Abstract
The utility model relates to a three-hole columnar explosive tool with high performance, which is characterized in that a high explosion sensitive powder core is buried in a mixed powder column; the central hole of a powder column is the same as the central hole of the mixed powder column; both sides of the central hole are two detonating holes, one is a through hole; the other is a blind hole. The bottom of the mixed powder column is a groove, wherein, the mixed powder column is cast by the TNT and Tan mixture; the powder core is Tan explosive. The explosive can be detonated by a low-energy detonating cord, ordinary detonating cords and detonators. The utility model has high explosion speed, large power and low cost, and is widely suitable for large-scale civil engineering and hydraulic engineering.
Description
The utility model belongs to a kind of industrial pillar instrument that detonates.
The low sensitivity composite explosives of extensive use industry in large-scale civil engineering, hydraulic engineering.This low sensitivity explosive is pulpous state or ammonium nitrate-fuel oil mixture, is difficult to use the detonator direct initiation, must be by the relaying instrument detonation of detonating.Detonation tool generally is a pole structure, and the powder column composition contains more high-performance hexogen explosive, and cost is higher.
The purpose of this utility model is to provide the three hole column high-performance detonation tool that a kind of fried speed is high, power is big, cost is low.
This three hole column high-performance detonation tool that the utility model provides, form by mixing powder column, medicine core, shell, characteristics are that the medicine core is imbedded and mix in the powder column, medicine core centre bore is identical with mixing powder column centre bore, the centre bore both sides are two and lead blast hole, one is through hole, and another is blind hole, and mixing the powder column bottom is groove.Wherein, mix powder column and be TNT and mix medicine with pacifying very much, the medicine core is for pacifying very much medicine.
The utility model is the three hole column structure, and interstitial hole is used for the low energy fuse special hole, and two side openings are to wear detonator usefulness, also can be used for installing common fuse arming test experiment initiation explosive.And adopted the too peace medicine core of high detonation sensitivity, fried speed is high, power is big, the energy that detonates significantly increases, explosive fried Hong completely, the energy performance fully, improved fried Hong performance, direct cost reduces 20%, particularly uses in the heavy construction project and can save a large amount of expenses.
