Abstract

The invention provides a modularized two-way linear shaped charge cutter. The modularized two-way linear shaped charge cutter comprises at least one modularized cumulative cutter, charge positioning devices, detonation point positioning devices and cumulative direction determination devices. All the modularized cumulative cutters are of the same structure and are connected end to end in series. The corresponding detonation point positioning device is installed at the front end of the modularized cumulative cutter located on the head portion. The corresponding detonation positioning device is also installed at the rear end of the modularized cumulative cutter located on the tail portion. Meanwhile, the cumulative direction determination devices are also arranged at the rear end of the modularized cumulative cutter located on the tail portion. Each modularized cumulative cutter is sleeved with the corresponding charge positioning device, or the separated modularized cumulative cutters are sleeved with the charge positioning directions. According to the modularized two-way linear shaped charge cutter, modularized charge is adopted, the charge length can be determined according to requirements through any combination, the linear charge density is reasonable, charge positioning, detonation point positioning and cumulative cutting direction determining are accurate, and the modularized two-way linear shaped charge cutter can be applied to and popularized in most presplitting blasting and smooth surface blasting engineering.

Description

Technical field [0001] The invention belongs to the field of engineering blasting, in particular to a modular bidirectional linear energy-concentrating cutter. Background technique [0002] In recent years, with the rapid development of my country's national economic construction, in the construction of urban rail transit, tunnel excavation, civil air defense engineering excavation and cavern excavation, there are increasing requirements for the protection of surrounding rocks near the excavation site. The higher it is, the damage and disturbance to the surrounding rock needs to be reduced as much as possible, so pre-split blasting or smooth blasting is used. [0003] However, the traditional pre-splitting blasting or smooth blasting charging method still has limitations such as over-excavation, under-excavation, low half-porosity, large damage and disturbance to surrounding rock, and large vibration. [0004] It can be seen from the above that there is an urgent need for a blasting ...
