a blasting object being provided at the part of section steel at concrete at the initiation position, the blasting object provided at the part of the section steel being a linear energy-concentrating cutter; detonating the blasting object to remove the section steel concrete column.

Flexible metal/metal oxide and/or intermetallic reactant ribbon cutting system

Provided is a blast-free alternative tool for breaching operations for the intended purpose of cutting metal, including rebar, steel cables, I-beams, thin walled containers, welding doors, and the like. The apparatus includes a flexible and cuttable tube containing metal oxide/metal (thermite) mixture, capable of being formed around a target material and of NONEL ignition. The apparatus can be used to cut, weld, or ignite target material. Protective caps are included with provisions to insert shock tube or time fuse to transmit ignition to first fire mix. A fire proof or flame retardant flexible outerwrap with adhesive (such as hydrogel) or malleable retention wires covers the cutting ribbon for heat and slag retention. In the preferred embodiment, the apparatus is issued/manufactured in rolls or precut lengths.

Select fire switch control system and method
10180050 · 2019-01-15 · ·

A select fire system and method for controlling operations in a gun string assembly includes perforating guns and switch subs mechanically connected in the gun string assembly. Each of the switch subs includes a switching element, input links and output links. The switch subs and perforating guns communicate with each other through the input and output links. The switching elements keep track of the state of the sub and switches states based on trigger conditions such as environment conditions, perforating gun conditions, or input conditions from surface.

Multi-configuration transportable demolition pouch

Provided is a multi-configuration transportable demolition pouch that includes a cruciform shaped section of fabric with a central explosive containing area and four trimmable flaps, a fastener on each of the flaps, a strap accepting slit, a first and a second strap, a fabric lid and priming hole, and one or more energetic device that can be selected based on desired blast footprint. The pouch can be trimmed when using smaller quantities of explosives to reduce its footprint and facilitate ease of carrying and emplacement. The device has attachment features to aid in transport and to provide proper spacing and attachment points for demolitions and breeching techniques involving multiple charges. The pouch provides components to allow for blast footprint alteration and for water tamping to reduce blast effects to nearby personnel, as well as to increase the efficiency of the explosive charge.
